Unlabelled: Chlorpyrifos (CP) is a persistent organophosphorus pesticide (OP) used in soil ecosystem for insect control. Bioremediation process has been proven promising in degrading these toxic molecules and restoring the physio-chemical properties of soil. This work reports a laboratory microcosm study in both non-sterile & sterile conditions, conducted over a period of 56 days to examine the combined effect of additional supplements like biostimulants (BSs) such as N, P, and K in the presence of suitable carrier materials (compost, wheat straw, and corncob) along with bioaugmentation by a sp. CPD-03 on CP degradation from the contaminated soil. CP degradation was thoroughly monitored at an interval of 7 days over a period of 56 days. Results showed biostimulation and bioaugmentation along with compost as carrier material had shown higher CP degradation efficiency of 76 ± 2.8 and 74 ± 1.6% in non-sterile and sterile microcosms over a period of 56 days. Moreover, bacterial community profiling (16s rRNA and gene) demonstrated increased microbial counts, corroborating the efficiency of the bioremediation process. The survival of CPD-03 at the end of the assay validated its ability of colonizing modified soils. By this integrated method with compost as carrier material, bioremediation process could be enhanced for restoration CP-contaminated soils.

Genomic reorganisation between species and horizontal gene transfer have been considered the most important mechanism of biological adaptation under selective pressure. Still, the impact of mobile genes in microbial ecology is far from being completely understood. Here we present the collection and characterisation of microbial consortia enriched from environments contaminated with emerging pollutants, such as non-steroidal anti-inflammatory drugs.

Crude oil pollution of soil is an important issue that has serious effects on both the environment and human health. Phytoremediation is a promising approach to cleaning up oil-contaminated soil. In order to facilitate phytoremediation effects for oil-contaminated soil, this study set up a pot experiment to explore the co-application potentiality of L.

Phenolic compounds are an extensive group of natural and anthropogenic organic substances of the aromatic series containing one or more hydroxyl groups. The main sources of phenols entering the environment are waste from metallurgy and coke plants, enterprises of the leather, furniture, and pulp and paper industries, as well as wastewater from the production of phenol-formaldehyde resins, adhesives, plastics, and pesticides. Among this group of compounds, phenol is the most common environmental pollutant.

Slow decomposition rates of cereal crop residues can lead to agronomic challenges, such as nutrient immobilization, delayed soil warming, and increased pest pressures. In this regard, microbial inoculation with efficient strains offers a viable and eco-friendly solution to accelerating the decomposition process of crop residues. However, this solution often focuses mostly on selecting microorganisms based on the appropriate enzymic capabilities and neglects the metabolic versatility required to utilize both structural and non-structural components of residues.

Although bioremediation is considered the most environmentally friendly and sustainable technique for remediating contaminated soil and water, it is most effective when combined with physicochemical methods, which allow for the preliminary removal of large quantities of pollutants. This allows microorganisms to efficiently eliminate the remaining contaminants. In addition to requiring the necessary genes and degradation pathways for specific substrates, as well as tolerance to adverse environmental conditions, microorganisms may perform below expectations.
