title: Calcium ion regulates aerial mycelium formation in actinomycetes.
abstract: Ca2+ induced the formation of aerial mycelia in Streptomyces ambofaciens. Its effect was inhibited by ethylene glycol bis(beta-aminoethyl ether)-N,N,N',N'-tetraacetic acid, a Ca2+ specific chelating agent. A survey of 36 strains of actinomycetes showed that Ca2+ regulated aerial mycelium formation in 21 (58%) of them. The Ca2+ concentration required for aerial mycelium formation in the culture medium ranged from 0.1 to 1.5 mM.
