Zeolite membranes offer outstanding potentials in separation of many molecular mixtures due to their molecular sieving selectivity and the high thermal and mechanical stability that allow them to operate at harsh *** of durable and high separation performance membranes with lower fabrication and operation cost are highly demanded for industrial applications. Zeolite T membrane possesses good acid-resistance with excellent hydrophilic properties as compared to NaA zeolite membrane and can be extended to industrial organic dehydrations under an acidic environment. In the present review the research advances in development of zeolite T membranes for the dehydration of organic mixtures in acidic conditions are summarized. Especially the low temperature synthesis, and epitaxial growth of the zeolite membrane with high performance are well addressed, besides emphasis is particularly placed on ensemble synthesis of hollow fiber zeolite T membrane module and its future prospects for industrial separations.

由土传病原菌引起的作物病害频发制约着世界农业的可持续发展。以根际微生物群落这一生物屏障为核心的根际免疫在抵御土传病原菌入侵中发挥着至关重要的作用。除竞争营养、产生抗生物质等外,根际微生物还通过分泌易挥发性有机物(Microbial volatile organic compounds,mVOCs)与病原菌、其他土著微生物以及宿主植物互作,以更好地适应根际环境和发挥抑病功能。由于具有作用浓度低、可在水-土-气等多界面自由迁移和长距离传播等优势,mVOCs日益成为根际免疫领域机理研究和产品开发的热点。本文首先介绍mVOCs参与土壤抑菌性的发现过程,系统梳理抑制土传病原菌的mVOCs及分泌源--有益微生物。其次,从抑制土传病原菌生长和致病、调控微生物群落互作以及激发植物抗性3个方面阐述mVOCs提升根际免疫的作用机理。随后,总结mVOCs在防控土传病害中的应用现状,并分析影响mVOCs产生和作用效果的土壤生物和非生物因素。最后,提出与根际免疫相关的mVOCs研究思考,呼吁关注mVOCs在根际免疫领域的理论和实践价值。

Plant growth-promoting rhizobacteria(PGPR) are considered to be the most promising agents for cash crop production via increasing crop yields and decreasing disease occurrence. The Bacillus amyloliquefaciens strain W19 can produce secondary metabolites(iturin and bacillomycin D) effectively against Fusarium oxysporum f. sp. cubense(FOC). In this study, the ability of a bio-organic fertilizer(BIO) containing strain W19 to promote plant growth and suppress the Fusarium wilt of banana was evaluated in both pot and field experiments. The results showed that application of BIO significantly promoted the growth and fruit yield of banana while suppressing the banana Fusarium wilt disease. To further determine the beneficial mechanisms of the strain, the colonization of green fluorescent protein-tagged strain W19 on banana roots was observed using confocal laser scanning microscopy and scanning electron microscopy. The effect of banana root exudates on the formation of biofilm of strain W19 indicated that the banana root exudates may enhance colonization. In addition, the strain W19 was able to produce indole-3-acetic acid(IAA), a plant growth-promoting *** results of these experiments revealed that the application of strain W19-enriched BIO improved the banana root colonization of strain W19 and growth of banana and suppressed the Fusarium wilt. The PGPR strain W19 can be a useful biocontrol agent for the production of banana under field conditions.

Coupling of the chemical niche and microbiome in the rhizosphere:implications from watermelon grafting

Frontiers of Agricultural Science and Engineering 2016年第3期3卷 249-262页

Grafting is commonly used to overcome soilborne diseases. However, its effects on the rhizodeposits as well as the linkages between the rhizosphere chemical niche and microbiome remained unknown. In this paper,significant negative correlations between the bacterial alpha diversity and both the disease incidence(r = – 0.832,P = 0.005) and pathogen population(r = – 0.786, P = 0.012)were detected. Moreover, our results showed that the chemical diversity not only predicts bacterial alpha diversity but also can impact on overall microbial community structure(beta diversity) in the ***, some anti-fungal compounds including heptadecane and hexadecane were identified in the rhizosphere of grafted watermelon. We concluded that grafted watermelon can form a distinct rhizosphere chemical niche and thus recruit microbial communities with high diversity. Furthermore, the diverse bacteria and the antifungal compounds in the rhizosphere can potentially serve as biological and chemical barriers, respectively, to hinder pathogen invasion. These results not only lead us toward broadening the view of disease resistance mechanism of grafting, but also provide clues to control the microbial composition by manipulating the rhizosphere chemical niche.
