Lysinibacillus acetophenoni and Pseudomonas stutzeri with High Salt effect, Recovered from High Salinity Soil Area (Indo-Gangetic Plain of India)

Soil salinity has affected many soil microbial communities as well as economic value of forest ecosystem for many years. The plant growth-promoting bacteria have developed several different mechanisms that have a positive influence on plant development and growth. Designated strain L-PB424 and P-PB466 was isolated and identified from saline soil of block Ashabutter khair forest in Punjab North zone in India, were investigated for their plant growth-promoting characters such as production of indole acetic acid, phosphate solubilization, Ammonium production and fermentation of polysaccharides. Comparative analysis of 16SrRNA gene sequences revealed that L-PB424 was closely related to Lysinibacillus manganicus DSM 26584 strain Mn1-7 (98.76%), on the other hand strain P-PB466 was closely related to Pseudomonas songnenensis strain NEAUST5-5. This research paper is a study in evaluation and variety of possible halophlic/halotolerant bacterial strains in salt-affected soils of block Ashabutter khair forest in Punjab North zone in India. The use of Halophilic bacteria in saline soil is interesting for future analysis and biotechnological development.
