Cellulose Degradation by Cellulose-Clearing and Non-Cellulose-Clearing Brown-Rot Fungi

Cellulose degradation by cellulose-clearing and non-cellulose-clearing brown-rot fungi.

Cellulose degradation by four cellulose-clearing brown-rot fungi in the Coniophoraceae-Coniophora prasinoides, C. puteana, Leucogyrophana arizonica, and L. olivascens-is compared with that of a non-cellulose-clearing brown-rot fungus, Poria placenta. The cellulose- and the non-cellulose-clearing brown-rot fungi apparently employ similar mechanisms to depolymerize cellulose; most likely a nonenz...

Changes in Molecular Size Distribution of Cellulose during Attack by White Rot and Brown Rot Fungi.

The kinetics of cotton cellulose depolymerization by the brown rot fungus Postia placenta and the white rot fungus Phanerochaete chrysosporium were investigated with solid-state cultures. The degree of polymerization (DP; the average number of glucosyl residues per cellulose molecule) of cellulose removed from soil-block cultures during degradation by P. placenta was first determined viscosimet...

Cellulose degradation by oxidative enzymes

Enzymatic degradation of plant biomass has attracted intensive research interest for the production of economically viable biofuels. Here we present an overview of the recent findings on biocatalysts implicated in the oxidative cleavage of cellulose, including polysaccharide monooxygenases (PMOs or LPMOs which stands for lytic PMOs), cellobiose dehydrogenases (CDHs) and members of carbohydrate-...

The Decomposition of Cellulose by Soil Fungi*

Enhancement of Cellulose Degradation by Cattle Saliva

Saccharification of cellulose is a promising technique for producing alternative source of energy. However, the efficiency of conversion of cellulose into soluble sugar using any currently available methodology is too low for industrial application. Many additives, such as surfactants, have been shown to enhance the efficiency of cellulose-to-sugar conversion. In this study, we have examined fi...
