STUDY OF INFLUENCE OF THE pH MEDIUM ON SYNTHESIS OF BACTERIOCIN-LIKE INHIBITORY SUBSTANCES AND GROWTH DYNAMICS OF STRAIN LB. PARACASEI SPP. PARACASEI BN ATS 5W
Abstract
The aim of this work was to study the effect
of different pH values (pH 4.5, 5.5, 6.5) on the synthesis of
bacteriocin-like inhibitory substances (BLISs) and growth dynamics
of the producer strain Lb. paracasei spp. Paracasei
BN ATS 5W. The test strain was isolated from the traditional
cheese Absheron, produced in Azerbaijan. As a result, it
was found that the optimal pH for the growth and accumulation
of an antimicrobial agent in the culture medium is pH 5.5.
Under low pH values (pH 4.5) the growth of studied strain
cells became slow. Weakly acidic pH values (pH 6.5) led to a
decrease in the antimicrobial activity.
