Аннотация:In a mixed batch culture, Alcaligenes xylosoxidans subsp. xylosoxidans 260 transformed maleic acid into malic acid. Bacillus subtilis 271 used malic acid as a substrate, thus stimulating further transformation of maleic acid. Both bacterial cultures dissociated with the formation of R, S, and M forms. At a concentration of 5.0 g/l, maleic acid was utilized maximally by RS and SS forms of the association A. xylosoxidans and Bacillus subtilis. At concentrations 15.0 and 25.0 g/l, maleic acid was utilized maximally by SS and MS forms of the mixed culture, respectively. Association of bacteria A. xylosoxidans and B. subtilis was not stable under flow conditions water.
