Study on the microbial community structure, diversity and abundance in water-soil interface sediments on the watershed of three rivers [PDF]
, 2013 为了探讨无机盐分、养分及有机质矿化作用对微生物群落结构、多样性和功能微生物丰度影响，河流水土界面微生物群落结构和碳、氮、硫循环功能微生物种群的演替规律，本论文以九龙江、闽江和瓯江三江流域作为研究区域，并增加温室培养实验，对其中水土界面沉积物样品中的理化参数、微生物群落、多样性和功能微生物丰度进行测定；采用基因文库构建技术、变性梯度凝胶电泳技术（DGGE）和illumina高通量测序技术分析了样品中微生物群落结构及活动规律；利用实时荧光定量PCR（RT-PCR）技术对功能微生物进行定量 ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Root exudates play a key role as signals and nutrients in mediating plant–microbe communication. However, critical knowledge gaps remain regarding how root exudates mediate soil–microbe–plant interactions to regulate crop yield under long‐term straw mulching combined ...

Study on microbial community responses and dissolved organic matter (DOM) transformations in coastal surface seawater amended with sedimentary DOM in Xiamen [PDF]
, 2016 海洋沉积物是海水溶解有机质（Dissolvedorganicmatters，DOM）的重要来源。DOM作为海洋异养微生物生存的主要物质和能量来源，影响着微生物群落的结构，而微生物群落也同时影响着DOM的化学组成和最终命运。近年来，海洋沉积物DOM成为海洋生物地球化学领域的热点研究对象，但其生物可利用性一直存在争议，且沉积物DOM释放到上层水体后将如何影响微生物群落的结构也不清晰。为了研究沉积物DOM的生物可利用性，以及沉积物DOM与上层海水微生物群落之间的相互关系，本论文采集了厦门近岸沉积物表层DOM ...

Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Isolation of natural products and fermentation optimization of marine antifouling active bacteria [PDF]
, 2016 海洋生物污损对海中人工设施造成严重危害，传统重金属防污剂如有机锡和氧化亚铜等因其毒性相继被禁用或限用，急需开发新型环保防污剂，其中海洋生物体内的防污损活性物质是重要来源。但海洋动植物中的防污损活性物质通常含量低，严重限制其开发利用。微生物可通过发酵进行规模化培养，有利于解决天然防污损产物在量上的难题。另外，海洋生物的体表微生物在防御体表污损中起到重要作用。对海洋生物体表微生物进行鉴定和防污损活性物质研究，不仅为揭示海洋微生物与海洋污损生物之间的化学生态关系和相互作用提供新的研究资料 ...

微生物由来リパーゼ活性のスクリーニング : 食用キノコを中心とした担子菌類由来リパーゼの探索 [PDF]
, 2020 キノコに代表される担子菌類は，食用や漢方など，古くから食品や医薬品として利用されてきた。しかしながら，その他の利用，特に，有用物質生産を目的とした「生体触媒」としての有用性については，ほとんど知られていなかった。そこで，本研究では，食用キノコを中心とした担子菌類の，生体触媒としての可能性を探るため，担子菌由来の細胞外分泌型リパーゼの探索を目的として研究を行った。Basidiomycetes containing edible mushrooms have been used for foods and ...

The underappreciated roles of fog and dew on vegetation and biocrusts
New Phytologist, EarlyView.Summary Fog and dew represent minor components of ecosystem water budgets in most ecosystems. However, fog and dew can play an essential role in ecosystem dynamics and are particularly important for water‐limited systems. In addition to serving as direct water inputs, fog and dew can influence microclimate and water redistribution, thereby promoting ...

Bioreduction-assisted fabrication of Pd-based nanomaterials and their catalytic applications [PDF]
, 2015 由于植物或微生物还原法在制备贵金属纳米材料具有绿色、环保等优点，因而备受研究者关注。其中，利用植物提取液还原法制备纳米材料，植物来源易得，操作简单便捷；而微生物表面的官能团可以吸附和固定金属离子，表面分子的多样性和结构的复杂性，使得微生物可以作为有效模板制备或自组装新颖的纳米结构材料，因此，生物还原法已成为纳米材料制备的一个重要研究方向。为此，本论文研究了微生物法和植物还原法两部分内容。微生物法选择培养生物量比较高的真核生物--毕赤酵母菌为生物吸附剂和还原剂 ...

Veterinary Dermatology, Volume 37, Issue 3, Page 353-364, June 2026.ABSTRACT Background Canine atopic dermatitis (cAD) is a multifactorial, inherited skin disease, estimated to affect ≤ 15% of dogs. Studies of skin messenger mRNA in cAD currently use invasive methods, including blood sampling and biopsy collection, whilst advances in human atopic dermatitis study methodology have demonstrated reliable use of minimally ...
