Figure 5. Quantitative assessment of the enzymatic activities of extracellular fractions against chromomeric substrates and rice straw.

All bacterial strains that were found to be cellulase positive by the agar plate assay were grown in liquid medium, and their extracellular fractions were tested for the hydrolysis of various substrates. Each graph indicates the substrate. Black bars represent strains that exhibited significantly higher activities compared to the negative controls, while white bars represent negative strains. The data represent the average and standard deviation of two different assays.
