Abstract:

The sisomicin production was found to be non-associated with the cell growth of M. inyoensis F003. When starch was used as main carbon source, the maximal specific growth rate was 0.058 h-1, and the maximal specific sisomicin production rate was 0.0018 g/(g-h). The cells of M inyoensis F003 grew well at 10.0-25.0 g/L maltose or 7.5-15.0 g/L glucose in fermentation broth. It was shown by HPLC analysis and enzymatic measurement that maltose was the main fermentable sugar during the fermentation, and sisomicin biosynthesis was limited when the level of fermentable sugar was below 10.2 g/L. The apparent activity of starch-hydrolytic enzymes in the batch fermentation of M inyoensis F003 was 1/4 to 1/20 fold of the maximum value 0.84 g/(L-h) in sisomicin biosynthesis phase, its apparent activity, which would result in restriction to the sisomicin biosynthesis by the limitation of fermentable sugar in the broth. Sisomicin above 0.5 g/L was inhibitive to its biosynthesis.
