Solid-state fermentation (SSF) is one of the oldest biotechnological processes in China.With the development of SSF, and the advantages of SSF vs SmF such as low water demand,higher fermentation productivity, higher end-concentration of products, higher productstability, lower catabolic repression, SSF attracted world wide attention for the production ofbioactive metabolites and environment control. Comparative study showed that SSF couldbear higher concentration of substrate and relieve catabolic repressio...
