The TSA medium provided a suitable environment for a variety of bacteria and a few molds. Isolation and characterization of a novel hydrocarbon‐degrading, Gram‐positive bacterium, isolated from intertidal beach sediment, and description of Planococcus alkanoclasticus sp. Many of the morphological and physiological analyses made on the isolate are not held by every species in the Planoccocus genus. Karlsruhe 1:235-238, p 1781 Genera related If any microbes grew from the firewood it would mean that they were able to withstand temperatures below -50 degrees Celsius and be psycrophiles, if any microbes grew in my wood stove they would have had to be thermophiles. penetrates wall of decolorized gram - cells gram negative appear red. Of the few documents that relate to Planococcus donhaensis, there is one that notes the origin of the sample, the South Korean Sea. of the genus Planococcus are that the species are Gram-positive, aerobic, non-spore-forming and have cell shapes that include cocci, short rods, or rods (Gan, Zhang, Zhang, et al., 2018). Abstract. compare with Marinococcus, Migula W. (1894) Uber Microscopically, it is a cocci-shaped bacterium measuring 0.5 to 0.7 μmin diameter (Fig. Arb. The gram-stain revealed that the isolate was a gram-positive coccid: Image 2. Cell lysis was accomplished through adding sodium dodecyl sulfate (SDS), which is a surfactant that chemically weakened the cell walls, and the use of PowerBeads and the centrifuge to mechanically break the cell walls. A series of patented solutions C1-4 were added following the protocol to purify and remove inhibitors and proteins until all that remained was a pure solution of DNA. The cell walls of Gram positive bacteria differ structurally from the cell … The catalase test produced bubbles and the oxidase test produced a blue color change on the strip indicating that the microbe was positive in both tests. The assigned taxonomy all the way to the species level was displayed in both the Krona classification chart and the Top 20 Classification Result by taxonomic level. The Isolate appeared to be a pure culture by the third quadratic streak; a fourth was performed for certainty. Isolated from sub-artic decomposing wood. Using Illumina’s BaseSpace dashboard to handle the data, the isolate’s genome was analyzed and compared to an existing database to search for similar sequences of DNA. The next app that was used was the Kraken Metagenomics, which provided taxonomic assignment. A suspension of the microbe in broth was tested simultaneously in all 21 of the tests included in the API 20E test strip. However these similarities are not enough to convince me that they are the same species. Micrococcus luteus 5. facultative anaerobes: Aerococcus viridans, Enterococcus, Overnight grown pathogenic bacterial strains of 1 × 10 6 CFU/mL were treated with known concentration of biosurfactants and incubated at … Micrococcus lylae 6. This app provided sample information such as the total number of reads that were used for classification and the percent of reads that were classified. The percent of contigs read needed to be greater than 80% and the percent of those reads that needed to agree upon a classification to trust that classification to the genus level was 80% and to the genus level was 60%. Micrococcaceae are not a coherent group. Phylogenetic composition and properties of bacteria coexisting with the fungus, de Boer W., van der Wal A. The sample was stained using the provided protocol, gram-positives and negative controls were compared to the isolate to determine its gram-state (lab 4). These tests reveal nothing more than a conformation that it is indeed a gram-positive microbe. Your email address will not be published. To control growth rates the plates were grown in incubators for 2-4 days at 37 degrees Celsius then moved to a refrigerator to ensure colonies did not grow large enough to touch. Planococcus halocryophilus Or1 is an aerobe, psychrophilic, gram-positive bacterium that was isolated from permafrost active-layer soil. Planomicrobium okeanokoites was reclassified from Flavobacterium okeanokoites. It is urease and catalase positive. The second most likely species suggested by was P. antarticus, at least this species shares a similar environment. nov. M. Engelhardt , K. Daly , R. Swannell , I. BLAST classified the organism as Planoccus donghaensis with a query cover of 77% and a 78% identity. Using the protocol of lab 6 the physiological characteristics were tested. Micrococcus kristinae 4. Taxonomic studies were performed on a novel carotenoid-producing strain, designated AJ003T, isolated from faeces of Antarctic penguins. Colonies are round and yellow in color. The final app Prokka Genome Annotation assigned gene regions that likely code for either tRNAs, rRNAs, CRISPRs and coding genes (CDs) and the abundance of them. Valášková V., de Boer W., Gunnewiek P. J. K., Pospíšek M., Baldrian P. (2009). In general, the colonies appear as white, smooth colonies. While under the microscope it was observed that the cells could be aligned linearly, in pairs or quads but not in a longer strep chain. The gram stain was performed to assess the thickness of the peptidoglycan wall. 1a). nov., a carotenoid-producing species isolated from stools of Antarctic penguins. radioresistant cocci called Deinococcus BaseSpace has many apps that provide different information about the genomic data. One representative of each from gram stain positive and gram stain negative bacteria was selected to further assess the MIC. These results reveal that the cells contained both cytochrome c-oxidase and the catalase enzyme respectively. To thrive in this community it would be helpful to have mechanisms to process radical oxygen species. This genus is relatively young and is currently growing with many of the species being described within the last ten years. The identification of this microbe would add to the depth of knowledge of what bacteria are and can be found on decomposing wood in the sub-artic. BLAST had a different database and could possibly have the genome of the isolates species if base space did not. An obligate aerobe, M. luteus is found in soil, dust, water and air, and as part of the normal microbiota of the mammalian skin. Planococcus sp. Tests were performed on the isolate by obtaining cells from either the TSA plates or from the slant agar. Table 2: Antibiotic Susceptibility Results. The susceptibility of the isolate to 8 different antibiotics was tested using the Kirby-Bauer Method agar and the disk diffusion test per the protocol of Lab 9. The genotypic test results for this microbe were vague, the results of BaseSpace had a low number of reads that could be classified and of those reads there was little consensus. Micrococcus, Pigments may be produced by some species; ranging from cream, pale yellow to light pink. See-Too, W. S., Ee, R., Lim, Y.-L., Convey, P., Pearce, D. A., Yin, W.-F., & Chan, K.-G. (2017). Several other species had similar query cover, including Planococcus antarticus: Image 7. By Ethan Hanson Classification: Kingdom: Bacteria Phylum: Firmicutes Class: Bacilli Order: Bacillaes Family:Planococcaceae Genus: Planococcus Species: Planococcus halocryophilus Planococcus halocryophilus is an aerobic, gram-positive bacterium that is found in arctic permafrost. (2008). Kraken Metagenomics app was only able to classify 2.67% of reads, and of those reads only 17% of those reads identified the microbe as Lysinibacillus sphaericus. These tests proved that the microbe could thrive in an oxygenated as well as an anoxic environment, that it contained cytochrome c oxidase which is a part of the electron transport chain found in microbes that utilize oxygen, and that it contained the catalase mechanism for dealing with oxidative damage, respectively. I was unable to grow any microbes from the wood stove but the growth from the previously frozen wood was abundant. PAMC21323 are shown in Table 1. The APP provides an extensive list of regions that were specifically identified as the above elements. While the cells were prepped in slides some characteristics were observed with the microscope, such as cell alignment shape and length. Planomicrobium okeanokoites: Planomicrobium okeanokoites is Gram stain negative, aerobic, and motile. Stomatococcus Firmicutes / “Bacilli” / Bacillales / Planococcaceae / Planococcus Cells coccoid , 1.0–1.2 µm in diameter, occurring singly, in pairs, in groups of three, or as tetrads or clumps of cells. This is consistent with a study that found, to the level of the genus, that Planococcus’ were susceptible to all antibiotics tested3. Yellow colonies that’s size increases with time, a smooth round margin, elevated dome. The first publication of a species under the genus Planococcus was P. citreus. coccus-shaped colony-forming The gram stain was performed to assess the thickness of the peptidoglycan wall. Micrococcus luteus is a Gram-positive, to Gram-variable, nonmotile, coccus, tetrad-arranging, pigmented, saprotrophic bacterium that belongs to the family Micrococcaceae. The gram-stain was repeated three times before a successful stain was accomplished. Genus planococcus. Throughout the course of this study I isolated one colony and performed many physiological and genomic tests to identify what species my isolate was. Member of the genus Staphylococcus are associated with clinical infections whereas that of Micrococcus are rarely involved in infection. My isolate was not just aerobic but a facultative aerobe, which is inconsistent with two articles that state the genus is strictly aerobic5. Gram‐positive to Gram‐variable. Antibiotic resistance of bacterial isolates from sediments of eastern Mediterranean Sea in association with environmental parameters. BLAST suggested Genus and species with associated query cover percentage and identity percentage. Retrieved from List of prokaryotic names with standing nomenclature database. The cells were measured to be 1 micrometer in diameter. (2016). Sarcina, Catalase positive:Deinococcus,Marinococcus Gram stain. but poor growth less than 1% or more than 15% NaCl A Gram-staining-positive and aerobic coccus with the ability to degrade petroleum bacterium, designated Y42T, was isolated from the Lenghu oil field located in the northern margin of the Qaidam Basin. Image 6 To 20 Classification Results by Taxonomic Level from BaseSpace. The Microbes transfer to the agar slant was successful: Image 1, and was successfully re-cultured from the slant when necessary. The Prokka Genome Annotation app identified 64 tRNAs, 0 rRNAs, 1 CRISPR, and 3739 CDS. Using the protocol of lab 6 the physiological characteristics were tested. mucilaginsosus. The firewood pile was slowly decomposing, and it is likely that the microbe that was isolated from it was a part of the community that was utilizing the wood as an energy source. The isolate failed to grow on EMB or MAC plates, considering that both plates are selective for gram negative, these results confirm the results of the gram positive test: Image 4. Micrococcus is closely related to Arthrobacter , Planococcus is related to Bacillus, Additionally the isolate underwent the thioglycolate test- for oxygen class, oxidase test- for the presence of cytochrome c-oxidase, and lastly the catalase test- for the presence of catalase enzyme. nov. isolated from cyanobacterial mat samples collected from ponds in Antarctica. The bacterium was found to be aerobic and Gram-stain positive. The isolate was found to be susceptible to all antibiotics tested with the disk diffusion test. Fackrell, H. (n.d.). P. donghaensis may have had the ability to deal with these temperatures in its genome, but it is not certain since it’s environment doesn’t select for such characteristics. After a two-day waiting period while the microbe was given the opportunity to develop where it could, the diameter of prohibited growth was measured and compared to standard antibiotic specific diameters and then classified as either susceptible, intermediate or resistant. While under the microscope it was observed that the cells could be aligned linearly, in pairs or quads but not in a longer strep chain. The SPAdes Genome Assembler provided the overall result of the genomes assembly. Bacteria Bacillus megaterium, Enterobacter gergoviae and Planococcus citreus can describe histidin as histamin. Micrococcus roseus 8. The results did not meet these thresholds, and this is the reason that the BaseSpace indentified taxanomy of Lysinibacillus sphaericus was rejected. , while the They are prokaryotic in nature meaning they are the earliest forms of the cell without a nucleus.. The antibiotics tested were Amikacin, Cefazolin, Cefoperazone, Gentamicin, Piperacillin, Tobramycin, Trimethoprim and Vancomycin. The general features of Planococcus sp. to the Genus. To conclusively Identify the taxonomy of this isolated microbe, it would be advisable to repeat DNA isolation and genomic analysis that was preformed in this project, and to additionally perform other genotypic analyses like, DNA-DNA hybridization and 16s rRNA analysis and fatty acid identity. The microbe was susceptible to all eight antibiotics tested. Of this information, only the number of contigs that were greater than 1000 base pairs long [# contigs (>=1000bp)], The total length of the assembled genome, the longest contig and the guanine and cytosine percentage in the genome (GC%) were observed. The sample was streaked using the quadratic method to grow pure isolated colonies onto a tryptic soy agar (TSA) plate. Considering the limit of species identified to this date, there is the potential that this microbe could be a new species. Dna was extracted and purified from the isolates cells using protocol from lab 5. Image 5 and 6 are from the Kraken app. Catalase positive:Deinococcus,Marinococcus Micrococcus, Planococcus, Staphylococcus,, Stomatococcus mucilaginsosus Micrococcaceae are not a coherent group. The multiple sequence alignments of 16S rRNA and housekeeping genes showed that … The oxygen class determined by the fluid thioglycolate test and the positive results of the Oxidase and Catalase test are both consistent with the oxygenic environment that the microbe was isolated from. The literature on the Planococcus species like donghaensis, kocurii, halocryophilus and antarticus often notes how closely related the species are and how further analysis like G-C content, fatty acid strains, DNA-DNA hybridization etc1,2 are needed to differentiate the species. The morphological characteristics that are consistent with the isolate and across the genus are: gram-positive membranes, cocci cell shape, colonies are yellow orange in color, catalase positive and an aerobic oxygen class5. Gram Positive Bacteria. The gram-stain was repeated three times before a successful stain was accomplished. Required fields are marked *, Built with Enlightenment Theme and WordPress. Planococcus faecalis sp. Obligate Aerobic Colonies after 24 hours, gray white, convex and 0.5-1 mm, after 48-72 hours, mucoid to very mucoid, no pigment, non hemolytic “Interactions between saprotrophic basidiomycetes and bacteria,’ in. Craters may form around the colonies on some media. The DNA was then sent to the UAF’s DNA Core Lab sequenced using the Illumina MiSeq DNA sequencer which utilized the next-generation sequencing methodology. Each of those colonies represented a microbe that had the physiological capability of surviving those conditions, and I was interested in observing them in the lab. Planococcus, Staphylococcus,, The negative results and lack of growth in the API 20e, MAC, and EMB are all consistent with the microbe’s gram-positive cell wall. Further analysis of the genomic information was necessary. Jeong-Hwa C, Wan-Taek I, Qing-Mei L, Jae-Soo Y, Jae-Ho S, Sung-Keun R, Dong-Hyun R. Reddy G, Prakash J, Vairamani M, Prabhakar S, Matsumoto G. Shivaji S. Tuncer, I. A novel Gram-stain-positive, coccoid or short rod-shaped, moderate-orange-pigmented, halotolerant and psychrotolerant bacterium, designated strain SCU63 T, was isolated from a saline soil sample in China, and characterized by a polyphasic taxonomic approach. These communities emit extracellular enzymes to decay the wood, this results in an environment with high acidity and enzymes that are producing free radical oxygen species7. It forms orange colonies and grows at NaCl concentrations of 2-10 % (w/v) (optimum, 4 % w/v), at 4-50 °C (optimum, 30 °C) and at pH 6.0-10.0 (optimum, pH 7.0). Planococcus antarcticus and Planococcus psychrophilus spp. At the genus level, morphology can vary greatly. Micrococcus nishinomiyaensis 7. PAMC21323 is a gram (+), motile, psy-chrotrophic bacteria, which can grow over a broad temperature range (5–40 °C). Considering that the API 20e test is designed for enteric gram negative microbes these results are confirmation that the microbe is gram-positive. Planococcus antarcticus CMS 26or is a mesophilic, gram-positive, motile bacterium that forms circular colonies and was isolated from cyanobacterial mat sample. the following information is not yet verified. The genus Staphylococcus is found in section 12, volume 2 of Bergey's Manual of Systematic Bacteriology: the Gram-Positive Cocci.The section includes aerobic genera (Micrococcus, Planococcus and Deinococcus), facultatively anaerobic genera (Staphylococcus, Stomatococcus, Streptococcus, Leuconostoc, Pediococcus, Aerococcus and Gemella) and anaerobic genera (Peptococcus, … The species classification with the highest query cover is poorly documented in literature. Planococcus. The thioglycolate test had growth throughout the agar with thicker growth at the surface, which revealed that the microbe’s oxygen class was facultative aerobe. The sample was collected from a dry piece of wood. An orange pigmented bacterium, S1, was isolated from a cyanobacterial mat sample collected in the vicinity of Schirmacher Oasis, Maitri, the Indian station, inAntarctica. masc. Bacterium Planococcus halocryophilus that is able to thrive at minus 15 degrees Celsius offers clues about microbial life on both Mars and Enceladus. Colony morphology on the TSA agar revealed a yellow colony that’s size increased with time, a smooth round margin and the colony was an elevated domed. Once identified, I could then research the species and compare it’s physiology and genomic data to current literature to confirm the taxonomic assignment. Planococcus citri, commonly known as the citrus mealybug, is a species of mealybugs native to Asia.It has been introduced to the rest of the world, including Europe, the Americas, and Oceania, as an agricultural pest.It is associated with citrus, but it attacks a … Planococcus citreus is Gram stain positive and aerobic. P. antarticus thrived in an Antarctica, my sample would likely have similar mechanisms for surviving temperatures around -45 degrees Celsius in Faribanks winters. Inst. I sampled two places, a piece of wood from my fire wood stack (which is exposed to the extreme cold temperatures of Alaskan winters) and the ashes from my stove. The analysis of the DNA with BaseSpace revealed unreliable data. There are some qualities that are consistent between my sample and P. donghaensis, they are both, gram-positive, aerobic, coccus and oxidase positive 1. coccus-shaped gram-positive The genus Planococcus was originally proposed by Migula [1] to accommodate Gram-stain-positive, aerobic and motile cocci of the family Planococcaceae in the phylum Firmicutes. Gemella The quadratic streak was used 4 times to ensure a pure culture. Micrococcus halobius 3. haemolysans, Lactococcus Leuconostoc, Based on multiple The results of the SPAdes Genome Assembler were above required values; # contigs >=1000 bp should be in the hundreds, total length should be at least a million bp and the longest contig should be at least 100000 bp.
