Influence of the nitrogen source on Saccharomyces cerevisiae anaerobic growth and product formation.
To prevent the loss of raw material in ethanol production by anaerobic yeast cultures, glycerol formation has to be reduced. In theory, this may be done by providing the yeast with amino acids, since the de novo cell synthesis of amino acids from glucose and ammonia gives rise to a surplus of NADH, which has to be reoxidized by the formation of glycerol. An industrial strain of Saccharomyces ce...
Abstract Goats raised for meat production are often transported long distances. Twelve-month-old male Spanish goats were used to determine the effects of habituation trailers on plasma metabolomic profiles when periods. In a split-plot design, 168 separated into two treatment (TRT; whole plot) groups and maintained different paddocks. Concentrate supplement was fed one group inside livestock (h...
The importance of homoserine in the metabolism of amino acids in a variety of living forms is now well established. This amino acid was found to be the common precursor of methionine and threonine in Neurospora crassa (1). Enzymes involved in the conversion of aspartic acid to threonine via homoserine have been studied in Escherichia coli (2-5) and in bakers’ yeast (6-S). The presence of homose...
Abstract Purpose In this work, pH-sensitive alpha-ketoglutaric acid-modified Fe/Mg-carbonate apatite (α-KAM-Fe/Mg-CA) NPs were introduced and found to be capable of promoting the selective delivery cancer-killing drug doxorubicin (DOX) in breast cancer cells, while simultaneously mitigating DOX toxicity on normal cells. Methods As part characterization evaluation α-KAM-Fe/Mg-CA target a series ...
BACKGROUND The objective of this study was to identify molecular alterations in the human blood serum related to bipolar disorder, using nuclear magnetic resonance (NMR) spectroscopy and chemometrics. METHODS Metabolomic profiling, employing 1H-NMR, 1H-NMR T2-edited, and 2D-NMR spectroscopy and chemometrics of human blood serum samples from patients with bipolar disorder (n = 26) compared wit...
During ail examination of microbial culture filtrates capable of reversing the inhibition of Streptomyces aureofaciens Strain NRRL B-1286 caused by the metliionine analogue norleucine, one filtrate was found to possess striking reversing potency. Analysis showed this could not be due to methionine. The reversal properties of the filtrate were traced to glutamic acid which imparted high reversin...
