The increased global demand for plastic materials has led to severe waste pollution, particularly the marine environment. This critical issue affects both sea life and human beings since microplastics can enter food chain cause several health impacts. Plastic recycling, chemical treatments, incineration landfill are apparently not optimum solutions reducing pollution. Hence, this review presents two newly identified environmentally friendly approaches, biodegradation bioplastic production using algae, solve waste. Algae, microalgae, degrade through toxins systems or enzymes synthesized by microalgae itself while polymers as carbon sources. Utilizing algae been critically reviewed in paper demonstrate mechanism how affect algae. On other hand, algae-derived bioplastics have identical properties characteristics petroleum-based plastics, remarkably being biodegradable nature. provides new insights into different methods of producing algae-based (e.g., blending with genetic engineering), followed discussion on challenges further research direction increase their commercial feasibility.

The massive waste of poly(ethylene terephthalate) (PET) that ends up in the landfills and oceans needs hundreds years for degradation has attracted global concern. poor stability productivity available PET biocatalysts hinder their industrial applications. Active can provide a promising avenue bioconversion recycling. Therefore, there is an urgent need to develop new strategies could enhance stability, catalytic activity, solubility, productivity, re-usability these under harsh conditions such as high temperatures, pH, salinity. This raised great attention using bioengineering improve biocatalysts' robustness behavior. Herein, historical forecasting data plastic production disposal were critically reviewed. Challenges facing process be used solve them highlighted summarized. In this review, we also discussed recent progress enzyme approaches discovering biocatalysts, elucidating mechanism, improving performance, assess strength weakness highlighting gaps data. Discovery more potential hydrolases studying molecular mechanism extensively via solving crystal structure will widen research area move forward application. A deeper knowledge mechanisms give insight into future identification related enzymes. reported during review reduce crystallinity increase operational temperature hydrolyzing

Abstract Microplastic and nanoplastic contamination is widespread affects aquatic terrestrial ecosystems. Photosynthetic organisms are present in both media, they primary producers, sink for CO 2 , represent a major point of entry the food chain. Here, current knowledge on fate impacts microplastics nanoplastics interaction with these reviewed. As general trend, plastic characteristics (smaller size positive charge) play crucial role their toxicity toward photosynthetic organisms. Plastic leachates (containing additives) also source toxicity, some harmful compounds such as phthalate esters shown to accumulate plants generate risk consumers. Adsorption particles evidenced each type organism, uptake translocation nanoplastics, leading concerns trophic chain contamination. The available techniques detection secondary products biological samples media listed. Finally, gaps knowledge, specific challenges, future research directions discussed.

PETase displays great potential in PET depolymerization. Directed evolution has been limited to engineer due the lack of high-throughput screening assay. In this study, a novel fluorescence-based assay employing newly designed substrate, bis (2-hydroxyethyl) 2-hydroxyterephthalate (termed BHET-OH), was developed for hydrolases. The best variant DepoPETase produced 1407-fold more products towards amorphous film at 50 °C and showed 23.3 higher Tm value than WT. enabled complete depolymerization seven untreated wastes 19.1 g waste (0.4 % Wenzyme /WPET ) liter-scale reactor, suggesting that it is candidate industrial processes. molecular dynamic simulations revealed distal substitutions stabilized loops around active sites transmitted stabilization effect through enhancing inter-loop interactions network.
