A process for producing epsilon-poly-L-lysine.

摘要

An effective process for producing epsilon -poly-L-lysine is provided, which process comprises cultivating a microorganism having epsilon -poly-L-lysine productivity such as a bacterium belonging to Streptomyces genus in the form of immobilized bacterial cells under aerobic conditions, and according to which process, the bacterial cells cause no bacteriolysis; the immobilized bacterial cells retaining epsilon -poly-L-lysine productivity can be easily separated and recovered from the culture solution containing epsilon -poly-L-lysine; and further a semi-continuous or continuous production of epsilon -poly-L-lysine by the use of the immobilized bacterial cells is possible.
