Induction of bacteriophage in lactic streptococci

U osam sojeva koji pripadaju vrstama S. lactis i S. lactis subsp. diacetylactis istraživano je prisustvo bakteriofaga primjenom UV zračenja i mitomycina C (MC). Pod uticajem različitih doza indukcionih sredstava kod pet sojeva je došlo do indukcije profaga. Nijedan od istraženih sojeva nije pokazao indikatorska svojstva. U radu je također istaknut značaj lizogenih bakterija za odabir sojeva koji ulaze u sastav startera.Eight strains of lactic streptococci were examined for lysogeny by treatment with ultraviolet light and Mitomycin C. Induction of lysis in five strains de-mostrated what lysogenic state is very common in lactic streptococci. No one indicator strain has been found. The possible significance of lysogeny for cheese making practice has been discussed
