Comparative genomic analysis of Mycobacterium neoaurum MN2 and MN4 substrate and product tolerance.

ABSTRACT: The microbial bioconversion of sterols can afford valuable steroid precursors, such as 4-androstene-3,17-dione (AD) and androsta-1,4-diene-3,17-dione (ADD). The Mycobacterium neoaurum MN4 mutant strain can produce AD in high yield and can tolerate a higher concentration of the substrate phytosterol than the parent strain M. neoaurum MN2. In order to further investigate the mechanisms underlying the enhanced substrate and product tolerance, we performed a genomic analysis of the MN2 and MN4 strains. The genomes were sequenced using a high-throughput approach and analyzed using software for genome assembly, gene prediction and functional annotation, KEGG (Kyoto Encyclopedia of Genes and Genomes) annotation, COG (cluster of orthologous) group cluster analysis, GO cluster analysis, and SNP det
