Spore differentiation in relation to certain antibiotics in the blue-green alga Nodularia spumigena Mertens
Abstract
Induction of spore differentiation is achieved within three days in Nodularia spumigena by incubating the cultures at 35 degrees C in the light. Morphologically detectable sporulation and spore germination could not occur in the presence of chloramphenicol, streptomycin and penicillin. But chloramphenicol-supplemented cultures developed prominent cyanophycin granules. Synthesis of these granules seems to be a non-ribosomal phenomenon.
