Reuterin-producing limosilactobacillus reuteri with glycerol metabolism ameliorates Staphylococcus aureus-induced intestinal inflammation and dysfunction without gut microbiota dependent

引用

Food Science and Human Wellness 2024年

作者： Jinmei li Kaixiang Zou xinrui li Ke Zhu Yijuan li Hua Wei Zhihong Zhang State Key Laboratory of Food Science and Resources， Nanchang University Sino-German Joint Research Institute， Nanchang University Chongqing Research Institute， Nanchang University

limosilactobacillus reuteri is a vertebrate symbiont that is widely appreciated as being of significant ecological importance for human health. As a unique feature， L. reuteri converts glycerol to the antimicrobial compound reuterin using enzymes encoded in its propanediol-utilization operon and evolves with host-driven diversification. Reuterin-producing L. reuteri HLRE13 was selectively isolated from poultry previously and confirmed to inhibit the growth of Staphylococcus aureus in vitro. However， it remains unclear whether L. reuteri HLRE13 retains these antagonistic properties when ingested in specific-pathogen-free mice. Here， we investigated the ameliorative effects and potential mechanisms of action of L. reuteri HLRE13 in combination with glycerol on S. aureus-induced infection phenotypes in mice. Firstly， our results confirmed that L. reuteri HLRE13 effectively inhibited the intestinal colonization of S. aureus CMCC26003; Secondly， L. reuteri HLRE13 combined with glycerol could alleviate the intestinal tissues damage caused by S. aureus through increasing the expression of ZO-1， Occludin and MUC-2， ameliorate the intestinal systemic inflammatory response， and maintain the balance of gut microbiota by increasing the relative abundance of Lactobacillus and reducing the relative abundance of Staphylococcus. Furthermore， the colonization resistance was also found on L. reuteri HLRE13 combined with glycerol against S. aureus in pseudo germ-free mice， and they exerted the similar effects on alleviating intestinal damage and improving immune function. Combining these results， we speculate that reuterin-producing L. reuteri antagonize S. aureus in mice without the gut microbiota-dependent manner. Overall， our findings will provide a theoretical foundation for the scientific cognition of L. reiteri in maintaining intestinal health by producing reuterin.

Asian Agricultural Research 2016年第2期8卷 19-27页

作者： Chengying HAN Zhenhong QI Dongmin ZHANG xinrui li College of Economics & Management Huazhong Agricultural University College of life Sciences & Technology Huazhong Agricultural University

China's extensive development model of pig industry gives rise to serious resource and environment bottleneck restriction,it is urgent to transform the existing development model into ecological farming model. In this process,farmers' behavior will play a key role. On the basis of summarizing development connotation and characteristics of ecological agriculture,using survey data of 323 pig farmers in 6 provinces,based on the Theory of Planned Behavior( TPB) it introduced individual characteristics and external environment constraint variables,and made an empirical analysis on factors influencing intention and behavior of pig farmers' ecological farming using the Structural Equation Model( SEM). Results indicate:( i) ecological farming intention of pig farmers has the largest direct effect on their ecological farming behavior;( ii)ecological farming cognition of pig farmers has significant positive effect on their ecological farming behavior;( iii) external environment has the largest indirect effect on their ecological farming behavior,followed by the overall effect,and external environment has significant positive effect on ecological farming attitude and cognition of pig farmers;( iv) individual characteristics( educational level and income level) of pig farmers influence ecological farming behavior of pig farmers through their ecological farming attitude and intention,but the degree of influence is limited.

Regional Carbon Emission Performance of Pig Production in China according to Malmquist-DEA Approach

引用

Asian Agricultural Research 2017年第6期9卷 55-60,66页

作者： Wenbin WANG Zhenhong QI xinrui li Lanya WU College of Economics and Management Huazhong Agricultural University HubeiRuralDevelopmentResearchCenter

As pig production is a main contributor of greenhouse gas(GHG) emissions from livestock sector,the carbon emissions of pig production are attracting increasing attention,especially in the developing countries. Based on the panel data of 30 provinces in China from 2001 to 2012,this paper measures the provincial carbon emission performance(CEP) of pig production and we use a Malmquist DEA approach to analyze the decomposition which includes desirable and undesirable output. Furthermore,the regional disparity in carbon emission performance of pig production is also analyzed and finally the convergence is tested. The main results are as follows:(i) there are provincial differences in carbon emission performance changing of pig production in China,and the carbon emission performance of pig production in 30 provinces has a downward trend during this period;(ii) among China’s three major economic regions,in terms of carbon emission performance of pig production,they are ranked in descending order as follows: Western China,Central China and Eastern China;(iii) convergence testing shows that there is a convergence trend for carbon emission performance both nationally and for the three regions.
