[Growth and spore formation in Bacillus thuringiensis at high substrate concentrations]. 1988

Z V Sakharova, and I L Rabotnova, and M P Khovrychev

The work was aimed at studying the effect exerted by elevated concentrations of glucose, yeast extract and acetate on the growth of Bacillus thuringiensis subsp. galleriae, strain 69-6, and on the formation of spores and crystals by it. Glucose concentrations from 30 to 100 g per litre did not prevent spore formation. Yeast extract inhibited spore formation to a greater extent and stopped it almost completely at a concentration of 20 g per litre. Acetate at a concentration of 1.0 to 10 g per litre delayed spore formation and produced a less action on crystal formation, so that those processes were uncoupled in time.
