“…B. licheniformis and B. cenocepacia were reported as efficient Ksolubilizers. The inoculation of these strains in tomato plants, increases its growth parameters like leaf area, both root and shoot length and K content as well (44). Ksolubilizer with PGP ability have been exploited as agricultural agents for cereal crops under suitable inoculants for low temperature season, crops grown in regions like alpine, sub-alpine, high altitude regions and low temperature areas and used in the mitigation of K-deficient soils .…”

Potassium (K) is the foremost macronutrients for growth of plant, soil health and fertility. The huge application of NPK chemical fertilizers negatively impacts the economy and is a threat to environmental sustainability. The rapid depletion of K mineral in soil is due to the application of agrochemicals agricultural fields for the production of crops in India. In present investigation, K-solubilizing microbes (KSM) were isolated and enumerated from cereal crops growing in Sirmour Himachal Pradesh. A total 125 bacteria were isolated and screened for K- solubilization on Aleksandrov agar plates and found that 31 bacterial strains exhibited K-solubilization. These 31 K-solubilizing strains of bacteria were additionally screened for other plant growth promoting (PGP) potential including solubilization of minerals, production of siderophores, ammonia, hydrogen cyanide and indole acetic acids. The performance of an efficient K-solubilizer was evaluated for plant growth promoting ability in pot assay under in vitro conditions. The strain EU-LWNA-25 positively influenced shoot length, fresh weight, carotenoids and total sugar content than the full dose, half dose and control. The strain enhancing physiological and growth parameters was identified by BLASTn analysis as Pseudomonas gessardii EU-LWNA-25. K-solubilizing plant growth promoting bacteria could be suitable bioinoculants for Rabi seasonal crops and overcomes the challenges of sustainable agriculture in K-deficient soil.

“…The role of beneficial soil and plant microbiomes in promotion of plant growth and in amelioration of stress has been well documented. Soil and plant microbiomes enhance the fitness of plants under abiotic and biotic stress by different mechanisms [19,20]. The microbial solubilization of K under the stress conditions is one of the mechanisms for increasing the availability of K for the plants.…”

“…Engaging engineered microbiome can impart a secured and a financially stable approach then other techniques. Genetic engineering (GE) and biotechnology, GEMs are anticipated by modifying microbiome with a more persuasive protein to overexpress the desired character [18]. Genetically modifies microbes including algae, bacteria, and fungi have been applied to degrade various contaminants such as hexane, octane, oil spills, camphor, naphthalene, toluene, xylene, halobenzoates, and trichloroethylene.…”

Bioremediation is well accepted technology for the removal of pollutants produced by the anthropogenic activities and rapid industrialization. Different innovative tools such as microbes could be employed for the bioremediation of toxicity in environment. The microbial based bioremediation is one of the most effective tools due to maximum output, cost-effectiveness, and non-toxic process. Microbes having capability to remediate, habors the different hot spots such as plant microbiomes (epiphytic, endophytic, and rhizospheric), and diverse extreme environments (psychrophilic, thermophilic, xerophilic, halophilic, acidophilic, and alkaliphilic). Microbes are known to degrade the different pollutants including azo dyes, heavy metals, agricultural wastes, pesticides, and polycyclic aromatic hydrocarbons. Thus, utilization of microbes and their consortia is highly accepted and recommended technology for decontamination of environment is a prime concern on account of being eco-friendly, non-hazardous, safe, and costeffective. In the past two decades, there have been recent advances in bioremediation techniques with the ultimate goal to restore polluted environment for better survival of living beings and protecting the sanctity of nature. In the present review, the current scenario of microbial bioremediation of different pollutants is discussed along with factors affecting the bioremediation.
