Abstract
The production ofl(+)-lactic acid and formation ofγ-linolenic acid by 50Rhizopus strains growing on saccharidic substrates were investigated. Formation of acids was observed on solid cultivation media but mainly during submerged fermentation. Strains with the highest selectivity of bothl(+)-lactic acid production andγ-linolenic acid formation were tested in a laboratory fermenter. The best producer was treated by UV irradiation to increase the fatty acid content in the biomass, especially that ofγ-linolenic acid. The conversion of 10% saccharidic substrate by this newly prepared strainRhizopus arrhizus CCM 8109 results in more than 95% of theoretical yield ofl(+)-lactic acid and permits a volume productivity of 0.4 gγ-linolenic acid per liter.
