Microbial Electrosynthesis for Producing Medium Chain Fatty Acids Article

Na Chu, Wen Hao, Qinglian Wu, Qinjun Liang, Yong Jiang, Peng Liang, Zhiyong Jason Ren, Raymond Jianxiong Zeng

Engineering 2022, Volume 16, Issue 9,   Pages 141-153 doi: 10.1016/j.eng.2021.03.025

Abstract:

Microbial electrosynthesis (MES) employs microbial catalysts and electrochemistry to enhance CO2 bioconversion to organics with concurrent waste biorefining capability. The aim of this review is to comprehensively discuss the current state of the art and prospects of medium chain fatty acids (MCFAs) production in MES from CO2 and waste organics. Fundamental mechanisms and development of MCFAs production via conventional fermentation are introduced as well. Studies on MCFAs production in MES are summarized, highlighting the strategy of multiple-electron donors (EDs). Challenges for MCFAs production in MES from CO2 are presented, and the primary discussions included methanogenesis inhibition, adenosine triphosphate (ATP) limitations of acetogens, and production of limited EDs via solventogenesis. Possible applications of electrochemical approaches to promote the bioconversion of actual waste materials with MCFAs production are analyzed. Finally, future directions are explored, including multi-stage reactions, substrate supply, product extraction, and microbial pathways.

Diversity and distribution of proteorhodopsin-containing microorganisms in marine environments

Bo WEI

Frontiers of Environmental Science & Engineering 2012, Volume 6, Issue 1,   Pages 98-106 doi: 10.1007/s11783-010-0278-y

Abstract: Proteorhodopsin (PR) is a recently discovered protein involved in the utilization of light energy. Several studies have shown that PR-containing microorganisms are widespread and compose a large proportion of the biomass in marine ecosystems. A better understanding of the ecological role of PR will help clarify the effect of the global flow of energy and the carbon cycle on marine communities. In this study, a bioinformatical database of PR codon sequences, the Global Distribution Database of Proteorhodopsin (GDDP), as a tool for analyzing the diversity and distribution of PR-containing microorganisms in marine environments throughout the world was designed. The community structure of PR microorganisms were also compared using PCR assays and UniFrac analyses of 12 samples collected from three water layers (0, 75, and 200 m) at four representative sites in the Pacific, Atlantic, and Indian Oceans. The results indicate that PR-containing microorganisms can be grouped into two distribution types: widespread and location-specific. Representative cases of the former include SAR11-PR and HOT2C01-PR. Interestingly, PR communities cluster by geographic locale but not by water depth.

HEMIPTERAN-TRANSMITTED PLANT VIRUSES: RESEARCH PROGRESS AND CONTROL STRATEGIES

Frontiers of Agricultural Science and Engineering 2022, Volume 9, Issue 1,   Pages 98-109 doi: 10.15302/J-FASE-2021389

Abstract:

About 80% of plant viruses are transmitted by specific insect vectors, especially hemipterans with piercing-sucking mouthparts. Many virus-transmitting insects are also important crop pests that cause considerable losses in crop production. This review summarizes the latest research findings on the interactions between plant viruses and insect vectors and analyzes the key factors affecting insect transmission of plant viruses from the perspectives of insect immunity, insect feeding, and insect symbiotic microorganisms. Additionally, by referring to the latest applications for blocking the transmission of animal viruses, potential control strategies to prevent the transmission of insect-vectored plant viruses using RNAi technology, gene editing technology, and CRISPR/Cas9+ gene-driven technology are discussed.

Rapid control of black and odorous substances from heavily-polluted sediment by oxidation: Efficiency and effects

Kun Li, Min Yang, Jianfeng Peng, Ruiping Liu, Tista Prasai Joshi, Yaohui Bai, Huijuan Liu

Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 6, doi: 10.1007/s11783-019-1171-y

Abstract: Oxidants were proposed to rapidly control black and odorous substances in sediments. NaClO and KMnO4 had excellent efficiency to remove black and odorous substances. NaClO dramatically accelerated the release of organics, NH4+-N, P, and heavy-metals. Moderate oxidation had a limited effect on microbial communities. NaClO of 0.2 mmol/g was viewed to be the optimum option. The control of black and odorous substances in sediments is of crucial importance to improve the urban ecological landscape and to restore water environments accordingly. In this study, chemical oxidation by the oxidants NaClO, H2O2, and KMnO4 was proposed to achieve rapid control of black and odorous substances in heavily-polluted sediments. Results indicate that NaClO and KMnO4 are effective at removing Fe(II) and acid volatile sulfides. The removal efficiencies of Fe(II) and AVS were determined to be 45.2%, 94.1%, and 93.7%, 89.5% after 24-h exposure to NaClO and KMnO4 at 0.2 mmol/g, respectively. Additionally, rapid oxidation might accelerate the release of pollutants from sediment. The release of organic matters and phosphorus with the maximum ratios of 22.1% and 51.2% was observed upon NaClO oxidation at 0.4 mmol/g. Moreover, the introduction of oxidants contributed to changes in the microbial community composition in sediment. After oxidation by NaClO and KMnO4 at 0.4 mmol/g, the Shannon index decreased from 6.72 to 5.19 and 4.95, whereas the OTU numbers decreased from 2904 to 1677 and 1553, respectively. Comparatively, H2O2 showed a lower effect on the removal of black and odorous substances, pollutant release, and changes in sediment microorganisms. This study illustrates the effects of oxidant addition on the characteristics of heavily polluted sediments and shows that chemical oxidants may be an option to achieve rapid control of black and odorous substances prior to remediation of water environments.
