How does the pH of the culture medium affect the production of dihydroxyacetone (DHA)?

Label:chem

Topic
The pH of the culture medium is a critical factor in microbial fermentation processes, influencing the metabolic activity of the bacteria.
Answer
The optimal pH for the production of dihydroxyacetone (DHA) using Gluconobacter oxydans LMG 1385 is 5.0. At this pH, the highest final concentration of DHA (175.8 g·L−1) and the highest yield (94.3%) were achieved. A pH of 6.0 resulted in lower DHA concentrations and yields.
