| optimization and characterization of a new lipopeptide biosurfactant produced by marine brevibacterium aureum msa13 in solid state culture. | the biosurfactant production of a marine actinobacterium brevibacterium aureum msa13 was optimized using industrial and agro-industrial solid waste residues as substrates in solid state culture (ssc). based on the optimization experiments, the biosurfactant production by msa13 was increased to threefold over the original isolate under ssc conditions with pre-treated molasses as substrate and olive oil, acrylamide, fecl(3) and inoculums size as critical control factors. the strain b. aureum msa13 ... | 2010 | 19959354 |

| characterization of a novel cyfluthrin-degrading bacterial strain brevibacterium aureum and its biochemical degradation pathway. | brevibacterium aureum dg-12, a new bacterial strain isolated from active sludge, was able to degrade and utilize cyfluthrin as a growth substrate in the mineral medium. response surface methodology using central composite rotatable design of cultural conditions was successfully employed for optimization resulting in 88.6% degradation of cyfluthrin (50mgl(-1)) within 5days. the bacterium degraded cyfluthrin by cleavage of both the carboxylester linkage and diaryl bond to form 2,2,3,3-tetramethyl- ... | 2013 | 23395753 |
