    Joe et al. (2016) stated the phosphate-solubilizing bacterial role in plant growth promotion by isolating Bacillus sp. and Acinetobacter sp. from Phyllanthus amarus. Such bacteria have salt-tolerant and phosphate-solubilizing properties and are also able to decrease fertilizer consumption. Moreover, it is reported that the inoculation of bacterial strains increased the
