“…In previous studies of DEHP biodegradation, considerable progress has been made in the bioremediation of DEHP-contaminated environments. Compared with other methods, bioremediation can irreversibly depolymerize the composition the pollutants [ 72 , 73 ]. However, the available DEHP-degrading strains are limited.…”

Di-(2-ethylehxyl) phthalate (DEHP) is one of the most broadly representative phthalic acid esters (PAEs) used as a plasticizer in polyvinyl chloride (PVC) production, and is considered to be an endocrine-disrupting chemical. DEHP and its monoester metabolites are responsible for adverse effects on human health. An efficient DEHP-degrading bacterial strain Rhodococcus ruber YC-YT1, with super salt tolerance (0–12% NaCl), is the first DEHP-degrader isolated from marine plastic debris found in coastal saline seawater. Strain YC-YT1 completely degraded 100 mg/L DEHP within three days (pH 7.0, 30 °C). According to high-performance liquid chromatography–mass spectrometry (HPLC-MS) analysis, DEHP was transformed by strain YC-YT1 into phthalate (PA) via mono (2-ethylehxyl) phthalate (MEHP), then PA was used for cell growth. Furthermore, YC-YT1 metabolized initial concentrations of DEHP ranging from 0.5 to 1000 mg/L. Especially, YC-YT1 degraded up to 60% of the 0.5 mg/L initial DEHP concentration. Moreover, compared with previous reports, strain YC-YT1 had the largest substrate spectrum, degrading up to 13 kinds of PAEs as well as diphenyl, p-nitrophenol, PA, benzoic acid, phenol, protocatechuic acid, salicylic acid, catechol, and 1,2,3,3-tetrachlorobenzene. The excellent environmental adaptability of strain YC-YT1 contributed to its ability to adjust its cell surface hydrophobicity (CSH) so that 79.7–95.9% of DEHP-contaminated agricultural soil, river water, coastal sediment, and coastal seawater were remedied. These results demonstrate that R. ruber YC-YT1 has vast potential to bioremediate various DEHP-contaminated environments, especially in saline environments.

“…The pollution cause because of deposition and use of plastic debris is a serious threat to the environment. As reported high-salinity wastewater containing around 5000-6000 mg/L NaCl is produced by the domestic and industrial effluent 13,16,17 . The bioremediation of such pollutant and it's as compared to any other methods is more efficient as the degradation by this mean can irreversibly depolymerize these compounds.…”

“…A previous study suggested that the effects of BC on degradation of pollutants in soil showed mixed results (He et al, 2018): accelerating or reducing the degradation rate. There are several reasons for reducing the natural degradation rate by BC.…”

“…Biochar (BC) could improve the soil quality and enhance the adsorption and degradation of pollutants to reduce the microbial toxicity of the pollutants, so it is commonly used for the improvement of organic contaminated soil, although the effects of BC on degradation of organic pollutants showed mixed results currently (He et al, 2018). Some studies showed that BC could accelerate the degradation rate of organic pollutants as a result of enhancing the microbial activity or the microbial utilization of the organic pollutants on the BC.…”

Microplastics (MPs) have been attracting wide attention. Biochar (BC) application could improve the soil quality in the contaminated soil. Currently, most studies focused on the effect of MPs or BC on the soil properties and microbial community, while they neglected the combined effects. This study investigated the combined effects of BC or ball-milled BC (BM) and polyethylene plastic fragments (PEPFs) and degradable plastic fragments (DPFs) on the removal of polycyclic aromatic hydrocarbons (PAHs) and phthalate esters (PAEs) from the PAH-contaminated soil and the potential microbial ecological mechanisms. The results showed that BC or BM combined with PEPF could accelerate the removal of PAHs and PAEs. PEPF combined with BM had the most significant effect on the removal of PAHs. Our results indicating two potential possible reasons contribute to increasing the removal of organic pollutants: (1) the high sorption rate on the PEPF and BC and (2) the increased PAH-degrader or PAE-degrader abundance for the removal of organic pollutants.
