Larvicidal toxins from Bacillus thuringiensis subspp. kurstaki, morrisoni (strain tenebrionis), and israelensis have no microbicidal or microbiostatic activity against selected bacteria, fungi, and algae in vitro.
The insecticidal toxins from Bacillus thuringiensis subspp. kurstaki (antilepidopteran), morrisoni strain tenebrionis (anticoleopteran), and israelensis (antidipteran) did not affect the growth of a variety of bacteria (8 gram-negative, 5 gram-positive, and a cyanobacterium), fungi (2 Zygomycetes, 1 Ascomycete, 2 Deuteromycetes, and 2 yeasts), and algae (primarily green and diatoms) in pure and mixed culture, as determined by dilution, disk-diffusion, and sporulation assays with purified free and clay-bound toxins. The insecticidal crystal proteins from B. thuringiensis subspp. kurstaki and israelensis had no antibiotic effect on various gram-positive bacteria.
