assay at, levan formation reaches the highest value at 4°C and 100 g/l sucrose. The increase of temperature to 40°C and fructose concentration of 600 g/l causes a significant decrease of the levan concentration and a higher production of short-chain fructooligosaccharides, an increase of the temperature also causes an enhancement of hydrolytic activity
