摘要
报道了酵母属间融合菌株F2 7利用菊粉进行山梨醇发酵适宜条件的研究结果。其适宜的发酵培养基组成为 (% ) :菊粉 (以总糖计 ) ,10 ;酵母膏 ,2 .5 ;葡萄糖 ,1.0 ;MnSO4 ,0 .1。适宜的发酵条件为 :培养基初始 pH5～ 6 ,接种量 10 % (V/V) ,温度 35℃。该菌株经摇瓶发酵 72h后 ,山梨醇产量可达 4 .87g/ 10
The optimum conditions for sorbitol production from Jerusalem artichoke by a yeast fusant F27 were investigated. The suitable medium for the sorbitol production was composed of 10% inlulin(total sugar), juice, 2.5%yeast extract and 1.0% glucose. The optimum cultivation temperature and initial pH for the sorbitol production were 35℃ and 5～6 respectively. Under these conditions, a maximum sorbitol production of 4.87 g/100mL was obtained after 72 hours of growth in shake cultures.
