General characteristics and taxonomy Natural habitat. 16S rRNA gene sequencing analysis of the bacterial isolates identified species from several genera, including Halomonas, Bacillus, Kushneria, Virgibacillus, Planococcus, Pseudomonas, and others. The main characteristic of Planococcus citreus surfactant was the formation of oil-in-water emulsions, while water-in-oil emulsions characterized Pantoea agglomerans surfactant. The traditional phenotypic tests are commonly used in actinobacterial identification. Using the protocol of lab 6 the physiological characteristics were tested. An analysis of this strain's phenotypic, chemotaxonomic, and genomic characteristics established the relationship of the isolate with the genus Planococcus.Strain Y74 T was able to grow between 4 and 42°C (with an optimum temperature of 28°C) at pH values of 6â8.5 and in 0%â7% (w/v) NaCl. The classical phenotypic characteristics of actinobacteria comprise morphological, physiological, and biochemical features. nov. strain ES2T, together with the description of the complete genomic sequence and its annotation. Thirteen orange-pigmented bacteria associated with cyanobacterial mat samples collected from four different lakes in McMurdo, Antarctica, were isolated. Here we present a summary classiï¬cation and a set of fea-tures for the type strain Planococcus massiliensis sp. A NEW SPECIES OF PLANOCOCCUS, P. KOCURH ISOLATED FROM FISH, FROZEN FOODS, AND FISH CURING BRINE ... according to their biochemical and chemotaxonomic characteristics. masc. Planococcus is a Gram-positive, psychrotolerant, halophilic bacterium, which was initially proposed by Migula (1994) in 1894. nov. and Marinococcus halophilus (Novitsky and Kushner) comb. This assignment is consistent with the morphology and physiological characteristics of the organism. Morgen Southwood April 26, 2017 . Micrococcus are found in soils and fresh water, and frequently on the skin of humans and other animals. genomic characteristic of both endosymbionts is their low gene density (already noticed in  for T. princeps) and the large average length of the intergenic regions, in which no traces of homology with coding regions of other bacteria can be found. Bacterial growth at â15 °C; molecular insights from the permafrost bacterium Planococcus halocryophilus Or1. be applied to all the bacterial genus [6â8]. The structural characteristics of the strain Y42T genome provided a competitive advantage for better survival in petroleum-polluted environments. Two bacterial species with the ability to produce biosurfactants were isolated from a pesticide contaminated soil and identified as Planococcus rifietoensis IITR53 and Planococcus halotolerans IITR55. Isolated from sub-artic decomposing wood. characteristics, such as the presence of menaquinone 7 and menaquinone 8 as major isoprenoid quinones, ... Planococcus and that the description of the genus Pfunococcus should be emended. - Bergey et al. paper highlights characteristics of a group of 5 Gram-positive nonmotile coccoid bacteria identified as belonging to the genera Micrococcus and Planococcus. They occur in pairs, tetrads or clusters but not in chains. Micrococcus are aerobic, Gram-positive cocci ranging in size from 0.5 to 2.0 Î¼m in diameter. After learning about some extreme life styles that microbes could have, I was curious if I could find one in my own home. Extracted pigments from cold-adapted bacteria showed multiple absorption peaks between 400-550 nm, characteristic of carotenoid pigments11,12. Five strains were regarded as belonging to a new species in the genus Planococcus, and Planococcus kocurii Hao and Komagata sp. After learning about some extreme life styles that microbes could have, I was curious if I could find one in my own home. Therefore, we regard these strains as belonging to a new genus, and propose the genus Marino-coccus for such bacteria. Although these traits are unusual in bacterial endosymbionts, they have also been An obligate aerobe, M. luteus is found in soil, dust, water and air, and as part of the normal microbiota of the mammalian skin. It has been reported on over 200 host-plant species belonging to 191 genera and 82 families, and can seriously damage many crops, particularly citrus and glasshouse tomatoes. Planococcus Species â Untapped Marine Resource for the Production of Biosurfactant and Other Metabolites. nov. Quorum quenching (QQ) is the disruption of bacterial cell-to- cell communication (known as quorum sensing), which has previously been described in mesophilic bacteria. The Planococcus sp. Introduction . Despite having such old history, Planococcus was not reported in the public domain validly for several years.Kocur et al. Planococcus is a Gram-positive halotolerant bacterial genus in the phylum Firmicutes, commonly found in various habitats in Antarctica. PAMC21323 is a yellow pigment-producing bacterium isolated from King George Island in Antarctica; it has a broad growth temperature range of 5â40 °C. nov. is â¦ Introduction . Combined with the 16S rRNA gene and genome sequence, phenotypic as well as chemotaxonomic characterisations, strain Y42T is considered to represent a novel species of the genus Planococcus, for which the name Planococcus lenghuensis sp. Planococcus sp. by Joelle Renstrom, Astrobiology Magazine, Astrobiology Magazine Bacteria were isolated from the rhizosphere and as root endophytes associated with Salicornia rubra, Sarcocornia utahensis, and Allenrolfea occidentalis, three native Utah halophytes. Thirteen orange-pigmented bacteria associated with cyanobacterial mat samples collected from four different lakes in McMurdo, Antarctica, were isolated. Bacterial survival in salty antifreeze raises hope for life on Mars and icy moons. Formation of froth indicating the surfactant production was observed when grown in basal salt medium containing 2% glucose. Planococcus citreus Migula ATCC ® 14404 â¢ freeze-dried For-Profit: $550.00 Non-Profit: $467.50 Twelve of the isolates, which were coccoid in shape, were very similar and possessed all the characteristics of the genus Planococcus and represented a new species, which was assigned the name Planococcus antarcticus sp. The culture supernatant after 72 h showed reduction in â¦ Planococcus sp. Strain Y74 T was an isolate from the sandy soil in the town of Huatugou, QinghaiâTibet Plateau, China. Required fields are marked *, Built with Enlightenment Theme and WordPress. Because of the above properties, Planococcus exhibited a potential capability in the bioremediation of extremely contaminated environments. Twelve of the isolates, which were coccoid in shape, were very similar and possessed all the characteristics of the genus Planococcus and represented â¦ Morgen Southwood April 26, 2017 . Many species of Planococcus have been isolated from diverse environments such as high Arctic permafrost, marine solar saltern, pigeon faeces, sea water, soil and cyanobacterial mats13,14. Materials and methods Soil samples were collected at random sites around lake Zub, Schirmacher oasis (70°45'12"S and 11°46'E), Antarctica, in the third week of January 1985. Meanwhile, most of the Planococcus bacteria have showed the ability to withstand heavy metals, produce surfactants and adapt to cold and/or saline environments [12â14]. These characteristics differ significantly from those of the type species (Planococcus citreus) of the genus Planococcus. A phylogenetic analysis of the 16S rRNA gene sequence of this organism showed that it is a member of the genus Planococcus. Physiology, characteristics and genomic data for the microbial strain S23F2 (=ATCC 700539 =CIP 105673 =DSM 13963). They constitute the basis for the formal description of taxa, from species and subspecies up to genus and family. 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 â¦ bacterial strains produced distinct biosurfactants. At present the genus comprises eight recog- nized species, Planococcus citreus (Migula, 1894), Plano- Strain K22-03T and the three closely related organisms given coccus kocurii (Hao & Komagata, 1985), Planococcus above were grown on TSA and tested for morphological, alkanoclasticus (Engelhardt et al., 2001), Planococcus physiological and chemotaxonomic characteristics. Characteristics. Although many studies have reported the genomic backgrounds of Planococcus â¦ This laboratory-based study demonstrates that different compositions of microbial communities with similar functional characteristics can enable complete algal morphogenesis and thus supports the âcompetitive lotteryâ theory for how symbiotic bacteria drive algal development. (2) created the genus Flavobacterium for aer- obic, yellow-pigmented rods which produce acid from carbo- hydrates weakly. Planococcus is a Gram-positive halotolerant bacterial genus in the phylum Firmicutes, commonly found in various habitats in Antarctica. Herein, we describe the complete genome sequence information of the genus Planococcus with its annotated sequence, genetic features for bioremediation, and oxidative stress capacity. A gene encoding a beta-galactosidase in this isolate was cloned in an Escherichia coli host. Twelve of the isolates, which were coccoid in shape, were very similar and possessed all the characteristics of the genus Planococcus and represent â¦ Planococcus antarcticus and Planococcus psychrophilus spp. 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. nov.
