摘要

Simultaneous isomerisation and fermentation (SIF) of xylose and simultaneous isomerisation and cofermentation (SICF) of a glucose/xylose mixture was carried out by Saccharomyces cerevisiae in the presence of xylose isomerase. The SIF of 50 gl(-1) xylose gave an ethanol concentration and metabolic yield of 7.5 gl(-1) and 0.36 g (g xylose consumed)(-1). These parameters improved to 13.4 gl(-1) and 0.40 respectively, when borate was added to the medium. The SICF of a mixture of 50 g l(-1) glucose and 50 g l(-1) xylose gave an ethanol concentration and metabolic yield of 29.8 g l(-1) and 0.32 respectively, in the presence of berate. Temperature modulation from 30 degrees C to 35 degrees C during fermentation further enhanced the above parameters to 39 gl(-1) and 0.45 respectively. The approach was extended to the bioconversion of sugars present in a real lignocellulose hydrolysate (peanut-shell hydrolysate) to ethanol, with a fairly good yield. [References: 17]
