Efficient Bioproduction of 5-Aminolevulinic Acid from Low-Cost and Sustainable Bioresources of Corn by Engineered Corynebacterium Glutamicum

SSRN Electronic Journal (2022)

5-Aminolevulinic acid (5-ALA) has drawn intensive attention owing to its potential applications in agriculture, medicine and other fields, but the high production cost limits its large-scale application. Cheap and renewable biological resources all derived from corn was used to lower the cost in the study. Pretreated corn steep liquor was an ideal alternative to yeast extract in that the final 5-ALA titer reached 1.46g/L at dosage of 15g/L, which was 22.07% higher than that of the yeast powder group. Notably, pretreated corn gluten meal was also a good substitute for yeast extract, and replacing yeast extract with the above feedstocks will reduce the nitrogen source cost by 91.95% and 84.38%, respectively. Furthermore, strain A6 exhibited different growth forms during the fermentation process, which was related to the production of 5-ALA. This may provide basis for studying the mechanism and regulation mechanism of bacterial growth and fermentation production of 5-ALA.
