Bacterial production and extracellular degradation of polyesters
Health and environmental sciences Pure sciences Biological sciences Degradation Extracellular Polyesters Pseudomonas oleovorans Comamonas Bacterial production
2015/1/28
Poly(β-hydroxyalkanoates), PHAs, are thermoplastic polyesters, which have potential for use as biodegradable plastics. The material properties of PHAs depend upon their chemical structure. Pseudomonas...
Ultrahigh bacterial production in a eutrophic subtropical Australian river: Does viral lysis short-circuit the microbial loop?
short-circuit the microbial loop Ultrahigh bacterial production
2014/4/8
We studied trophic dynamics in a warm eutrophic subtropical river (Bremer River, Australia) to determine
potential sources of dissolved organic carbon (DOC) and the fate of heterotrophic bacterial pr...
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...
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...
Factors limiting heterotrophic bacterial production in the southern Pacific Ocean
Factors heterotrophic bacterial production southern Pacific Ocean
2010/1/15
The role of potential factors limiting bacterial growth was investigated along vertical and longitudinal gradients across the South Eastern Pacific Gyre. The effects of glucose, nitrate, ammonium and ...
Dissolved organic matter and bacterial production and respiration in the sea-surface microlayer of the open Atlantic and the western Mediterranean Sea
Dissolved organic matter bacterial production respiration the sea-surface microlayer Atlantic the western Mediterranean Sea
2014/4/21
The sea-surface microlayer (SML) is the boundary layer between the ocean and the atmosphere. We measured bacterial production and respiration along with dissolved organic carbon (DOC), nitrogen (DON),...
Heterotrophic bacterial production in the eastern South Pacific:longitudinal trends and coupling with primary production
Heterotrophic bacterial production eastern South Pacific longitudinal trends primary production
2010/1/15
Spatial variation of heterotrophic bacterial production and phytoplankton primary production were investigated across the eastern South Pacific Ocean (−141° W, −8° S to −72° W, ͨ...

Methanotrophic activity in relation to methane efflux and total heterotrophic bacterial production in a stratified, humic, boreal lake
humic boreal lake
2014/5/4
We studied methanotrophic activity in the water column in relation to heterotrophic bacterial production and efflux of methane (CH4) from the lake surface in a small, stratified, humic, boreal lake (V...

2014/5/21
The importance of organic carbon and inorganic nutrients in controlling bacterial production was investigated in
two tropical lowland rivers draining undisturbed forested catchments. Glucose (C), amm...
