[Advance in dihydroxyacetone production by microbial fermentation].

We reviewed the fermentation for dihydroxyacetone production. Microbial fermentation is better for dihydroxyacetone production as compared to chemical methods. Gluconobacter oxydans was recognized as the most important strain for industrial production of dihydroxyacetone. The dihydroxyacetone yield is associated with many factors such as substrate, product, oxygen and biomass concentration. Repeated fed-batch fermentation and immobilization fermentation were recognized as the most potential process in various fermentation mode. Construction of recombinant microorganism and optimization of process are future directions of dihydroxyacetone production.
