    Biochemical factors ınfluencing autolysis of leuconostocs in buffer
    (Uludağ Üniversitesi, 2010-07-12) Çıbık, Recep; Uludağ Üniversitesi/Veteriner Fakültesi.
    Factors influencing autolysis of two dairy leuconostocs strains chosen for their moderate and relatively higher autolytic extend were investigated in buffer system. Higher level of autolysis was observed in bacteria that were harvested at earlier exponential phase. Autolysis was greatly influenced in acidic and basic pH values and optimal level was monitored between 6 and 7 values. Optimal incubation temperature to induce lysis was detected at 30°C, which is at the same time optimal growth temperature for leuconostocs strains. Whereas autolysis was activated by the presence of monovalent cations, an important level of inactivation was noted in the presence of divalent cations.
