[Chemotaxis of Bacillus subtilis toward organic compounds]
Abstract:
New data about chemotaxis properties, including trophic taxis of Bacillus subtilis IMV B-7023 toward some amino acids, carbohydrates and organic acids was described. The chemotaxis of this strain differed from one of the studied before Bacillus subtilis both by intensity and by the type of reaction. The chemotaxis reaction and trophic taxis to majority of investigated effectors were compared. The trophic taxis to attractants of inositol and sorbitol were absent. Serine and citric acid were either repellents or attractants, depending on the concentration, and rhamnose and dulcitol were neutral effectors.
