Four strains were those of Planococcus citreus Migula 1894. Planococcus citreus Migula ATCC ® 14404 ™ freeze-dried For-Profit: $550.00 Non-Profit: $467.50 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]. The biosurfactant production of Planococcus citreus was 2.014 g/L, more than twice the Pantoea agglomerans production, which was 0.87 g/L. They constitute the basis for the formal description of taxa, from species and subspecies up to genus and family. 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. Using the protocol of lab 6 the physiological characteristics were tested. (2) created the genus Flavobacterium for aer- obic, yellow-pigmented rods which produce acid from carbo- hydrates weakly. Although these traits are unusual in bacterial endosymbionts, they have also been 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. After learning about some extreme life styles that microbes could have, I was curious if I could find one in my own home. This assignment is consistent with the morphology and physiological characteristics of the organism. bacterial strains produced distinct biosurfactants. 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. 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 … The classical phenotypic characteristics of actinobacteria comprise morphological, physiological, and biochemical features. General characteristics and taxonomy Natural habitat. The traditional phenotypic tests are commonly used in actinobacterial identification. A phylogenetic analysis of the 16S rRNA gene sequence of this organism showed that it is a member of the genus Planococcus. 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. 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. Bacterial survival in salty antifreeze raises hope for life on Mars and icy moons. Micrococcus are found in soils and fresh water, and frequently on the skin of humans and other animals. nov. Planococcus sp. Characteristics. nov. strain ES2T, together with the description of the complete genomic sequence and its annotation. masc. Morgen Southwood April 26, 2017 . Strain Y74 T was an isolate from the sandy soil in the town of Huatugou, Qinghai–Tibet Plateau, China. They occur in pairs, tetrads or clusters but not in chains. 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. Planococcus is a Gram-positive, psychrotolerant, halophilic bacterium, which was initially proposed by Migula (1994) in 1894. An obligate aerobe, M. luteus is found in soil, dust, water and air, and as part of the normal microbiota of the mammalian skin. 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. - Bergey et al. Morgen Southwood April 26, 2017 . 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. paper highlights characteristics of a group of 5 Gram-positive nonmotile coccoid bacteria identified as belonging to the genera Micrococcus and Planococcus. The soil Introduction . Herein, we describe the complete genome sequence information of the genus Planococcus with its annotated sequence, genetic features for bioremediation, and oxidative stress capacity. Extracted pigments from cold-adapted bacteria showed multiple absorption peaks between 400-550 nm, characteristic of carotenoid pigments11,12. The structural characteristics of the strain Y42T genome provided a competitive advantage for better survival in petroleum-polluted environments. Here we present a summary classification 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. Planococcus is a Gram-positive halotolerant bacterial genus in the phylum Firmicutes, commonly found in various habitats in Antarctica. 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. Bacterial growth at −15 °C; molecular insights from the permafrost bacterium Planococcus halocryophilus Or1. nov. is … Planococcus is a Gram-positive halotolerant bacterial genus in the phylum Firmicutes, commonly found in various habitats in Antarctica. The main characteristic of Planococcus citreus surfactant was the formation of oil-in-water emulsions, while water-in-oil emulsions characterized Pantoea agglomerans surfactant. Introduction . Bacterial growth at −15 °C; molecular insights from the permafrost bacterium Planococcus halocryophilus Or1 N. Mykytczuk , S. Foote , Chris R. Omelon , G. Southam , … Planococcus sp. 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. The Planococcus sp. 16S rRNA gene sequencing analysis of the bacterial isolates identified species from several genera, including Halomonas, Bacillus, Kushneria, Virgibacillus, Planococcus, Pseudomonas, and others. 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. Planococcus Species – Untapped Marine Resource for the Production of Biosurfactant and Other Metabolites. The culture supernatant after 72 h showed reduction in … Twelve of the isolates, which were coccoid in shape, were very similar and possessed all the characteristics of the genus Planococcus and represented … Planococcus citri is a highly polyphagous, adaptable mealybug that can feed on many host plants in a variety of conditions, and can reproduce rapidly. Formation of froth indicating the surfactant production was observed when grown in basal salt medium containing 2% glucose. Micrococcus are aerobic, Gram-positive cocci ranging in size from 0.5 to 2.0 μm in diameter. Therefore, we regard these strains as belonging to a new genus, and propose the genus Marino-coccus for such bacteria. Quorum quenching (QQ) is the disruption of bacterial cell-to- cell communication (known as quorum sensing), which has previously been described in mesophilic bacteria. Five strains were regarded as belonging to a new species in the genus Planococcus, and Planococcus kocurii Hao and Komagata sp. Because of the above properties, Planococcus exhibited a potential capability in the bioremediation of extremely contaminated environments. Each isolate … A gene encoding a beta-galactosidase in this isolate was cloned in an Escherichia coli host. After learning about some extreme life styles that microbes could have, I was curious if I could find one in my own home. Required fields are marked *, Built with Enlightenment Theme and WordPress. Two species are recognized in this genus, Marinococcus albus sp. These characteristics differ significantly from those of the type species (Planococcus citreus) of the genus Planococcus. be applied to all the bacterial genus [6–8].
