Heterologous expression of a novel psychrophilic Cu/Zn superoxide dismutase from Deschampsia antarctica
(Elsevier, 2009-09)"Superoxide dismutase (SOD) catalyzes the conversion of the superoxide radical (O2−) into oxygen and hydrogen peroxide. Deschampsia antarctica is a plant that grows in Antarctica and survives to extreme low temperature and ... -
Indole modifies the central carbon flux in the anaerobic metabolism of Escherichia coli: application to the production of hydrogen and other metabolites
(Elsevier, 2016-12)"Indole is a bicyclic signaling molecule with effects on both eukaryotic and prokaryotic cells. The majority of studies of indole action have been performed with bacteria cultured under aerobic conditions and little ... -
Nitrogen sources impact hydrogen production by Escherichia coli using cheese whey as substrate
(Elsevier, 2013-09)"The impact of nitrogen source on hydrogen production by Escherichia coli WDHL (Delta hycA Delta lacI) strain using cheese whey as a substrate was evaluated. To improve the assimilation of complex proteins such as lactalbumin, ... -
Novel fusion protein derived from vasostatin 30 and vasoinhibin II-14.1 potently inhibits coronary endothelial cell proliferation
(2013-07)"Angiogenesis has been considered an important target for cancer therapy. The inhibition of angiogenesis represents a promising strategy for anti-cancer treatment, tumor growth inhibition, and metastasis. Vasostatin 30 ... -
Identification of calcium stress induced genes in amaranth leaves through suppression subtractive hybridization
(Elsevier, 2011-11)"Calcium (Ca2+) is a critical ion for the growth and development of plants and plays an important role in signal transduction pathways in response to biotic and abiotic stresses. We investigated the Ca2+ stress responsive-genes ... -
Identification of yeast and bacteria involved in the mezcal fermentation of Agave salmiana
(Wiley, 2008-06)"Aims: To identify the yeast and bacteria present in the mezcal fermentation from Agave salmiana. Methods and Results: The restriction and sequence analysis of the amplified region, between 18S and 28S rDNA and 16S rDNA ... -
Biohydrogen production by the psychrophilic G088 strain using single carbohydrates as substrate
(Elsevier, 2016-05)"The production of biohydrogen by psychrophilic G088 strain ([EU636029]), closely related to Polaromonas rhizosphaerae ([EF127651]) was evaluated using xylose, glucose, fructose, galactose, lactose or sucrose as a carbon ... -
Hydrogen production by Escherichia coli ΔhycA ΔlacI using cheese whey as substrate
(Elsevier, 2010-01)"This study reports a fermentative hydrogen production by Escherichia coli using cheese whey as substrate. To improve the biohydrogen production, an E. coli ΔhycA ΔlacI strain (WDHL) was constructed. The absence of hycA ... -
Estimation of hydrogen production in genetically modified E. coli fermentations using an artificial neural network
(Elsevier, 2010-12)"Biological hydrogen production is an active research area due to the importance of this gas as an energy carrier and the advantages of using biological systems to produce it. A cheap and practical on-line hydrogen ... -
