Objectives . To isolate biosurfactants of glycolipid nature produced by oil hydrocarbon degrading bacteria and to establish their ability solubilize hydrophobic compounds in the case n-hexadecane. Methods Trehalolipids were isolated from Rhodococcus erythropolis X5 (VKM Ac-2532 D) S67 Ac-2533 included MikroBak biopreparation for bioremediation oil-contaminated territories. The genome R. is deposited National Center Biotechnology Information database under GenBank accession numbers CP044283...
Gordonia amicalis G2 strain is a potential object for the production of microbial glycolipids using oil refinery wastes. The genome G. consists ring chromosome and plasmids pCP113 pCP89. Bioinformatic analysis showed availability enzymes involved in synthesis fatty acids trehalose, which form structure biosurfactants.
N this study it was reported, that significant biosurfactants produced by Rhodococcus sp. X5 grown on n-hexadecane, are succinoyl trehalose tetraesters. The structural characterization of trehalolipids determined based MS/MS and GC/MS analysis. Succinoyl from exhibit high surface activity (27 mN/m) emulsifying (E 24 - 55%). Biosurfactants were characterized the next physico-chemical indications minimum tension mN/m), critical micelle concentration (4,1·10 -5 mol/l),hydrophilic lipophilic...
During the experiments conducted, it was shown that actinobacteria of genus Rhodococcus are able to grow on hard-toreach substrates regardless its aggregate state. When oxidants added incubation medium, activity antioxidant enzymes increases, as more ROS formed. The strain R. erythropolis S67 has significantly high values enzyme activity, which makes stable in presence oxidants.
The article describes current concepts of mechanisms the formation biofilms - a supracellular colonial prokaryotic form microorganisms causing infectious urogenital pathologies. authors describe role signal molecules and extracellular genetic material for biofilm as well synergy antagonism between different types bacteria. presents possible existence prokaryotes torpidity to therapy resulting in longterm chronic infection.
