A rapid method to screen degradation ability in chlorophenoxyalkanoic acid herbicide-degrading bacteria.

abstract：:Ergosterol biosynthesis in Saccharomyces cerevisiae is complex and the underlying mechanism of regulation remains unclear. To clarify the influence of transcriptional regulation on the ergosterol content, transcription factor Ecm22 was overexpressed in S. cerevisiae. Results showed that the overexpression of ECM22 led...
