Further Information

Fermentation is ‘activity of life’ itself, and thus, is veiled in mystery. Much remains to be elucidated. Our aim is to clarify the mystery of fermentation with the help of genomics. Then, hitherto unknown mechanisms for fermentation may emerge, which will provide new and valuable insights into strategies of strain development and will lead to the exploitation of innovative fermentation processes. Toward this goal, we will firstly investigate the physiology and genome of producer organisms to address the molecular mechanism of high-level production and also the genetic basis restricting the performance of the organisms. Secondly, we will apply the information to extend the performance of producer strains as well as to develop new methodology not only for ‘metabolic engineering’ but also for ‘physiologic engineering’. We will also direct our eyes not only to water-soluble metabolites but also to water-non-soluble lipid for the development of bacterial strains excreting lipid.
