Comparative analysis of microbial communities on apricot kernel shells and walnut shells influenced by post-harvest conditions
AI summary Read the abstract
Apricot kernel shells and walnut shells were evaluated as natural alternatives to synthetic microplastic exfoliants used in cosmetics, with their microbial communities characterized under different post-harvest storage conditions. Replacing petroleum-based plastic microbeads with agricultural byproducts in personal care products could significantly reduce the release of microplastics into waterways.

Agro-(Bio)Microplastics: Extraction, Identification, and Quantification Methodologies
AI summary Read the abstract
This paper examines methods for extracting, identifying, and quantifying microplastics from biodegradable bioplastics used in agriculture, which fragment into particles that are difficult to distinguish from conventional microplastics. Understanding whether bioplastics truly degrade safely is vital, as agricultural microplastic contamination of soil directly affects food crops consumed by humans.
Microplastic accumulation in agricultural soils – Impacts on crop microbiomes and soil health
AI summary Read the abstract
Researchers review how microplastics from mulch films, sewage sludge, and wastewater accumulate in agricultural soils, disrupting microbial communities, reducing enzyme activity essential for nutrient cycling, and accumulating in crop tissues, raising food safety concerns and highlighting the need for biodegradable alternatives and better wastewater treatment.
Identification of Microorganisms Related to Microplastics
AI summary Read the abstract
Plastic debris in aquatic environments is rapidly colonized by diverse microbial communities, with phototrophic organisms like cyanobacteria and diatoms attaching first before being succeeded by proteobacteria, forming what is known as the plastisphere. These microbial biofilms can alter plastic degradation rates and potentially harbor and transport pathogenic organisms, adding a biological dimension to microplastic pollution risks.
Identification of Microorganisms Related to Microplastics
AI summary Read the abstract
Plastic debris in aquatic environments attracts diverse microbial communities that differ from those in surrounding water, with these plastisphere microorganisms influencing both the degradation fate of plastics and the dispersal of potentially pathogenic or plastic-degrading microbes. Identifying which microorganisms colonize microplastics is essential for understanding both environmental risks and potential bioremediation opportunities.
