Braunstein and Kritzmann (1) have reported that with pigeon breast muscle any a-amino acid, with the possible exception of glycine, is active in transamination with either a-ketoglutaric or oxaloacetic acid. On the other hand, the author (2) found that transamination in pigeon breast muscle is limited to the following reactions. a (1) Z(+)-Glutamic acid + oxaloacetic acid e a-ketoglutaric acid ...
A resting cell system was developed for bacteriocin Lac-B23 production from Lactobacillus paracasei J23. The resting cell medium contained (g/L): Glucose 20, Sodium acetate 5.0, MnSO4 0.25 MgSO4 0.5, Ammoniumhydrogencitrate 1.0, KH2PO4 1.0. The resting cell incubation time and temperature were 20 h and 37 °C and the effects of exogenous factors, including amino acids, glycerol, pyruvic acid, an...
Petuely's selective medium for Bifidobacterium was improved by addition of riboflavin, nucleic acid bases, pyruvic acid, and nalidixic acid. The modified medium, when examined under strictly anaerobic conditions for efficient isolation of Bifidobacterium from human fecal samples, exhibited selective and high viable counts that were close to those found on the usual nonselective medium.
completely converted oxaloacetic acid into pyruvic acid. In contrast, extraction of the plants with 2N-NaOH immediately inactivated the decarboxylase and stabilized the oxo acid levels, so that oxaloacetic acid could be reliably estimated. Although our plant extraction procedure involved slightly acid pH values this could not explain the apparent absence of oxaloacetic acid, since extractions u...

Gastric cardia cancer (GCC), which occurs at the gastric-esophageal boundary, is one of the most malignant tumors. Despite its high mortality and morbidity, the molecular mechanism of initiation and progression of this disease is largely unknown. In this study, using proteomics and metabolomics approaches, we found that the level of several enzymes and their related metabolic intermediates invo...
