Effects of Oxygen Supply on Microbial Xylitol Production from Corn Cobs by Candida Magnoliae

Abstract

The effects of oxygen supply on microbial xylitol production from corn cobs using Candida magnoliae were investigated. The xylitol production by C. magnoliae was strongly influenced by oxygen supply during fermentation and the successful xylitol production occurred only when the oxygen transfer rate (OTR) into a fermentor ranged from 1.6 mmol-O₂/L/h to 4.7 mmol-O₂/L/h. The maximum xylitol yield of 0.6 was obtained at an OTR of 1.6 mmol-O₂/L/h.
