“…Postpyrolysis modifications of biochar benefit microbial inoculants through chemical and physical modifications or supplementation with minerals . When using biochar as a carrier for PGPB, consideration should also be given to the properties of the soil to which the biochar-based bacterial inoculant will be applied, as well as the properties of the bacterial surface and plant growth conditions. , Therefore, characterizations of the soil, plants, PGPB, and biochar are important steps for specific agricultural and environmental applications .…”

“…This may open up opportunities for the use of biochars (in remediation) that fail to meet the standards required for use in uncontaminated soils. In addition, before using biochar to immobilize microbial inoculants, it is very important to perform toxicity, growth, and metabolism tests to determine what type of and at what rate biochar is compatible with particular microorganisms . In some cases, biochar may contain contaminants such as heavy metals, most of which are introduced from biomass feedstock sources (e.g., plants can absorb heavy metals from the soil).…”

The contamination of soil with organic pollutants has been accelerated by agricultural and industrial development and poses a major threat to global ecosystems and human health. Various chemical and physical techniques have been developed to remediate soils contaminated with organic pollutants, but challenges related to cost, efficacy, and toxic byproducts often limit their sustainability. Fortunately, phytoremediation, achieved through the use of plants and associated microbiomes, has shown great promise for tackling environmental pollution; this technology has been tested both in the laboratory and in the field. Plant–microbe interactions further promote the efficacy of phytoremediation, with plant growth-promoting bacteria (PGPB) often used to assist the remediation of organic pollutants. However, the efficiency of microbe-assisted phytoremediation can be impeded by (i) high concentrations of secondary toxins, (ii) the absence of a suitable sink for these toxins, (iii) nutrient limitations, (iv) the lack of continued release of microbial inocula, and (v) the lack of shelter or porous habitats for planktonic organisms. In this regard, biochar affords unparalleled positive attributes that make it a suitable bacterial carrier and soil health enhancer. We propose that several barriers can be overcome by integrating plants, PGPB, and biochar for the remediation of organic pollutants in soil. Here, we explore the mechanisms by which biochar and PGPB can assist plants in the remediation of organic pollutants in soils, and thereby improve soil health. We analyze the cost-effectiveness, feasibility, life cycle, and practicality of this integration for sustainable restoration and management of soil.

“…An appropriate selection of the source of the biomass and pyrolysis temperature together determine the distinct physico-chemical properties of the biochar. 3 The major physico-chemical properties, such as a high specific surface area, 4 high porosity, 5 thermal stability, 6 high amount of surface activity, 7 and functionality, 8 corrosion resistance, 9 biocompatibility, 10 and electric conductivity, 11–14 are important for the performance and efficiency of biochar in various applications. Recently, numerous strategic methodologies, including optimisation of pyrolysis conditions and temperature, activating agents, and pH, have been developed to tailor the physico-chemical properties of biochar.…”
