Extracellular polymeric substances (EPS) contribute to biofilm stability and adhesion properties. The EPS matrix might also be a site for free extracellular enzyme activity; however, little is known about participation of enzyme activity in...
Effect of antibiotic therapy on human fecal microbiota and the relation to the development of Clostridium difficile [0.03%]
抗生素治疗对人类粪便微生物群的影响及其与艰难梭菌感染发生的关系

The gastrointestinal tract is a complex ecosystem. Recent studies have shown that the human fecal microbiota is composed of a consortium of microorganism. It is known that antibiotic treatment alters the microbiota, facilitating the prolife...
Evidence that ammonia-oxidizing archaea are more abundant than ammonia-oxidizing bacteria in semiarid soils of northern Arizona, USA [0.03%]
氨氧化古菌比氨氧化细菌更适应美国亚利桑那州半干旱土壤的证据

Autotrophic ammonia-oxidizing communities, which are responsible for the rate-limiting step of nitrification in most soils, have not been studied extensively in semiarid ecosystems. Abundances of soil archaeal and bacterial amoA were measur...
Elevated aluminium concentration in acidified headwater streams lowers aquatic hyphomycete diversity and impairs leaf-litter breakdown [0.03%]
酸化山溪中的铝含量偏高会降低水生丝膜菌的多样性并影响叶片碎裂作用

We investigated the network relationships of bacteria in a structurally stable mixed culture degrading cellulose. The mixed culture consists of four bacterial strains (a cellulose-degrading anaerobe [strain S], a saccharide-utilizing anaero...
Phylogenetic diversity and spatial distribution of the microbial community associated with the Caribbean deep-water sponge Polymastia cf. corticata by 16S rRNA, aprA, and amoA gene analysis [0.03%]
基于16S rRNA,aprA和amoA基因分析的加勒比深水海绵Polymastia cf. corticata相关微生物群落的系统发育多样性及空间分布

Denaturing gradient gel electrophoresis (DGGE)-based analyses of 16S rRNA, aprA, and amoA genes demonstrated that a phylogenetically diverse and complex microbial community was associated with the Caribbean deep-water sponge Polymastia cf. ...
Presence of quorum-sensing systems associated with multidrug resistance and biofilm formation in Bacteroides fragilis [0.03%]
不动杆菌脆弱株与多药耐药和生物被膜形成相关的群体感应系统的存在性研究
