| Abstract: | Starch induces Myxococcus coralloides to secrete amylase. Amylase production has been observed during various stages of the life cycle of this myxobacterium both in liquid and solid media. Secretion was very high during vegetative growth at the end of the exponential growth phase in all media. During myxospore formation (glycerol-induced and fruiting-body formation) amylase activity decreased and finally ceased in the mature myxospores. During germination of glycerol-induced myxospores and fruiting-body myxospores a progressive increase in this activity was observed. |
