Relation of bacteria of the genus Pedicoccus to temperature and acidity of the medium

Hosseinnejat Siruz Sulduz  (Doctoral student, Baku State University)

This work aimed to study the effect of temperature and acidity (pH) of the medium on the growth of lactic acid bacteria of the genus Pedicoccus isolated from the phyllosphere of fruit trees. It was shown that all studied bacteria actively grow in the temperature range of 300C, and the maximum growth occurs at 350C. Intensive bacterial growth was observed at a pH of 5-6, however, the types of bacteria differed in the optimum acidity point. Thus, the optimum acidity of the medium for the development of bacteria Pedicoccus acidilactici BDU21 and P. pentosaceus BDU32 is pH 5.5, for P. halophilus BDU42 - pH 6.0, and P. cerevisae BDU11 - pH 5.5-6.0. Consequently, the studied species of bacteria of the genus Pedicoccus had the same attitude to temperature but differed in the optimal acidity (pH) of the medium.

Keywords:lactic acid bacteria, Pedicoccus, temperature acidity (pH) of the medium, bacterial growth.
