Microbial degradation of microplastics by enzymatic processes: a review

Microplastic sampling techniques in freshwaters and sediments: a review

“…However, sorption and filtration processes coupled with membrane bioreactors lead to higher microplastics removal compared to other methods (Hamidian et al 2021;Padervand et al 2020). Othman and coworkers reviewed microplastics degradation through enzymatic processes (Othman et al 2021). ZnO nanorod photocatalysts excited by visible light were used to degrade low density polyethylene film in water (Tofa et al 2019).…”

A review on microplastic pollution in the mangrove wetlands and microbial strategies for its remediation

“…The polymeric MPs are specifically digested by microbial enzymes into component monomeric units which serve as a carbon source for the degrading microorganisms (Ganesh et al 2020;Bollinger et al 2020;Liu et al 2021). The enzymatic mechanisms of microbial degradation of MP were reviewed in detail by Othman et al (2021). Briefly, the microbial enzymes act via surface modification (Vertommen et al 2005) or polymer degradation (Gómez-Méndez et al 2018).…”

“…The microbial remediation of MPs is highly encouraged as their deployment causes the least harm to the environment (Shah et al 2008;Brooks et al 2011). From early 2020, a few authors have reviewed microbial deterioration of MPs (Yuan et al 2020;Othman et al 2021) and the distribution and fate of MPs in mangrove habitats (Deng et al 2020). Recently, it has been reported that mangrove areas accumulate more MPs compared to the unvegetated areas of wetlands (Huang et al 2021).…”

“…;Othman et al 2021). Despite slow progress, recent studies have attempted in vitro investigation of plastic degrading potential of microbes isolated from the mangrove habitats.…”

Innovations in applications and prospects of bioplastics and biopolymers: a review

“…Additionally, most of the plastics waste ends up in landfills, soil, oceans and water bodies, thus creating hazards for plants, terrestrial and aquatic animals and humans. Pollution by plastics has resulted in the death of more than 1 million seabirds and 100,000 sea animals globally (Othman et al 2021 ). Conventional petrochemical-based plastics are non-biodegradable because of which they last in landfills and oceans for thousands of years, thus affecting soil quality, microbial activity, flora and fauna.…”
