Abstract:

Serratia marcescens was grown on cell wall of Sclerotium rolfsii and its components, chitin and laminarin, as a sole carbon source. A culture filtrate, possessing chitinolytic activity, was obtained and incubated with different substrates, including S. rolfsii cell wall, dry mycelium, and washed mycelium. A release of N-acetyl-d-glucosamine at rates of 1x5.2 chitinase units indicated substrate degradation. Degradation of hyphae of the plant pathogen was observed by light and scanning electron microscopy. Crude chitinase caused very swift swelling at the hyphal tips of the fungus. Sixty-three percent of the cells of the hyphal tips lysed.
