  • Title: Effect of temperature, salts, pH, and other factors on the development of peritrichous flagella in Vibrio alginolyticus.
    Author: Ulitzur S.
    Journal: Arch Microbiol; 1975 Aug 28; 104(3):285-8. PubMed ID: 242290.
    Abstract:
    The development of peritrichous flagella and, consequently, swarming of Vibrio alginolyticus depend on a complex relationship between temperature, salt concentrations and pH. At temperatures above 28 degrees C V. alginolyticus did not develop peritrichous flagella unless certain minimal concentrations of NaCl are present: the higher the temperature, the higher the NaCl concentrations required for peritrichous flagella synthesis. This requirement for NaCl at high temperatures is much more pronounced at pH 9 than at pH 6. High temperatures and low concentrations of NaCl also inhibited swarming of cells already armed with peritrichous flagella. Other cations, such as Li+, K+ and Mg2+. replaced NaCl only at temperatures below 28 degrees C.
