Abstract
Xanthomonas campestris pv. viticola is the causal agent of bacterial leaf spot disease of grapes. This study describes the screening and assay of extracellular enzymes produced by the pathogen namely amylase, cellulase, protease lipase and ï¢-1, 3 glucanase. The enzyme producing capacity of Xanthomonas campestris pv. viticola was assessed along with five other Xanthomons sp. All the Xanthomons sp. were found to produce protease, amylase, cellulase and lipase but their quantity varied. Xcv had shown highest protease, lipase and amylase activity whereas lowest cellulase activity with respect to other Xanthomons sp. ï¢ -1, 3 glucanase activity was significantly similar in all Xanthomons sp.
