Determined stability of the pectinases and cellulases over a broad pH range and two incubation time periods.
Mixed enzyme extract with buffer and incubated for 1 and 10 h at 37 °C.
Added the substrate to the buffered enzyme extract, and pectinase and cellulase activity was determined as described above.
Effect of activators and inhibitors on pectinase and cellulase activities
Performed to investigate the effect of several ions on enzyme activities,assays in the presence of different concentrations of Na+,K+,Ca2+, and Mg2+ chloride salts as well as sodium dodecyl sulfate (SDS).
Preincubated the enzyme sample with the compounds for 15 min.
