Histomorphological Changes in Fish Gut in Response to Prebiotics and Probiotics Treatment to Improve Their Health Status: A Review
This review summarizes how prebiotics and probiotics, beneficial supplements added to fish feed, can improve gut health and disease resistance in farmed fish. A healthy gut microbiome is critical for nutrient absorption and immune defense in fish. While not directly about microplastics, the research is relevant because microplastics are known to disrupt gut bacteria in aquatic organisms, and probiotics may help counteract some of those effects.
Bacillus subtilis, a promising bacterial candidate for trapping nanoplastics during water treatment
Researchers found that the probiotic bacterium Bacillus subtilis can effectively trap polystyrene nanoplastics from water, with most nanoparticles clustering around the bacterial cells. At a concentration of 10 mg/L, over 73% of the nanoplastics' environmental state was altered through interaction with the bacteria. The study suggests B. subtilis could be a promising candidate for biological nanoplastic removal during water treatment, while simultaneously processing nitrogen compounds.
Unraveling Microplastic-Biofilm Nexus in Aquaculture: Diversity and Functionality of Microbial Communities and Their Effect on Plastic Traits
Researchers incubated five common types of microplastics in an aquaculture pond for 128 days and found that biofilm formation varied significantly depending on the plastic type, with polypropylene and polyethylene supporting the richest microbial communities. PET microplastics attracted more plastic-degrading bacteria like Pseudomonas, while all plastic types enriched potentially pathogenic microorganisms. The findings highlight how different microplastics selectively shape microbial colonization in aquaculture environments, with implications for both environmental health and food safety.
Study on the dynamics of microplastics in the biofloc system for Nile tilapia (Oreochromis niloticus) aquaculture
Researchers studied how microplastics behave in biofloc aquaculture systems — where beneficial bacteria clusters are used to improve water quality — finding that microplastics accumulate in both the bacterial clusters and tilapia tissues, with intestinal contamination rising sharply at higher plastic concentrations. The results show that biofloc technology does not protect fish from microplastic exposure and that plastic management is essential for safe aquaculture.
Correlation of Water Quality with Microplastic Exposure Prevalence in Tilapia (Oreochromis niloticus)
Researchers exposed tilapia to polyethylene microplastics at three concentrations and assessed effects on water quality and microplastic accumulation in gastrointestinal, liver, gill, and gonad tissues, finding that higher concentrations were associated with elevated microplastic prevalence and tissue-specific accumulation patterns.
