The actinomyceteMicromonospora chalcae produces a chitinolytic system following growth on chitin containing medium. When the organism was co-immobilized in calcium alginate, the amount of chitinase produced was 2-fold higher than the levels produced by the free system. When the immobilized organism was used in a batch fed reactor system it was capable of producing much more enzyme than the free system.
