Four different pectinolytic enzyme activity essays were employed to detect different pectinases of Bacillus clausii from an extracellular protein cocktail. The mixture was obtained by ethanol precipitation. Each of the essays produced a positive result, indicating the presence of pectate lyase (PGL), pectin lyase (PL), pectin methyl esterase (PME), and polygalacturonase (PG). Activities of these enzymes were then assessed at differing concentrations of NaCl, detergents (SDS and tweens), ion chelators, and organic solvents. Results, presented as histograms, were the indication of original findings, as most of them were new to the relevant literature.
