The threat of microplastics and microbial degradation potential; a current perspective

Area of Science:

• Environmental Science
• Marine Biology
• Microbiology

Background:

• Microplastics accumulate globally in marine environments, posing significant ecological and health risks.
• These pollutants transfer through food chains and can carry pathogenic organisms, with potential toxic effects in humans.
• Plastic pollution necessitates urgent and safe mitigation strategies.

Purpose of the Study:

• To review global microplastic accumulation in marine environments.
• To assess the threat of microplastics to human health.
• To evaluate the biodegradation potential of marine bacteria and fungi for mitigation.

Main Methods:

• Literature review of scientific studies on microplastic pollution.
• Analysis of research on microbial biodegradation of plastics.
• Focus on cultivated marine microorganisms and the potential of uncultivated microbes.

Main Results:

• Microplastics are a pervasive marine pollutant with cascading effects on food webs.
• Human exposure to microplastics can lead to various toxicological outcomes.
• Marine bacteria and fungi show versatile biodegradation capabilities for different plastic types.

Conclusions:

• Microbial biodegradation offers a promising avenue for mitigating marine microplastic pollution.
• Exploring uncultivated marine microbial communities could unlock novel biodegradation strategies.
• Harnessing microbial potential is key to developing effective future solutions for plastic pollution.
