the bacterium oceanimonas sp. (o. sp.) gk1 is a member of the aeromonadaceae family and its genome represents several virulence genes involved in fish and human pathogenicity. in this original research study we aimed to identify and characterize the putative virulence factors and pathogenicity of this halotolerant marine bacterium using genome wide analysis. materials and methods: the genome da...

A Gram-stain-negative, motile, non-spore-forming and short rod- or rod-shaped bacterial strain, T-w6(T), was isolated from seawater of an oyster farm in the South Sea, Korea. Strain T-w6(T) grew optimally at 25 °C and in the presence of 2% (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain T-w6(T) joined the cluster comprising Oceanisphaera species with a bo...

In total, 140 halotolerant bacterial strains were isolated from both the soil of barren fields and the rhizosphere of six naturally growing halophytic plants in the vicinity of the Yellow Sea, near the city of Incheon in the Republic of Korea. All of these strains were characterized for multiple plant growth promoting traits, such as the production of indole acetic acid (IAA), nitrogen fixation...

Hydraulic fracturing is a method of oil and gas extraction from shale in which substantial volumes of water return to the surface containing chemicals and microorganisms. This paper begins to address the microbial composition and aqueous chemistry and the potential for intrinsic and enhanced bioremediation of these waters. The waters from a gas and oil shale in the Marcellus and Bakken regions,...

l-asparaginase is a candidate enzyme for anti-neoplastic agent againstacute lymphoblasticleukemia and also extensively use in the food industry for prevention of acrylamide formation. l-asparaginase is widely distributed among microorganisms. in this study, marine bacteria were isolated from persian gulf and screened for l-asparaginase activity. production of l-asparaginase was carried out by u...
