[Various physiological aspects of Serratia marcescens pigmented strains and their pigmentless variants with an elevated nuclease activity].

Some aspects of physiology of Serratia marcescens pigmentless variants with elevated nuclease activity were studied. The variants are characterized by a higher respiration rate when glucose, glycerol, inositol or maltose are used as an energy substrate, a higher respiration quotient, a lower growth rate, a lower economic coefficient, and a lower thermogenesis. The growth of Serratia marcescens pigmentless strains is presumed to be unbalanced.
