This book describes about the isolation and screening of Lignocellulolytic microorganisms especially fungi and bacteria for pulp and paper industry. The main aim of this work is to address the following points- * Isolation of lignocellulolytic bacteria and fungi through degraded wood and soil samples collected from different locations of reserve forest of F. R. I., Dehradun. * Production of cellulase enzyme through fermentation process. * Screening of the enzymes produced by lignocellulolytic microorganisms. * Estimation of CMCase and FPase activity by using DNS reagent.
