Abstract/Description: | The intensive use of chemical fertilizers, monoculture and irrigation with surface saline water has resulted in the deterioration of soil health by enhancing the level of salinity in the Eastern Indo-Gangetic Plains of India. Therefore, diversity of halotolerant bacteria adapted to that environment and possessed the ability to produce plant growth hormones was explored, that could be used for salt stress amelioration. The 16S rRNA gene sequencing and fatty acid methyl ester (FAME) were used for diversity analysis of salt-tolerant bacilli. Among the 95 isolates, 55 strains showed plant growth promotion traits, production of industrially important enzymes (amylase, protease and cellulase) and tolerance to more than 4% NaCl. Using partial 16S rRNA sequences and FAME comparisons, 21 different species of Bacillus and Bacillus-derived genera were identified, viz. Bacillus megaterium, B. subtilis, B. licheniformis, B. firmus, B. horikoshii, B. pumilus, Bacillus sp., B. safensis, B. thuringiensis, B. simplex, B. agri, B. flexus, B. oceanisediminis, B. cereus, B. arsenicus, Paenibacillus dendritiformis, Lysinibacillus sp., L. sphaericus, B. marisflavi, Terribacillus sp., and B. mycoides. These isolates possess the ability to tolerate high salt, form endospores, withstand harsh environments, and also have the potential for plant growth promotion, which could be useful in formulation of new inoculants to enhance the availability of nutrients for crop growth under saline conditions. |
