“…They can alter water properties, affecting algal growth, species composition, and nutrient dynamics in lakes. Microplastics also interact with fungi, with some capable of degrading them [98]. These impacts on microorganisms, bacteria, fungi, and algae can have cascading effects on lake ecosystems [99].…”

The paper discusses a literature survey of the Impact of Sewage Treatment Plant (STP) effluents on surface water bodies in the special context of lakes and ponds. The sewage effluent even after conventional treatment has residual pollutants such as Organic Matter, Heavy Metals, Nutrients, and Emerging Contaminants such as Nanomaterial, PPCPs, EDCs, Microplastics, etc., which can have various negative impacts on aquatic ecosystems and human health. These pollutants can cause Eutrophication, Oxygen depletion, and toxicity in waterbodies posing a significant threat to the delicate balance of aquatic ecosystems. Further, they can harm biodiversity, induce population and behavioral shifts, cause Endocrine disruption, disrupt the food chain, and elevate the risk of antibiotic resistance, hence affecting aquatic Flora, Fauna, Wildlife, Birds, plankton, microbial communities, and Humans. The study aims to provide insights into strategies to mitigate the environmental impacts of STP effluents. Upgrading treatment technologies such as implementing nutrient removal strategies, utilizing land applications, implementing monitoring programs, and engaging stakeholders are some of the effective strategies for mitigating the impacts of STP effluent.

“…Similar studies reported Pseudomonas putida degrading HDPE by 12.07% (Hooda et al, 2023), Rhodococcus sp. degrading PP by 7.3% (Habib et al, 2020), Bacillus paramycoides degrading PS by 11.12% (Pikoli et al, 2022), Lysinibacillus sp degrading PE by 9% (Jeon et al, 2021), and Alcaligene faecalis degrading PA-6 by 27% (Oulidi et al, 2022). Hossain et al, (2023) reported that these plastics degrading bacteria have floc-forming ability.…”

The ubiquitous proximity of the commonly used microplastic (MP) particles particularly polyethylene (PE), polypropylene (PP), and polystyrene (PS) poses a serious threat to the environment, and human health globally. Biological treatment as an environment-friendly approach to MPs pollution has recent interest when the bio-agent has beneficial functions in their ecosystem. This study aimed to utilize beneficial floc-forming bacteria B. cereus SHBF2 isolated from an aquaculture farm in reducing the MPs particles (PE, PP, and PS) from their environment. The bacteria were inoculated for 60 days in a media containing MPs particles as a sole carbon source. On different days of incubation (DOI), the bacterial growth analysis was monitored and the MPs particles were harvested to examine their weight loss, surface changes, and alterations in chemical properties. After 60 DOI, the highest weight loss was recorded for PE, 6.87 ± 0.92%, which was further evaluated to daily reduction rate (k), 0.00118 gday− 1, and half-life (t1/2), 605.08 ± 138.52 days. The OD value (1.38 ± 0.18 Abs.) indicated the higher efficiency of bacteria for PE utilization, whereas the colony-forming unit showed the bacteria was growing at a higher rate while utilizing PP (1.04 × 1011 CFU/mL). Biofilm formation, erosions, cracks, and fragments were evident when the surface changes were observed using scanning electron microscopy (SEM) which resulted in the formation of carbonyl and alcohol group due to the oxidation and hydrolysis were confirmed using Fourier transform infrared spectroscopic (FTIR) analysis. The results confirmed and indicated a higher degree of biodegradation in all of the selected MPs types. Thus, this study revealed that the floc-forming bacteria, B. cereus SHBF2 has a high potential to be used as an effective MPs degrading bacteria.

The ubiquitous proximity of the commonly used microplastic (MP) particles particularly polyethylene (PE), polypropylene (PP), and polystyrene (PS) poses a serious threat to the environment, and human health globally.Biological treatment as an environment-friendly approach to counter MPs pollution has recent interest when the bioagent has beneficial functions in their ecosystem. This study aimed to utilize beneficial floc-forming bacteria B. cereus SHBF2 isolated from an aquaculture farm in reducing the MPs particles (PE, PP, and PS) from their environment. The bacteria were inoculated for 60 days in a media containing MPs particles as a sole carbon source. On different days of incubation (DOI), the bacterial growth analysis was monitored and the MPs particles were harvested to examine their weight loss, surface changes, and alterations in chemical properties. After 60 DOI, the highest weight loss was recorded for PE, 6.87 ± 0.92%, which was further evaluated to daily reduction rate (k), 0.00118 gday -1 , and half-life (t 1/2 ), 605.08 ± 138.52 days. The OD value (1.74 ± 0.008 Abs.) indicated the higher efficiency of bacteria for PP utilization, and so for the colony formation per define volume (1.04 × 10 11 CFU/mL). Biofilm formation, erosions, cracks, and fragments were evident during the observation of the tested MPs using the scanning electron microscope (SEM). The formation of carbonyl and alcohol group due to the oxidation and hydrolysis by SHBF2 strain were confirmed using the Fourier transform infrared spectroscopic (FTIR) analysis. Additionally, the alterations of pH and CO 2 evolution from each of the MPs type ensures the bacterial activity and mineralization of the MPs particles. The findings of this study have confirmed and indicated a higher degree of biodegradation for all of the selected MPs particles. B. cereus SHBF2, the floc-forming bacteria used in aquaculture, has demonstrated a great potential for use as an efficient MPs degrading bacterium in the biofloc farming system in the near future to guarantee a sustainable green aquaculture production.
