Polystyrene and low-density polyethylene degradation by Bacillus cereus L1 isolated from plastic contaminated wastewater.
Article in Microbial cell factories, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe environmental disruption caused by enduring pollution has been aggravated by the excessive use of low-density polyethylene (LDPE) and polystyrene (PS) plastics due to their non-biodegradable composition. Microbial bioremediation could be an environmentally friendly approach to degrade these pollutants. In this research, plastic-degrading bacteria were isolated from plastic-polluted wastewater collected from a wastewater drain. METHODOLOGY: For this study, enrichment culture techniques were employed to isolate plastic-degrading bacteria from wastewater contaminated with plastic. Characterization was performed on the purified isolate with the highest efficiency. The bacteria utilizing PS and LDPE as the sole carbon sources were purified and characterized (FTIR, SEM) based on morphology, antibiotic resistance profile, and phylogenetic analysis through 16 S rRNA gene sequencing.
resultsThe bacteria showing the most significant PS and LDPE degradation were identified as B. cereus L1. The strain also exhibited biofilm-forming ability, confirmed by a qualitative crystal violet ring test, a pivotal factor in plastic breakdown. B. cereus L1 reduced the weight of LDPE beads from 1.08 g to 0.87 g and from 1.15 g to 0.92 g in four weeks. Fourier Transform Infrared Radiation (FTIR) spectroscopy revealed changes in the structural configuration of PS and LDPE after incubation with B. cereus L1, as distinct peaks at 2196 cm⁻¹ for alkynes, nitriles, and 1715 cm⁻¹ for carbonyl groups were observed, indicating the degradation of the polymers.
conclusionThis work highlights the potential of B. cereus L1 in bioremediation strategies for managing plastic waste, offering a sustainable and eco-friendly alternative for combating plastic pollution in both terrestrial and aquatic ecosystems.
