Cellulase mobility in decomposing leaf litter

The relative mobility of Trichoderma viride cellulase components adsorbed to several types of leaf litter was determined by measuring the redistribution of enzyme activity after 18 h in a recirculating column. The mobility of native cellulase associated with decomposing leaf litter was also measured...

Description
Summary:The relative mobility of Trichoderma viride cellulase components adsorbed to several types of leaf litter was determined by measuring the redistribution of enzyme activity after 18 h in a recirculating column. The mobility of native cellulase associated with decomposing leaf litter was also measured. Despite differences in adsorptive capacities among litters, there no species-specific differences in the relative mobilities of adsorbed cellulase components. There were differences among enzymes. Exoglucanase and endoglucanase had similar but higher mobilities than beta -glucosidase. Native cellulase mobility was low for deciduous litter, but white pine litter showed an enzyme-specific pattern with beta -glucosidase the least mobile and endoglucanase the most.
