The interplay between bacterial community composition and the environment determining function of inland water bacteria
bacterial community composition the environment determining function inland water bacteria
2014/4/16
We hypothesized that habitats differing in water flow regime would differ in bacterial function either because of differences in the local environment, in bacterial community composition (BCC), or in ...
Oxygen isotopic exchange and fractionation during bacterial ammonia oxidation
fractionation during bacterial ammonia oxidation Oxygen isotopic
2014/4/16
We examined the oxygen isotopic systematics for ammonia oxidation, the first step in the regeneration of
nitrate from ammonium. In particular, oxygen isotopic fractionation and exchange with water we...
Dynamics of organic-aggregate–associated bacterial communities and related environmental factors in Lake Taihu, a large eutrophic shallow lake in China
organic-aggregate–associated aihu a large eutrophic shallow lake
2014/4/16
To investigate the spatial and temporal variations of organic-aggregate–associated bacterial communities
(OABC), a 25-month observation was conducted at two contrasting sites (Meiliang Bay and the la...
Effect of Saharan dust inputs on bacterial activity and community composition in Mediterranean lakes and reservoirs
Effect of Saharan dust inputs bacterial activity community composition Mediterranean lakes and reservoirs
2014/4/18
We assessed the effects of Saharan dust inputs of particulate matter (PM), total phosphorus (TP), total nitrogen, and water soluble organic carbon (WSOC) on bacterial abundance (BA) in two alpine lake...
Effects of Tween 80 Pretreatment on Dry Matter Disappearance of Rice Straw and Cellulolytic Bacterial Adhesion
Tween 80 SDS Cellulolytic Bacteria Attachment Rice Straw
2016/5/3
An in situ experiment was conducted to find out whether Tween 80 improves rice straw digestion through increased adhesion of major fibrolytic bacteria. Rice straw was sprayed with various levels of Tw...
Bacterial Communities Developing during Composting Processes in Animal Manure Treatment Facilities
16S rRNA Gene Animal Manure Bacteria Composting PCR-DGGE
2016/4/29
We analyzed succession of the bacterial communities during composting of animal manure in three individual facilities. Polymerase chain reaction (PCR) and denaturing gradient gel electrophoresis (DGGE...
Analysis of the Structure of the Bacterial Community in the Livestock Manure-based Composting Process
Bacterial Community Compost Denaturing Gradient Gel Electrophoresis Manure
2016/4/28
We investigated the structure of bacterial communities present in livestock manure-based composting processes and evaluated the bacterial succession during the composting processes. Compost samples we...
Aging of allochthonous organic carbon regulates bacterial production in unproductive boreal lakes
allochthonous organic carbo production in unproductive
2014/4/18
We calculated average aquatic dissolved organic carbon (DOC) age (the time span from soil discharge to
observation) in water from the inlets and outlets of two unproductive Swedish lakes at different...
Bacterial diversity and morphology in deep ultraoligotrophic Andean lakes: Role of UVR on vertical distribution
Bacterial diversity morphology
2014/4/18
We investigated the community composition and the relative size–shape distribution of bacterial assemblages
in deep transparent lakes, where bacteria may be affected by harmful ultraviolet radiation ...
Organic matter diagenesis and bacterial contributions to detrital carbon and nitrogen in the Amazon River system
Organic matter diagenesis bacterial contributions
2014/4/18
Amino sugars and amino acids, including the bacterial biomarkers muramic acid and D-amino acids, were
measured to investigate the diagenetic alterations of and microbial contributions to detrital org...
Increased supply of ambient nitrogen has minimal effect on salt marsh bacterial production
Increased supply of ambient nitrogen salt marsh
2014/4/18
We examined the role of chronic low-level nutrient enrichment on the productivity of heterotrophic marsh
bacteria via a marsh fertilization experiment in which we mimicked the conditions of widesprea...
Seasonal changes of bacterial and archaeal communities in the dark ocean: Evidence from the Mediterranean Sea
bacterial and archaeal communities dark ocean
2014/4/17
The study site located in the northwestern Mediterranean Sea was visited nine times in 2005–2006 to collect
water samples from the epipelagic (5 m), mesopelagic (200 m, 600 m), and bathypelagic (1000...

bacterial lipids reflect central metabolic pathways Large D/H variations
2014/4/8
Large hydrogen-isotopic (D/H) fractionations between lipids and
growth water have been observed in most organisms studied to
date. These fractionations are generally attributed to isotope
effects i...
Nitrogen dynamics in the shallow groundwater of a riparian wetland zone of the Garonne, SW France: nitrate inputs, bacterial densities, organic matter supply and denitrification measurements
