摘要

The effect of dried potato peels after acid hydrolysis (potato peel hydrolysate- PPH) supplementation on the mycelial growth and citric acid production of Aspergillus nigerCA16 was examined inmediumcontaining sucrose and Prescott salt. In shake flask studies, addition of PPH resulted into 6-fold increment in biomass and 5 fold increment in citric acid production at 13th day of fermentation. Supplementing PPH, therefore, can not only reduce fermentation media cost by replacing Prescott salt but also can be used along with Prescott salt for the enhanced production of citric acid from sucrose.
