Preliminary Study on Cellulaes Production from Trichaterma Konirgii zj4 Culfure

Abstract

Abstract: This paper comparedthe ability ofpr oducing cellulase of several fungi.Whenstrawpowder was used as primary carbon source,Trichoderma koningii zj4could produce relatively highcellulase.The mediummade of strawpowder as carbonsource and(NH 4 ) 2 SO 4 as nitrogensource withstraw powder/bran =2∶1was optimal for producing cellulase.The maximumce llulase activity reached at28℃and p H5.0when cultured144hours.The maximumcellalase activity of CMCan d filter paper was 453.2U /ml and 45U /ml respectively.

Key words: Trichoderma koningii zj4, cellulase, strawpowder, ferme ntation
