AcrAB-TolC is a major efflux pump in Escherichia coli. It was reported that tolC is overexpressed and involves in improving the organic solvent tolerance level in Escherichia coli marR mutants that are resistant to several antibiotics, such as ciprofloxacin. Low and intermediate levels resistance did not improve organic solvent tolerance. Thus, in this descriptive-experimental study it was deci...

conclusions in this study, we isolated b. licheniformis producing an organic solvent-stable protease from oil-contaminated soil. the protease was stable and active in various organic solvents. by purification, the protease could be used as a biocatalyst for organic solvent-based enzymatic synthesis. results according to 16srdna sequencing, strain isa9 was identified as a new strain of bacillus ...

The present paper reports an organic solvent-induced controllable crystallization of a water-soluble inorganic salt Na(3)[Au(SO(3))(2)] into ultralong nanobelts and hierarchical microstructures of one-dimensional (1D) nanowires. It was found that the morphology of the resulting crystals can be fine tuned by simply varying the experimental parameters, such as the ratios of water to organic solve...

Organic-solvent tolerance in Saccharomyces cerevisiae strain KK-211, which was first isolated as an organic-solvent-tolerant strain, depends on point mutation (R821S) of the transcription factor Pdr1p. The integration of the PDR1 R821S mutation into wild-type yeast results in organic-solvent tolerance, and the PDR1 R821S mutant can reduce carbonyl compounds in organic solvents.

AcrAB-TolC is a major efflux pump in Escherichia coli. It was reported that tolC is overexpressed and involves in improving the organic solvent tolerance level in Escherichia colimarR mutants that are resistant to several antibiotics, such as ciprofloxacin. Low and intermediate levels resistance did not improve organic solvent tolerance. Thus, it was decided to measure tolC expression and organ...

using enrichment procedures, 45 organic solvent-tolerant lipase producer bacterial strains were screened from areas contaminated by oil and organic solvents. among the strains, 15 isolates exhibited extreme stability toward organic solvents and high lipolytic activity. the neb-1 isolate which was later identified as   pseudomonas sp. strain neb-1 by biochemical tests and 16s rdna gene sequ...
