Separating fungi degradation of cellulose and study cellulolytic activity in part of microflora Zanjan soil

Cellulose is the most abundant biopolymer on biosphere and one of the most important constituent in plant cell wall. Biodegradation of cellulose in soil has an important role in Carbon flow and changing fixed Carbon to C02 .and in producing stable biological products and bioenergy .In this research fungus were isolated from soil of Zanjan and Abhar , due to great potential of soil mycoflora in degradation of cellulose. Then isolates were grown in selective media containing Avicel as Carbon source and their cellulolytic activity were measured by DNS method. Among 67 samples, Aspergillus niger is the the most prevalent fungus between isolates and it has the highest activity among the isolates of Zanjan and Abhar.
