Therefore, we regard these strains as belonging to a new genus, and propose the genus Marino-coccus for such bacteria. 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. The biosurfactant production of Planococcus citreus was 2.014 g/L, more than twice the Pantoea agglomerans production, which was 0.87 g/L. The main characteristic of Planococcus citreus surfactant was the formation of oil-in-water emulsions, while water-in-oil emulsions characterized Pantoea agglomerans surfactant. 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. Despite having such old history, Planococcus was not reported in the public domain validly for several years.Kocur et al. Bacteria were isolated from the rhizosphere and as root endophytes associated with Salicornia rubra, Sarcocornia utahensis, and Allenrolfea occidentalis, three native Utah halophytes. Isolated from sub-artic decomposing wood. Planococcus sp. Introduction . Planococcus sp.

Thirteen orange-pigmented bacteria associated with cyanobacterial mat samples collected from four different lakes in McMurdo, Antarctica, were isolated. This assignment is consistent with the morphology and physiological characteristics of the organism. Morgen Southwood April 26, 2017 . The soil Bacterial survival in salty antifreeze raises hope for life on Mars and icy moons. The traditional phenotypic tests are commonly used in actinobacterial identification. Although many studies have reported the genomic backgrounds of Planococcus … Extracted pigments from cold-adapted bacteria showed multiple absorption peaks between 400-550 nm, characteristic of carotenoid pigments11,12. Characteristics. 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. The classical phenotypic characteristics of actinobacteria comprise morphological, physiological, and biochemical features. nov. and Marinococcus halophilus (Novitsky and Kushner) comb. The culture supernatant after 72 h showed reduction in … Formation of froth indicating the surfactant production was observed when grown in basal salt medium containing 2% glucose. The structural characteristics of the strain Y42T genome provided a competitive advantage for better survival in petroleum-polluted environments. nov. (CMS … Herein, we describe the complete genome sequence information of the genus Planococcus with its annotated sequence, genetic features for bioremediation, and oxidative stress capacity. Strain Y74 T was an isolate from the sandy soil in the town of Huatugou, Qinghai–Tibet Plateau, China. 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. Planococcus is a Gram-positive, psychrotolerant, halophilic bacterium, which was initially proposed by Migula (1994) in 1894. Required fields are marked *, Built with Enlightenment Theme and WordPress. 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]. These characteristics differ significantly from those of the type species (Planococcus citreus) of the genus Planococcus.
