[Dynamics of accumulation of extracellular lipoteichoic acid in Bacillus cereus].
The dynamic of accumulation of extracellular lipoteichoic acid (LTA) was studied depending on the growth stage of Bacillus cereus st. 96. A maximum amount of extracellular LTA was detected in the middle of the exponential growth. The quantity of the biopolymer present in the culture medium at the beginning of the stationary growth under conditions of catabolite repression of sporulation and without repression was found to be different. Experimentally increased concentrations of LTA inhibited B. cereus sporulation. Besides, dormant spores of B. cereus st. 96 were found to contain LTA.
