a, b Polyacrylamide gel electrophoretic pattern of total proteins of 12 Bt isolates (lanes from 1 to 12). Lane 1 M protein marker, lane 13 HD1. a Bt isolates were grown on LB broth at 28 °C shakers for 12 h to obtain vegetative growth. b Bt isolate strains were grown on T3 broth at 28 °C shaker for 5 days to allow spore formation
