Abstract

Galactosidase and proteolytic activity of lactic acid bacteria, of DELVO-YOG series is investigated. It is established that DELVO-YOG lactic acid bacteria have the maximum galactosidase activity when the CMC Akutsel 2785 is used as a stabilizer, and the minimum activity when sodium alginate NO4-600 is used as a stabilizer. It is found that DELVO-YOG lactic acid bacteria have the maximum proteolytic activity when sodium pyrophosphate SAPP 28 is used as a stabilizer. The minimum proteolytic activity of DELVO-YOG lactic acid bacteria is revealed when using CMC 6000-9000 stabilizer. It is noted that with increasing the mass fraction of the stabilizer from 0,5 to 1,0 %, an increase in galactosidase and proteolytic activity of all kinds of DELVO-YOG lactic acid bacteria occurs.
