Fig. 3From: Efficacy of the vegetative cells of Lysinibacillus sphaericus for biological control of insecticide-resistant Aedes aegypti In vitro evidence of the hemolytic and chitinase activity of L. sphaericus strains. a Formation of halo on SBA at 48 h indicate hemolysis. b Halo around the growth areas indicate degradation of chitin on MSM supplemented with colloidal chitin. The numbers in the figure indicate L. sphaericus strains: 1, III(3)7; 2, 2362; 3, OT4b.25Back to article page
