Thirteen orange-pigmented bacteria associated with cyanobacterial mat samples collected from four different lakes in McMurdo, Antarctica, were isolated. Isolated from sub-artic decomposing wood. Because of the above properties, Planococcus exhibited a potential capability in the bioremediation of extremely contaminated environments. The soil bacterial strains produced distinct biosurfactants. Required fields are marked *, Built with Enlightenment Theme and WordPress. by Joelle Renstrom, Astrobiology Magazine, Astrobiology Magazine Here we present a summary classification and a set of fea-tures for the type strain Planococcus massiliensis sp. Planococcus Species – Untapped Marine Resource for the Production of Biosurfactant and Other Metabolites. General characteristics and taxonomy Natural habitat. Herein, we describe the complete genome sequence information of the genus Planococcus with its annotated sequence, genetic features for bioremediation, and oxidative stress capacity. An obligate aerobe, M. luteus is found in soil, dust, water and air, and as part of the normal microbiota of the mammalian skin. Extracted pigments from cold-adapted bacteria showed multiple absorption peaks between 400-550 nm, characteristic of carotenoid pigments11,12. Planococcus sp. 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. A NEW SPECIES OF PLANOCOCCUS, P. KOCURH ISOLATED FROM FISH, FROZEN FOODS, AND FISH CURING BRINE ... according to their biochemical and chemotaxonomic characteristics. Bacterial growth at −15 °C; molecular insights from the permafrost bacterium Planococcus halocryophilus Or1. be applied to all the bacterial genus [6–8]. Planococcus citri is a highly polyphagous, adaptable mealybug that can feed on many host plants in a variety of conditions, and can reproduce rapidly. The culture supernatant after 72 h showed reduction in … A gene encoding a beta-galactosidase in this isolate was cloned in an Escherichia coli host. Morgen Southwood April 26, 2017 . Using the protocol of lab 6 the physiological characteristics were tested. Planococcus is a Gram-positive, psychrotolerant, halophilic bacterium, which was initially proposed by Migula (1994) in 1894. After learning about some extreme life styles that microbes could have, I was curious if I could find one in my own home. nov. is … Twelve of the isolates, which were coccoid in shape, were very similar and possessed all the characteristics of the genus Planococcus and represent … Planococcus antarcticus and Planococcus psychrophilus spp. Although these traits are unusual in bacterial endosymbionts, they have also been Micrococcus are found in soils and fresh water, and frequently on the skin of humans and other animals. 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 6–8.5 and in 0%–7% (w/v) NaCl. 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. Therefore, we regard these strains as belonging to a new genus, and propose the genus Marino-coccus for such bacteria. The classical phenotypic characteristics of actinobacteria comprise morphological, physiological, and biochemical features. Planococcus is a Gram-positive halotolerant bacterial genus in the phylum Firmicutes, commonly found in various habitats in Antarctica. The biosurfactant production of Planococcus citreus was 2.014 g/L, more than twice the Pantoea agglomerans production, which was 0.87 g/L. nov. strain ES2T, together with the description of the complete genomic sequence and its annotation. 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. They occur in pairs, tetrads or clusters but not in chains. PAMC21323 is a yellow pigment-producing bacterium isolated from King George Island in Antarctica; it has a broad growth temperature range of 5–40 °C. Thirteen orange-pigmented bacteria associated with cyanobacterial mat samples collected from four different lakes in McMurdo, Antarctica, were isolated. This laboratory-based study demonstrates that different compositions of microbial communities with similar functional characteristics can enable complete algal morphogenesis and thus supports the ‘competitive lottery’ theory for how symbiotic bacteria drive algal development. This assignment is consistent with the morphology and physiological characteristics of the organism. (2) created the genus Flavobacterium for aer- obic, yellow-pigmented rods which produce acid from carbo- hydrates weakly. Morgen Southwood April 26, 2017 . The Planococcus sp. 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. 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. They constitute the basis for the formal description of taxa, from species and subspecies up to genus and family. 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. These characteristics differ significantly from those of the type species (Planococcus citreus) of the genus Planococcus. Each isolate … 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 … Five strains were regarded as belonging to a new species in the genus Planococcus, and Planococcus kocurii Hao and Komagata sp. Physiology, characteristics and genomic data for the microbial strain S23F2 (=ATCC 700539 =CIP 105673 =DSM 13963). The main characteristic of Planococcus citreus surfactant was the formation of oil-in-water emulsions, while water-in-oil emulsions characterized Pantoea agglomerans surfactant. 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. - Bergey et al. Bacterial survival in salty antifreeze raises hope for life on Mars and icy moons. Characteristics. genomic characteristic of both endosymbionts is their low gene density (already noticed in [16] 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. A phylogenetic analysis of the 16S rRNA gene sequence of this organism showed that it is a member of the genus Planococcus. The traditional phenotypic tests are commonly used in actinobacterial identification. Isolated from sub-artic decomposing wood. 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. Despite having such old history, Planococcus was not reported in the public domain validly for several years.Kocur et al.

Although many studies have reported the genomic backgrounds of Planococcus … Bacteria were isolated from the rhizosphere and as root endophytes associated with Salicornia rubra, Sarcocornia utahensis, and Allenrolfea occidentalis, three native Utah halophytes. Two species are recognized in this genus, Marinococcus albus sp. 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. Quorum quenching (QQ) is the disruption of bacterial cell-to- cell communication (known as quorum sensing), which has previously been described in mesophilic bacteria. Bacterial growth at −15 °C; molecular insights from the permafrost bacterium Planococcus halocryophilus Or1 N. Mykytczuk , S. Foote , Chris R. Omelon , G. Southam , … nov. and Marinococcus halophilus (Novitsky and Kushner) comb. Introduction . Formation of froth indicating the surfactant production was observed when grown in basal salt medium containing 2% glucose. Strain Y74 T was an isolate from the sandy soil in the town of Huatugou, Qinghai–Tibet Plateau, China. 16S rRNA gene sequencing analysis of the bacterial isolates identified species from several genera, including Halomonas, Bacillus, Kushneria, Virgibacillus, Planococcus, Pseudomonas, and others. paper highlights characteristics of a group of 5 Gram-positive nonmotile coccoid bacteria identified as belonging to the genera Micrococcus and Planococcus. Meanwhile, most of the Planococcus bacteria have showed the ability to withstand heavy metals, produce surfactants and adapt to cold and/or saline environments [12–14]. Four strains were those of Planococcus citreus Migula 1894. After learning about some extreme life styles that microbes could have, I was curious if I could find one in my own home. Introduction .
