摘要: Summary The production of extracellular inulinase by eighteen Thermomyces lanuginosus strains was screened, and strain IMI 140524 selected for further studies. effects various carbon nitrogen sources on activity were investigated, the best ones found to be Jerusalem artichoke extract peptone at optimum fraction 1.8 0.6 %, respectively. Effects medium composition fermentation conditions also determined inulinase. addition 1 % (by volume) Tween 80 into enhanced secretion In bench-scale fermentor, age amount inoculum optimized they 40-hour-old culture 5.0 volume), initial pH adjusted 6.5 no control needed. Optimal aeration agitation 0.75 L/min 150 rpm,
