M. Berrocal et al., EFFECT OF WATER ACTIVITY ON CELL-GROWTH AND PHENOL OXIDASE PRODUCTIONBY STREPTOMYCES-CYANEUS VAR VIRIDOCHROMOGENES IN SURFACE CULTURE, World journal of microbiology & biotechnology, 12(1), 1996, pp. 101-102
In surface cultures of Streptomyces cyaneus var. viridochromogenes, Na
Cl depressed water activity (a(w)) without supporting growth. Reducing
a(w) from 0.987 to 0.951 led to 3- and 8-fold increases in intracellu
lar and extracellular phenol oxidase activities, respectively.
