LIPASES BACTERIA ACTIVITY OF GENUS BACILLUS

Abstract

There have been screened the producers of exsolyases among 353 strains of bacteria of genus Bacillus. There has been shown that 62.1% of strains of Bacillus are capable of hydrolysing of olive oil and twins. B. subtilis, B. licheniformis, B. cereus and B. megaterium hydrolyzed these substrata the most actively. This ability was absent at B. brevis, B. bombycis, B. lentus. However only 19.5% of strains hydrolyzed olive oil. Four groups of bacteria strains were identified on the basis of different substrate specificity. The third group – strains, capable of hydrolysing of twins and olive oil, and the fourth group – strains, capable of hydrolysing only olive oil are the most perspective and the most productive. There has been shown that olive oil in concentration of 0.5% is capable of stimulating growth and biomass accumulation of bacteria, but inhibiting lipases activity. Synthetic twins influenced on the activity of lypases of bacteria ambiguously: at one strains it was stimulated, at others – inhibited.
