title: Short communication: Effect of water activity on cell growth and phenol oxidase production by Streptomyces cyaneus var. viridochromogenes in surface culture.
abstract: In surface cultures of Streptomyces cyaneus var. viridochromogenes, NaCl depressed water activity (a w) without supporting growth. Reducing a w from 0.987 to 0.951 led to 3- and 4-fold increases in intracellular and extracellular phenol oxidase activities, respectively.
