Tomato Growth Promotion Induced by Bacillus SPP

Biofertilizer containing plant growth promotingrhizobacteria offers great promise to promote agricultural sustainability. However, biofertilizer application is often restricted in the field application. To gain high-quality biofertilizer, seven bacteria producing spore, i.e., Bacilluslicheni form is F1-1, B.licheniformis F1-2, B. amyloliquefaciens ZH-3, B. altitudinis ZH-4, B. safensis ZH-5, B. licheniformis ZH-6, B.siamensis CM-2, were isolated from the rhizosphere soil. Two strains, i.e., F1-1, F1-2, showed cellulase activity. Strain CM-2 showed the production of IAA (79.58 mg L-1). All strains except CM-2 showed antimicrobial activity against plant pathogens (i.e., Rhizoctoniasolani, Fusarium oxysporum, Botrytis cinereapers). Inoculation with isolates resulted in differential growth responses of tomato. B.licheniformis F1-1 inoculation showed the highest increase in tomato fresh and dry weight over control plants, while B.siamensis CM-2 gained the maximum length of tomato. Hence, strains F1-1 and CM-2 have greater potential to be used for the production of biofertilizer to reduce chemical fertilizer.
