Summary

This systematic review catalogued microbial strategies for remediating carcinogenic polycyclic aromatic hydrocarbons (PAHs) from the environment, including enzymatic degradation, biofilm formation, and genetically engineered microorganisms. The research is relevant to microplastics because PAHs frequently adsorb onto microplastic surfaces, and microbial degradation of both the plastics and their associated pollutants is an active area of investigation.

Study Type Review

Abstract Degradation, detoxification or removal of the omnipresent polycyclic aromatic hydrocarbons (PAHs) from the ecosphere as well as their prevention from entering into food chain has never appeared simple. In this context, cost-effective, eco-friendly and sustainable solutions like microbes-mediated strategies have been adopted worldwide. With this connection, measures have been taken by multifarious modes of microbial remedial strategies, i.e., enzymatic degradation, biofilm and biosurfactant production, application of biochar immobilized microbes, lactic acid bacteria, rhizospheric-phyllospheric-endophytic microorganisms, genetically engineered microorganisms, and microbial fuel cell techniques etc. In this review, a nine-way directional approach which is based on the microbial resources reported over the last couple of decades has been described. Fungi found as the most dominant taxa among the CPAH-degrading microbial community constituting 52.2%, while bacteria, algae and yeasts occupied 37.4%, 9.1% and 1.3%, respectively. In addition to these, category-wise CPAH degrading efficiencies of each microbial taxa, consortium-based applications, CPAH-degradation related molecular tool, and factors affecting CPAH-degradation are the other important aspects of this review in light of their appropriate selection and application in the PAH-contaminated environment for better human-health management in order to achieve a sustainable ecosystem.

Close encounters on a micro scale: microplastic sorption of polycyclic aromatic hydrocarbons and their potential effects on associated biofilm communities

Researchers investigated the sorption of polycyclic aromatic hydrocarbons (PAHs) onto microplastics and the potential cascading effects on biofilm communities associated with those microplastics in aquatic environments. They found that evaluating microplastics in isolation underestimates their ecological impact, as co-transported PAHs can alter the composition and function of biofilm communities across different compartments of aquatic ecosystems.

Current innovative approaches in reducing polycyclic aromatic hydrocarbons (PAHs) in processed meat and meat products

This review examines how cancer-causing polycyclic aromatic hydrocarbons (PAHs) form in processed meats during cooking methods like grilling, smoking, and frying. While not directly about microplastics, PAHs are relevant because they are among the harmful chemicals that can attach to microplastic surfaces in the environment. The paper discusses various strategies to reduce PAH formation in food, which matters for overall exposure to carcinogens through the diet.
