[The effect of the cultivation conditions on lectin production by representative bacteria in the genus Bacillus].

Dynamics of the lectin activity accumulation in the culture liquid was studied through the example of certain representatives of spore-forming aerobic bacteria in the process of their growth. The environmental factors (the temperature, pH value, the presence of definite carbohydrates in the medium) were investigated for their effect on the biosynthesis of extracellular lectins by producers. Based on these studies it was possible to establish optimal conditions of cultivation and to obtain the high specific lectin activity of the culture liquid for each strain.
