Microplastic is a minute particle of chemical pollutant in marine environment and classified as less than 5 mm size. The microplastics could not degrade for long years and they are ingested, incorporated, and accumulated in tissues of living organisms, particularly can cause various ecotoxicological effects for their behavioural change, cytotoxicity, neuro-toxicity effects, liver stress, etc. This preliminary study was investigated the abundance and accumulation of microplastic in marine fish of Indian mackerel (Rastrelliger kanagurta) gut region. Further, we identified the microplastic through stereomicroscope in Indian mackerel fish size up to 0.02 mm. In FT-IR analysis were identified the chemical group which were represents as nylon. In GC–MS analysis were identified that hexa decanoic acid and methyl ester plastic compounds as well as identify and screened the microplastic degrading bacteria from fish gut through partial 16S rRNA gene sequencing analysis it was shows that the isolate reveals a Pseudomonas sp. As a result, it is possible that gut bacteria have a probiotic role in fish gut to may degrade microplastics.
