Utilization of banana agricultural waste: production of cellulases by soil fungi.

Abstract

Banana a major cash crop of Maharashtra is cultivated over 46900 hectares generating large amount of agro waste after the harvest. Attempts were made to utilize these agro wastes for production of cellulases. Of the 127 fungi isolated from the soil of banana field, 12 fungi were found to utilize cellulose as source of carbon. Trichoderma lignorum showed appreciable cellulolytic activity. It produced Cl, Cx and beta glucosidase in Carboxymethyl Cellulose Peptone medium as well as on agro waste based medium containing leaves, stem and rhizome powders. T. lignorum (0. 45 U/ml) produced maximum enzymes on leaf based medium.
