  • Title: [Various physiological aspects of Serratia marcescens pigmented strains and their pigmentless variants with an elevated nuclease activity].
    Author: Porfir'eva OV, Iusupova DV, Beliaeva MI.
    Journal: Mikrobiologiia; 1976; 45(6):1045-8. PubMed ID: 189164.
    Abstract:
    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.
