Resumo: | Penicillium purpurogenum was found to produce both extracellular and intracellular fructosyltransferase. The organism could also produce sucrose hydrolytic enzyme. Sucrose was found to be the best carbon source for fructosyltransferase production. Maximum intracellular and extracellular fructosyltransferase production was observed after 3rd and 4th day of cultivation, respectively. The enzyme activity was optimum at temperature of 55ºC and pH 5.5. The addition of amino acids, like leucine induced slightly the extracellular fructosyltransferase production, where as histidine and leucine had little inductive effect on intracellular fructosyltransferase production. Enhanced production of fructosyltransferase by Penicillium purpurogenum was observed when sucrose content was restored by additional sucrose feeding to the cultivation medium during production period.
