“…CCI has been employed in numerous studies to date [29][30][31][32][33][34]. Considering the scale given, the ten beaches were classi ed from "clean" to "extremely dirty" depending on the quantity of plastic litter on In this study, the identi cation of distinct sources for each litter item collected was conducted following the approach described by [81].…”

Background: Fishing activity is a major source of marine litter on beaches, but most studies focus on recreational beaches. In this study, we assessed the abundance, composition, source and spatial distribution of marine litter on ten fishing beaches along Palk Bay, on the southeast coast of India. We also used social media to collect data on the impact of fishing litter on marine animals in the study area. Results: A total of 4,227 marine litter and their average density of 0.70 items/m2 were collected. Plastic (84.54%) is the most abundant in the study area, followed by cloths (7.46%), glass (5.19%), and rubber (3.47%). From the result, the value of CCI ranges from 6.26 to 25.7 indicating that the coast is "moderately clean" to "extremely dirty". The majority of the marine litter collected originated from fishing activity. The most common are string and cord, fishing lines, fishing gear, floats and buoys. Conclusion: The presence of this type of marine litter can produce serious environmental issues, such as ghost fishing, that impacts a large variety of marine species. A total of 25 of the olive ridley turtles (Lepidochelys olivacea) were entangled in fishing litter between 2018 and 2020. Most of the reported entanglements were due to discarded or lost fishing gear, which shows the importance of managing this type of litter in India. It is important to manage the litter related to the fishing activity by educating fishermen and organizing clean-up campaigns.

“…Dey et al (2020) reported a 20-fold increase in the carbonyl index by investigating the catabolic repertoire of natural bacteria for plastic biodegradation in one of their studies [77]. Akarsu et al (2022) also reported higher carbonyl indexes ranging from 0.23 to 0.53 [63]. Normally this means that ST3 and ST6 strains have better capability to degrade polyethylene compared to the microorganisms in their study.…”

“…Similarly, Sowmya et al (2015) reported the occurrence of holes, scions, and cracks on the surface of the PE with fungal consortia [80]. Moreover, some researchers also investigated the bacteria surface interactions [63,81]. According to this, the secretion of extracellular enzymes by the isolates results in the formation of a biofilm on the cell surface.…”

“…SEM (Gemini Zeiss Supra 55, Oberkochen, Germany) was used to view the morphology of the degraded PE MPs'. In addition, the carbonyl index was used to evaluate the oxidation states of MPs and the deterioration in their mechanical properties in this study [63]. The carbonyl index has a fixed location and is free from other bands that may interfere since it has been used for many years to monitor changes in the carbonyl band (C = O) [64].…”

Microplastics (MPs) pose potential public health challenges because of their widespread occurrences in all environmental compartments. While most studies have focused on the occurrence fate of microplastics in wastewater treatment systems, the biodegradation of microplastics in wastewater is generally little understood. Therefore, we used two Gram-positive and thermophilic bacteria, called strain ST3 and ST6, which were identified by morphological, biochemical, physiological, and molecular analyses, to assess the growth and biodegradation potential of two different sized (50 and 150 m) polyethylene particles. The degradation was monitored based on structural and surface morphological changes. According to 16S rRNA analyses, ST3 and ST6 were identified as Anoxybacillus flavithermus ST3 and Anoxybacillus sp. ST6, respectively. The occurrence of cracks, holes, and dimensional changes was detected by scanning electron microscopy. Moreover, critical characteristic absorption band formation and modifications were determined by Fourier transform infrared spectroscopy. In addition to these, it was found that Anoxybacillus flavithermus ST3 and Anoxybacillus sp. ST6 produced high level of alpha-Amylase. These results showed that thermophilic bacteria are capable of the biodegradation of microplastics and production of alpha-Amylase.
