| Efficient 1,3-dihydroxyacetone biosynthesis in Gluconobacter oxydans using metabolic engineering and a fed-batch strategy |
To enhance 1,3-Dihydroxyacetone (DHA) production, the G. oxydans WSH-003 strain was selected from five industrial wild-type strains. By knocking out individual dehydrogenase genes unrelated to DHA synthesis, a suite of engineered strains was constructed. The G. oxydans WSH-003–4 strain yielded 89.49 g L−1 DHA, enhancing production by 42.27%. By optimizing culture media in flasks, DHA production was further enhanced, while the addition of organic nitrogen source in culture media was decreased. Furthermore, using an intermittent fed-batch fermentation strategy, 198.81 g L−1 DHA was generated in a 5 L bioreactor, with a glycerol conversion rate of 82.84%. We provide a reference point for the industrial production of DHA and other chemicals using Gluconobacter. , Bioresources and Bioprocessing volume 9, Article number: 121 (2022) |
| Novel Process for 1,3-Dihydroxyacetone Production from Glycerol. 1. Technological Feasibility Study and Process Design |
A novel and efficient conversion process of glycerol to 1,3-dihydroxyacetone (DHA) via indirect oxidation was developed. The idea is to oxidize the middle hydroxyl group of glycerol to a carbonyl group with the help of a group protection technique, and then the protection reagent is removed by hydrolysis. With this new process, the conversion is conducted in three steps, namely, acetalization, oxidation, and hydrolysis. The oxidation step is the focus of this conversion process. , Ind. Eng. Chem.
