Study on the Scaling-up of Acarbose Fermentation Processes
摘要
Abstract
The scale-up strategy for acarbose fermentation by Actinoplanes sp. A-56 was explored in this paper. The results obtained in shake-flask cultivation demonstrated that the ratio of maltose and glucose had significant effect on acarbose biosynthesis, and the feeding medium containing 3 : 1 ( mass ratio) of maltose and glucose was favorable for acarbose production. Then the correlation of carbon source concentration with acarbose production was further in- vestigated in 100 L fermenter, and the results showed that 75 - 80 g/L of total sugar and 40 -45 g/L of reducing sugar were the optimal for acarbose production. Based on the results in 100 L fermenter, an effective and simplified scale-up strategy was successfully established for acarbose fermentation in a 30 m^3 fermenter by using total sugar and reducing sugar as the scale-up parameter. As a result, 4 327 mg/L of acarbose was obtained at 168h of fermentation.关键词
