Abstract

Bacillus amyloliquefaciens is one of the many Bacillus species which is used as a probiotic, exerting health benefits to the host. B. amyloliquefaciens is a gram-positive, rod shaped bacteria with peritrichous flagella. The species also produces enzymes viz. cellulases, amylases, and proteases, which aid in digestion. The species is principally utilized as a feed additive substance for domestic animals and birds. It is gaining importance as plant growth promoter rhizobacteria (PGPR). Various strains of B. amyloliquefaciens are used as a biocontrol agent against Peach gummosis, Fusarium oxysporum growth, algal blooms, and anthracnose rot caused by Colletotrichumacutatum. Recently, it is being used to induce defense mechanism in plants against various plant pathogens. B. amyloliquefaciens is capable of producing a broad-spectrum antifungal protein, Baciamin, along with a lipopeptide compound known as Bacillomycin D, which also shows an antifungal property. The contribution of B. amyloliquefaciens in Gene expression regulation in rice and inducing tolerance against various abiotic stresses is crucial in agricultural field.
