Title
Characteristics of enzymes from Acremonium cellulolyticus strains and their utilization in the saccharification of potato pulp
Abstract

•We identified the abilities of 4 Acremonium cellulolyticus strains to produce various enzymes.•We performed saccharification of potato pulp with the crude enzymes from the 4 strains.•A. cellulolyticus CF-2612 provided the highest saccharification of potato pulp.

In this study, the abilities to produce enzymes by four Acremonium cellulolyticus strains were analyzed. Saccharification of potato pulp was performed to investigate the effects of the enzymes produced by A. cellulolyticus and to confirm the possibility of using A. cellulolyticus in the saccharification of potato pulp. Amylase, pectinase, galactosidase, and cellulase were produced by A. cellulolyticus from several carbon sources. Potato pulp was found to be a suitable substrate for A. cellulolyticus growth. The addition of cellulose not only improved the activity of cellulase but also improved the activity of α-galactosidase. Lactose and galactose induced the production of β-galactosidase and pectinase. Four strains of A. cellulolyticus were cultured in potato pulp to evaluate their abilities to produce cellulase, amylase, pectinase and galactosidase. Among them, A. cellulolyticus strain CF-2612 exhibited the highest production of all the enzymes. By using the crude enzymes from A. cellulolyticus strain CF-2612, 86% yield for glucose and 94% yield for galactose were achieved after 80 h of saccharification of potato pulp.
