Revealing organic carbon sources fueling a coral reef food web in the Gulf of Mexico using stable isotopes and fatty acids
Revealing organic carbon sources coral reef food web Gulf of Mexico stable isotopes fatty acids
2014/4/2
Carbon and nitrogen stable isotopes and fatty acids (FAs) revealed primary producer organic carbon sources that fuel a coral reef food web with river influence. A stable isotope mixing model was used ...
Isotope enrichment in mangrove forests separates microphytobenthos anddetritus as carbon sources for animals
Isotope enrichment mangrove ests separates microphy tobenthos anddetritus carbon sources animals
2014/4/16
Microphytobenthos (MPB) and mangrove detritus were labeled with a carbonisotope (13C) in separate experiments to quantify their contributions to the nutrition of major faunal components within a mangr...
Role of Ethanol in Improvement of Bacterial Cellulose Production: Analysis Using 13C-Labeled Carbon Sources
bacterial cellulose cellulose production acetic acid bacteria
2009/6/18
We studied the role of ethanol in the improvement of bacterial cellulose (BC) production, primarily using 13C NMR. 13C-labeled BC was biosynthesized by Acetobacter xylinum ATCC 10245 using culture med...
Effect of Nitrogen and Carbon Sources on Lipase Production by Penicillium aurantiogriseum
lipases Penicillium aurantiogriseum media optimization
2009/3/19
A wild fungal strain isolated from soybean oil and identified as Penicillium aurantiogriseum initially presented a volumetric lipase activity of 0.4 U/mL in submerged culture in a medium containing 0....
The impact of biogenic carbon sources on aerosol absorption in Mexico City
biogenic carbon sources aerosol absorption Mexico City
2009/3/13
In order to determine the wavelength dependence of fine (<1 micron) atmospheric aerosol absorption in the Mexico City area, the absorption Ångstrom exponents (AAEs) were calculated from hourly a...
Alternative Carbon Sources from Sugar Cane Process for Submerged Cultivation of Cunninghamella bertholletiae to Produce Chitosan
chitosan Cunninghamella bertholletiae submerged culture
2009/3/9
A mucoralean strain of Cunninghamella bertholletiae was used to evaluate the influence of culture medium on chitosan production. In the traditional medium for the growth of mucoralean strains, constit...
Effect of carbon sources, substrates, leachates, and water grades on germinability of Phomopsis vexans
Phomopsis blight Phomopsis vexans brinjal
2009/3/4
The five isolates of the pathogen Phomopsis vexans formed both types of conidia i.e. a and b conidia. Both the conidia were exposed to plant parts, plant leachates, and different grades of water...
Consideration of betaine and one-carbon sources of N5-methyltetrahydrofolate for use in homocystinuria and neural tube defects1,2
Betaine methyltetrahydrofolate homocystinuria neural tube defects
2008/12/12
A major focus in attempts to ameliorate homocystinuria and neural tube defects is supplementation of the diet with B vitamins. The metabolic defect in these cases may be due in part to a deficiency of...
Direct measurement of thed13 C signature of carbon respired by bacteria in lakes: Linkages to potential carbon sources, ecosystem baseline metabolism, andCO2fluxes
the d13 C signature bacteria in lakes potential carbon sources ecosystem baseline metabolism CO2 fluxes
2014/4/18
Using a novel method to measure the isotopic signature (d13C) of respiratory CO2 produced by bacterioplankton, we determined the proportion of terrigenous vs. algal-derived organic carbon (OC) respire...
Proteinase Activity of Pseudomonas fluorescens Grown in Cold Milk Supplemented with Nitrogen and Carbon Sources
extracellular proteinase production Pseudomonas intracellular adenosine triphosphate milk supplementation
2008/3/22
Extracellular proteinase activity varied when Pseudomonas fluorescens was grown at 7°C in UHT milk supplemented with different substrates. Addition of glutamine (5 mM) and glutamic acid (10 mM) reduce...
