Abstract

In current studies enzymes production and antibiotics sensitivity of some strains of Xanthomonas oryzae pv. oryzae tested in in-vitro conditions. Results of biochemical tests like catalase, amylase (starch hydrolysis) and growth on Yeast Dextrose Calcium Carbonate Agar (YDCA) varied among the isolates. The results regarding catalytic and amylase activity showed that out of 19 isolates, 18 isolates (95%) were Catalase positive and 1 isolate (5%) Catalase negative. 16 strains (84%) were amylase positive and 4 strains (21%) were amylase negative. SHB-5, SHB-12, SHB-116 showed maximum inhibition zone against streptomycin where as SHB-18, SHB-19 showed minimum inhibition
