Certain rhizobacteria referred to as ‘plant growth-promoting rhizobacteria’ (PGPR) can contribute towards improved plant growth and stress tolerance and are currently of great interest for sustainable agriculture. A successful PGPR is capable of establishing itself in the rhizosphere of inoculated plants. Root colonization is an essential step in the interaction amongst plant-associated bacteria and host plant and is a multifaceted phenomenon governed by various biotic and abiotic factors. In the present investigation, an isolate MT7 obtained from maize rhizosphere and identified as Bacillus sp. was tested for its ability to perform in the tomato rhizosphere. It was screened for its survival under various abiotic stresses like salt, drought, heavy metals, and temperature and found to tolerate 10% salt stress, drought stress up to -0.73 MPa (25% PEG), heavy metals like Cr, Cu, and Ni above ...

The perilous effects of nitrate present in the environment pose a major threat to human and animal health. Bioremediation provides a cost‐effective and environmental friendly method to deal with this problem. The process of aerobic denitrification can reduce nitrate compounds to harmless dinitrogen gas. This review provides a brief view of the exhaustive role played by aerobic denitrifiers for tackling nitrate pollution under different ecological niches and their dependency on various environmental parameters. It also provides an understanding of the enzymes involved in aerobic denitrification. The role of aerobic denitrification to solve the issues faced by the conventional method (aerobic nitrification–anaerobic denitrification) in treating nitrogen‐polluted wastewaters is elaborated.
