Construction of microbial consortia for microbial degradation of complex compounds

Frontiers in Bioengineering and Biotechnology, Journal Year: 2022, Volume and Issue: 10

Published: Dec. 6, 2022

Increasingly complex synthetic environmental pollutants are prompting further research into bioremediation, which is one of the most economical and safest means restoration. From current research, using microbial consortia to degrade compounds more advantageous compared isolated bacteria, as former adaptable stable within growth environment can provide a suitable catalytic for each enzyme required by biodegradation pathway. With development biology gene-editing tools, artificial systems be designed efficient, stable, robust, they used produce high-value-added products with their strong degradation ability. Furthermore, shown promising in compounds. In this review, strategies constructing robust discussed. The advances also classified detailed, including plastics, petroleum, antibiotics, azo dyes, some present sewage. Thus, paper aims support helps those who focus on consortia.

Microplastic pollution in the marine environment: A review

Journal of Hazardous Materials Advances, Journal Year: 2023, Volume and Issue: 10, P. 100327 - 100327

Published: May 1, 2023

The quantity of plastic materials produced worldwide is progressively increasing. For instance, annual global production has increased from 1.5 to 390.7 million metric tons 1950 2021. Meanwhile, inefficient management strategies have resulted in huge waste disposal (i.e., the form macro-, micro-, and nanoplastics) environment a hostile manner. In particular, such uncontrollable discarding paves entrance pollution into as microplastics (μPs) after degradation macroplastics. this respect, marine environments are most typical regions prone μP pollution. These ubiquitous emerging pollutants can also adsorb other pollutants, organic materials, toxic heavy metal ions, pathogens, transfer them living organisms. main theme present study compile information on how affects ecosystem, with particular emphasis following key factors: (i) types sources μPs, particularly those entering sinks; (ii) mechanisms leading μPs' degradation; (iii) poisonous effects μPs biota humans; (iv) fate environment, including their transportation routes deposition modes, (v) recent developments characterization, separation, removal environment. presented here would be practical for developing effective risk plans.

Beyond Microbial Biodegradation: Plastic Degradation by Galleria mellonella

Journal of Polymers and the Environment, Journal Year: 2023, Volume and Issue: 32(5), P. 2158 - 2177

Published: Nov. 17, 2023

Abstract One of the major environmental issues that modern civilizations are currently dealing with is growing amount plastic waste. Because how they affect all forms life, this waste seen as a severe worldwide issue. Current methods for disposal do not offer definitive solutions and often lead to production microplastics or secondary pollution. In recent years there has been interest by scientific community in degradation plastics biological means, particular possibilities using insects potential solution accumulation type have investigated. Among these, one most promising undoubtedly lepidopteran Galleria mellonella , which synthesizes first ever discovered polyethylene degrading enzymes. review we propose an overview polymers common methodologies, analyses current state art about carried out insect.

Designing biodegradable alternatives to commodity polymers

Chemical Society Reviews, Journal Year: 2023, Volume and Issue: 52(23), P. 8085 - 8105

Published: Jan. 1, 2023

The development and widespread adoption of commodity polymers changed societal landscapes on a global scale. Without the everyday materials used in packaging, textiles, construction medicine, our lives would be unrecognisable. Through decades use, however, environmental impact waste plastics has become grimly apparent, leading to sustained pressure from environmentalists, consumers scientists deliver replacement materials. need reduce is beyond question, yet reality replacing these ubiquitous with sustainable alternatives complex. In this tutorial review, we will explore concepts design biodegradability, as applied synthetic intended for use at We provide an overview potential biodegradation pathways available different environments, highlight importance considering when designing new identify gaps collective understanding production, fate biodegradable polymers: identifying appropriate feedstock materials, changes needed production recycling practices, improving produce. discuss current standard methods determination where lengthy experimental timescales often frustrate develop better tools models assess degradation rate environments.
