| 1 | Response of microbial communities to biochar-amended soils:a critical review显示文摘Application of biochar to soils changes soil physicochemical properties and stimulates the activities of soil microorganisms that influence soil quality and plant performance.Studying the response of soil microbial communities to biochar amendments is important for better understanding interactions of biochar with soil,as well as plants.However,the effect of biochar on soil microorganisms has received less attention than its influences on soil physicochemical properties.In this review,the following key questions are discussed:(i)how does biochar affect soil microbial activities,in particular soil carbon(C)mineralization,nutrient cycling,and enzyme activities?(ii)how do microorganisms respond to biochar amendment in contaminated soils?and(iii)what is the role of biochar as a growth promoter for soil microorganisms?Many studies have demonstrated that biochar-soil application enhances the soil microbial biomass with substantial changes in microbial community composition.Biochar amendment changes microbial habitats,directly or indirectly affects microbial metabolic activities,and modifies the soil microbial community in terms of their diversity and abundance.However,chemical properties of biochar,(especially pH and nutrient content),and physical properties such as pore size,pore volume,and specific surface area play significant roles in determining the efficacy of biochar on microbial performance as biochar provides suitable habitats for microorgan-isms.The mode of action of biochar leading to stimulation of microbial activities is complex and is influenced by the nature of biochar as well as soil conditions. | Kumuduni Niroshika Palansooriya James Tsz Fung Wong Yohey Hashimoto Longbin Huang Jörg Rinklebe Scott X.Chang Nanthi Bolan Hailong Wang Yong Sik Ok | 2019 | Biochar2019，1，1： | 34 |
| 2 | Arbuscular mycorrhiza and plant chromium tolerance显示文摘Arbuscular mycorrhizal(AM)fungi are ubiquitous soil fungi that form symbiotic associations with most terrestrial plants.The growth and functions of AM fungi depend on carbohydrates supplied by the plants,in return,the fungi assist the plants to acquire mineral nutrients(e.g.,phosphorus)from soil.The AM symbiosis also improves plant survival in various unfavorable environments,such as metal(loid)contaminated soil.It has been well demonstrated that AM symbiosis improved plant adaptation to Cr contamination,which would have a great potential in phytoremediation and ecological restoration of Cr contaminated soils.In this paper,we have reviewed the role of AM fungi in alleviation of Cr phytotoxicity and associated factors influencing plant Cr tolerance.AM symbiosis improves plant Cr tolerance through its direct roles in Cr stabilization and transformation and indirect roles via AM symbiosis mediated nutrient acquisition and physiological regulation.Future research on physiological and molecular mechanisms underlying Cr behavior and detoxification in AM symbiosis,as well as potential use of AM fungi in ecological restoration and agriculture production in Cr contaminated soils were also proposed. | Songlin Wu Xin Zhang Longbin Huang Baodong Chen | 2019 | Soil Ecology Letters2019，1，3： | 3 |
| 3 | Diversity of As Metabolism Functional Genes in Pb-Zn Mine Tailings显示文摘Microbial activities impact arsenic(As) transformation in mine tailings substantially, yet little is understood on the functional diversity of As metabolism genes. This study explored this issue using a metagenomic approach coupled by a local BLASTN procedure established in our recent studies. An assembled metagenome, recovered from hypersaline and sulfidic mine tailings, was screened for As metabolism genes aio A, arr A, ars C and ars M. This was done using a local BLASTN procedure against databases of the As metabolism genes built in this study. Putative As metabolism genes detected in the assembled metagenome included 11 ars M, 20 ars C and 1 arr A full-length sequences. Together with the rRNA-based phylogenetic profiling results, a picture depicting microbial As cycling in the tailings to the genus level was obtained. It was found that most of the dominant genera in the tailings potentially harboured the genes for As reduction and/or methylation. In particular, a typical pyrite-eater present in the tailings, Thioalkalivibrio sp., was found to harbour not only ars C and ars M, but also arr A. These results highlight the unexpected diversity of As metabolism genes in the tailings, especially considering the extremely low species diversity therein. The microbial As cycling picture established here has potential use for guiding the purposeful manipulation of As biogeochemistry in the tailings. | LI Xiaofang Philip L.BOND Longbin HUANG | 2017 | Pedosphere2017，27，3： | 3 |

| 7 | Decrypting the Influence of Axial Coordination on the Electronic Microenvironment of Co-N_(5)Site for Enhanced Electrocatalytic Reaction显示文摘Metal porphyrins are star molecules that possess welldefined coordination metal centers for versatile catalytic reactions.However,most previous work has focused on the correlations between in-plane symmetric configuration of metal-N_(4)sites and their catalytic performance.Addressing the catalytic contribution of additional axial coordination to such symmetric configuration remains a challenge.Theoretical calculations revealed that axially anchoring an extra pyridine on the tetra-coordinated cobalt porphyrin(Co-N4)to construct penta-coordinated cobalt porphyrin(Co-N_(5))renders cobalt a higher electron density,thereby favoring the rate-determining O_(2)adsorption/activation and reducing the oxygen electroreduction barrier.Therefore,a well-defined Co-N_(5)site is rationally introduced into the azo-linked polymer framework for a fundamental structure-catalytic performance correlation study.As-prepared Co-N_(5)catalyst exhibits a 26 mV positive shift in half-wave potential compared with the pyridine-free Co-N_(4)counterpart,discloses a markedly higher power density(141.4 mW cm^(−2)),and possesses better long-term durability(over 160 h cycles)in a Zn-air battery.Moreover,such a Co-N_(5)catalyst also showcases potential applications for CO_(2)reduction with high CO_(2)-to-CO conversion faradic efficiency and better selectivity than the Co-N_(4)counterpart because coordination of the fifth pyridine evokes electronic localization that suppresses a competitive side reaction.This work proves the positive electrocatalytic contribution of axial penta-coordination on well-defined metalporphyrin-based catalysts and offers atomic understanding of the structure-performance correlation on single atom catalysts for future catalyst design. | Bingyu Huang Senhe Huang Chenbao Lu Longbin Li Judan Chen Ting Hu Dirk Lützenkirchen-Hecht Kai Yuan Xiaodong Zhuang Yiwang Chen | 2023 | CCS Chemistry2023，5，8： | 0 |
