Introduction Microplastics (MPs) are widely distributed in the environment, causing damage to biota and human health. Due their physicochemical characteristics, they become resistant particles environmental degradation, leading accumulation large quantities terrestrial ecosystem. Thus, there is an urgent need for measures mitigate such pollution, with biological degradation being a viable alternative, where bacteria play crucial role, demonstrating high efficiency degrading various types of MPs. Therefore, study aimed identify potential MP biodegradation enzymes produced during process. Methods The methodology used followed Preferred Reporting Items Systematic Reviews Meta-Analyses (PRISMA) protocol. Results Discussion research yielded 68 eligible studies, highlighting from genera Bacillus , Pseudomonas Stenotrophomonas Rhodococcus as main organisms involved biodegradation. Additionally, hydrolases alkane hydroxylases were emphasized involvement this bacterial promising pathway impact MPs, relevance identifying biotechnological large-scale applications reducing pollution.

This work aims to enhance the adsorption performance of Laponite @diatomite for organic pollutants by modifying it with cetyltrimethylammonium bromide (CTAB). The microstructure and morphology CTAB-modified material were characterized using SEM, XRD, FTIR, BET, TG. Furthermore, influences key parameters, containing pH, adsorbent dosage, reaction time, temperature, on process investigated. kinetics, thermodynamics, isotherm models analyzed. Finally, potential mechanisms given based characterization. research findings indicate that CTAB-La@D exhibits good toward Congo red (CR) over a broad pH range. maximum capacity CR was 451.1 mg/g under optimum conditions (dosage = 10 mg, contact time 240 min, initial concentration 100 mg/L, temperature 25 °C, 7). conformed pseudo-second-order kinetic model, isotherms indicated more in line Langmuir physical adsorption. Thermodynamic analysis illustrates is exothermic spontaneous. Additionally, electrostatic hydrophobic effect investigated through XPS FTIR analysis. provides an effective pathway designing high-performance adsorbents removal dye, synthesized materials hold great capability practical utilization treatment wastewater.
