Removal of microplastic for a sustainable strategy by microbial biodegradation
Researchers reviewed which microorganisms — including Bacillus, Pseudomonas, and several fungi and algae species — show the greatest ability to break down microplastics, and highlighted how genetic engineering and combining multiple degradation methods could make biological plastic cleanup viable at larger scales.
Biodegradation of polyethylene (PE), polypropylene (PP), and polystyrene (PS) microplastics by floc-forming bacteria, Bacillus cereus strain SHBF2 isolated from a commercial aquafarm
Researchers found that a beneficial floc-forming bacterium, Bacillus cereus, isolated from a fish farm could break down polyethylene, polypropylene, and polystyrene microplastics when used as its sole carbon source. Over 60 days, the bacteria caused measurable weight loss and surface changes in the plastic particles, suggesting a potential biological approach to microplastic remediation in aquaculture settings.
Toxic Effects of Microplastics on Culture Scenedesmus quadricauda: Interactions between Microplastics and Algae
Researchers found that microplastics from multiple polymer types inhibit growth of the freshwater alga Scenedesmus quadricauda and induce oxidative stress, with toxicity varying by polymer type, particle size, and concentration.
Polystyrene microplastics interaction and influence on the growth kinetics and metabolism of tilapia gut probiotic Bacillus tropicus ACS1
Polystyrene microplastics were found to alter the gut microbiome of tilapia, disrupting the growth kinetics and metabolism of probiotic bacteria, with potential implications for fish health and aquaculture productivity.
Biological Responses of Bacillus subtilis toward Nanoplastics under Nutritional Stress in Freshwater Ecosystems
Researchers found that polystyrene nanoplastics are toxic to the bacterium Bacillus subtilis under nutrient-poor conditions typical of natural freshwater, with even very low concentrations (2 micrograms per liter) reducing bacterial growth during prolonged exposure. The bacteria initially defended themselves by secreting protective substances, but these defenses eventually failed, leading to irreversible cell death from membrane damage and oxidative stress.
Adaptive responses of Bacillus subtilis underlie differential nanoplastic toxicity with implications for root colonization
Researchers found that nanoplastic toxicity to the beneficial soil bacterium Bacillus subtilis varies significantly depending on the bacteria's growth mode. The study suggests that nanoplastics can substantially limit the ability of plant growth-promoting bacteria to colonize roots, with implications for soil health and agricultural productivity in environments contaminated with plastic particles.
Interplay of plastic pollution with algae and plants: hidden danger or a blessing?
Researchers tested the ability of three microalgae species to remove microplastics from water through bioadhesion, finding that all three species could adsorb particles onto their surfaces. Removal efficiency depended on particle size, surface charge, and algae cell morphology.
