Engineered Living Materials For Sustainability

Chemical Reviews, Journal Year: 2022, Volume and Issue: 123(5), P. 2349 - 2419

Published: Dec. 13, 2022

Recent advances in synthetic biology and materials science have given rise to a new form of materials, namely engineered living (ELMs), which are composed matter or cell communities embedded self-regenerating matrices their own artificial scaffolds. Like natural such as bone, wood, skin, ELMs, possess the functional capabilities organisms, can grow, self-organize, self-repair when needed. They also spontaneously perform programmed biological functions upon sensing external cues. Currently, ELMs show promise for green energy production, bioremediation, disease treatment, fabricating advanced smart materials. This review first introduces dynamic features systems potential developing novel We then summarize recent research progress on emerging design strategies from both perspectives. Finally, we discuss positive impacts promoting sustainability key future directions.

Electroactive Bacteria in Natural Ecosystems and Their Applications in Microbial Fuel Cells for Bioremediation: A Review

Microorganisms, Journal Year: 2023, Volume and Issue: 11(5), P. 1255 - 1255

Published: May 10, 2023

Electroactive bacteria (EAB) are natural microorganisms (mainly Bacteria and Archaea) living in various habitats (e.g., water, soil, sediment), including extreme ones, which can interact electrically each other and/or with their extracellular environments. There has been an increased interest recent years EAB because they generate electrical current microbial fuel cells (MFCs). MFCs rely on able to oxidize organic matter transfer electrons anode. The latter flow, through external circuit, a cathode where react protons oxygen. Any source of biodegradable be used by for power generation. plasticity electroactive exploiting different carbon sources makes green technology renewable bioelectricity generation from wastewater rich carbon. This paper reports the most applications this promising wastewater, sediment recovery. performance terms measurements electric power), electron mechanisms EAB, MFC studies aimed at heavy metal contaminant bioremediationF all described discussed.

Interactions among microorganisms functionally active for electron transfer and pollutant degradation in natural environments

Eco-Environment & Health, Journal Year: 2023, Volume and Issue: 2(1), P. 3 - 15

Published: Jan. 28, 2023

Compared to single microbial strains, complex interactions between consortia composed of various microorganisms have been shown be effective in expanding ecological functions and accomplishing biological processes. Electroactive (EMs) degradable (DMs) play vital roles bioenergy production the degradation organic pollutants hazardous human health. These can strongly interact with other promote metabolic cooperation, thus facilitating electricity pollutant degradation. In this review, we describe several specific types EMs DMs based on their ability adapt different environments, summarize mechanism extracellular electron transfer. The effects are evaluated terms efficiency. principle enhancement is also introduced, such as improved biomass, changed pathways, biocatalytic potentials, which directly or indirectly conducive

Quorum Sensing Enhances Direct Interspecies Electron Transfer in Anaerobic Methane Production

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(6), P. 2891 - 2901

Published: Feb. 3, 2024

Direct interspecies electron transfer (DIET) provides an innovative way to achieve efficient methanogenesis, and this study proposes a new approach upregulate the DIET pathway by enhancing quorum sensing (QS). Based on long-term reactor performance, QS enhancement achieved more vigorous methanogenesis with 98.7% COD removal efficiency. In control system, failure occurred at accumulated acetate of 7420 mg COD/L lowered pH 6.04, much lower 41.9% was observed. The significant in QS-enhancing system supported higher expression conductive pili c-Cyts cytochrome secretion-related genes, resulting 12.7- 10.3-fold improvements. Moreover, also improved energy production capability, increase F-type V/A-type ATPase 6.3- 4.2-fold, effect probably provided for nanowires secretion. From perspective community structure, increased abundance Methanosaeta Geobacter from 54.3 17.6% 63.0 33.8%, respectively. Furthermore, genes involved carbon dioxide reduction alcohol dehydrogenation 0.6- 7.1-fold, Taken together, indicates positive effects chemicals stimulate advances understanding environments such as anaerobic digesters sediments.
