ClearPivotal Role of Microbes in Solid Waste Management
This review discusses the role of lactic acid bacteria in solid waste management, including their use as probiotics in food systems and their potential to produce polylactic acid (PLA), a biodegradable plastic. Using microbes to produce bioplastics that break down naturally could help reduce persistent microplastic pollution.
Microbial synthesis of eco-friendly polylactate plastic from low-cost agro-industrial wastes as an alternative to petrochemical-based plastic
This study isolated soil and food waste bacteria capable of producing polylactic acid (PLA) bioplastic from low-cost agricultural byproducts. PLA is a biodegradable alternative to petroleum-based plastics, and producing it from waste feedstocks improves both its economics and environmental profile.
Emerging technologies for conversion of sustainable macroalgal carrageenan biomass into L-lactic acid: A state-of-the-art review
This review examines how macroalgae (seaweed) can be converted into lactic acid for making polylactic acid (PLA), a biodegradable plastic alternative. Using non-food biomass like seaweed to produce biodegradable plastics could help reduce dependence on fossil-based plastics that generate persistent microplastic pollution.
Application of an oxidative-biological treatment strategy for production of lactic acid and biomass from vinasse of sugarcane bioethanol industry
Researchers evaluated lactic acid and biomass production from vinasse, a sugarcane bioethanol byproduct, by cultivating Lactococcus lactis strains on ozone- and air-pretreated vinasse at concentrations of 0-33% v/v. The study found that oxidative pretreatment reduced inhibitory compounds, enabling viable microbial growth and lactic acid yields from this high-strength organic waste stream.

Despite its title referencing lactide synthesis, this paper studies a one-step chemical process for producing lactide (a precursor to biodegradable PLA plastic) using an acid catalyst — not microplastic pollution. It examines reaction chemistry and yield optimization, and is not relevant to microplastics or human health.

Researchers investigated the modification of poly(lactic acid) through plasticization to improve its mechanical properties for use in packaging industry applications as a biodegradable alternative to conventional plastics.
Enhancing volatile fatty acid production from sewage sludge in batch fermentation tests
This paper is not directly about microplastics; it compares four pre-treatment methods for sewage sludge to optimize the production of volatile fatty acids through acidogenic fermentation, finding potassium permanganate treatment most effective — relevant to wastewater resource recovery.
Plastic waste as a novel substrate for industrial biotechnology
This paper reviewed the potential of plastic waste as a novel substrate for industrial biotechnology, arguing that plastic polymers could serve as feedstocks for microbial processes that generate value-added chemicals or fuels.
Leachate as an alternative culture medium for microalgae growth: Perspectives and challenges
Not relevant to microplastics — this review focuses on growing microalgae in landfill leachate as a way to produce biofuels and treat wastewater, with only incidental mention of contaminants in that leachate.
Selection of polyhydroxybutyrate-producing bacteria and their polyhydroxybutyrate production using cassava and glycerol as carbon sources
Researchers selected effective polyhydroxybutyrate (PHB)-producing bacteria and evaluated their ability to produce PHB using low-cost carbon sources including cassava and glycerol, aiming to reduce the high production costs that limit PHB bioplastics as a competitive alternative to synthetic plastics.
