dc.description.abstract | A new bacterium producing a novel transfructosylating enzyme was isolated from soil and designated as Bacillus macerans EG-6. Various culture conditions for enzyme production were optimized in a flask culture. 1% (w/v) sucrose as a carbon source and a mixed nitrogen source (1% yeast extract, 1% polypeptone, and 0.5% ammonium chloride) gave the best enzyme production. Addition of phosphate and magnesium ion into the medium enhanced the enzyme yield. Optimum culture pH and temperature were 7.0 and 37°C, respectively. Under optimal culture conditions, transfructosylating enzyme was rapidly produced in the early growth period, thereafter invertase activity was predominant as the culture proceeded. Using the culture filtrate, production of fructooligosaccharides from sucrose was preliminarily carried out. In a low sucrose concentration (200 g/l), transfructosylating activity competes with invertase activity in sucrose utilization. Subsequently, low fructooligosaccharide yield (20%) was achieved due to liberation of high amounts of glucose and fructose. The best oligosaccharide yield (43%) was achieved when 500 g/l sucrose was utilized. | - |
