Aspergillus nidulans can utilize carbon sources that result in the production of TCA cycle intermediates, thereby requiring gluconeogenesis. We have cloned the acuG gene encoding fructose-1,6 bisphosphatase and found that expression of this gene is regulated by carbon catabolite repression as well as by induction by a TCA cycle intermediate similar to the induction of the previously studied acu...
Greenhouse gases (GHG) are a serious threat to humans and environment. Greenhouse gases have been different sources, but main factors are fossil fuels, industrial processes, deforestation and agriculture. What is now more than ever before should be considered according to the role of forests and rangelands in atmospheric carbon sequestration? Carbon sequestration is to changes in atmospheric ca...
Bacterial whole-cell bioreporters are practical and reliable analytical tools to assess the toxicity and bioavailability of environmental contaminants, yet evidence has shown that their performance could be affected by different carbon sources. This paper evaluated the influence of carbon sources on the recA gene (ACIAD1385) in a DNA damage-inducible recA::luxCDABE Acinetobacter bioreporter and...
In the present study, the authors investigated the influence of carbon and lipid sources on regional differences in liver trace element (As, Cd, Cu, total Hg, Mn, Pb, Rb, Se, and Zn) concentrations measured in polar bears (Ursus maritimus) (n = 121) from 10 Alaskan, Canadian Arctic, and East Greenland subpopulations. Carbon and lipid sources were assessed using δ(13) C in muscle tissue and fatt...
Microorganims of the bovine rumen fluid biocatalyzed the reduction of nitro-compound substrates to yield the respective amines. This enzymatic process, using ruminal contents, has rarely been reported in association with the bioreduction of nitro groups. The biotransformation reactions catalyzed by this system were dependent of both the electronic characteristics and the area/volume of the nitr...
