Abstract: | The production of lytic enzyme by Streptomyces thermodiastaticus was found to be affected by some growth conditions and nutritional factors. The highest enzyme production was obtained after 18 h of incubation at pH 5.5 and at 50 degrees C. The carbon source influenced the lytic enzyme production. A higher enzyme yield was obtained when Candida albicans cell wall (1 g/100 ml) was used as the sole carbon source. NaNO3 at 0.1 g/100 ml was the best nitrogen source for enzyme production. From all phosphorous sources, microelements, and growth factors tested, KH2PO4 (1 g/l), ZnSO4 (1 mg/I) and Tween 80 (0.1%), respectively, were found to favour the highest production of lytic enzymes by S. thermodiastaticus. The lytic enzymes mainly produced chitinolytic and proteolytic activities. |
