title: Biosynthesis of cellulolytic enzymes in semi-continuous cultures.
abstract: The aim of the research was to check the possibility of the semicontinuous cultivation of two Fusarium sp. strains producing cellulolytic enzymes. The cultures were grown in 5 1 fermentor on the mineral medium with addition of 1% cellulose cotton. In these cultures lasting 9 to 16 days the total activity was about 13 mg of reducing sugar/ml culture filtrate/hour. The comparison of the results of semi-continuous and periodic cultures pointed to the productivity of cellulolytic enzymes which was 1.2 to 2 times higher during one hour in semi-continuous cultures.
