Bacillus licheniformis (BL ) strains are used for industrial production of exoenzymes, antibiotics and secondary metabolites, and also serve as probiotics. Some strains sequester heavy metals, promoting plant growth or inducing plant systemic resistance against stresses. However, investigations on t...
