The organic acids composition of six wild edible mushroom species (Amanita caesarea, Boletus edulis, Gyroporus castaneus, Lactarius deliciosus, Suillus collinitus, and Xerocomus chrysenteron) was determined by an HPLC-UV detector method. The results showed that all of the samples presented a profile composed of at least five organic acids: citric, ketoglutaric, malic, succinic, and fumaric acid...

KODAMA, H., OKADA, S., INUI, K., YUTAKA, T. and YABUUCHI, H. Studies on ƒ¿-Ketoglutaric Aciduria in Type I Glycogenosis. Tohoku J. exp. Med., 1980, 131 (4), 347-353 Urinary excretion of the organic acids in patients with type I and III glycogenosis was investigated. In all patients with type I glycogenosis, urinary ƒ¿-ketoglutarate concentration was about 10 times the normal value. ƒ¿Ketoglutar...

Many methods are to be found in the literature for the determination of several of the individual acids of the “citric acid cycle;” however, to date no method has been available for the simultaneous determination of all of the acids in a single sample of tissue. Isherwood (1) employed partition chromatography on silica gel to separate and determine subsequently a group of acids present in fruit...

The study of the metabolism of cells by a method termed inhibition analysis (l-3) led to the initial proposal that the antibacterial index (4) is a function of the inhibited enzyme system which becomes the limiting factor for growth of the organism. It was further proposed that if the product of this enzyme system is supplied to the organism the analogue either becomes ineffective as a growth i...

Two putative malate dehydrogenase genes, MJ1425 and MJ0490, from Methanococcus jannaschii and one from Methanothermus fervidus were cloned and overexpressed in Escherichia coli, and their gene products were tested for the ability to catalyze pyridine nucleotide-dependent oxidation and reduction reactions of the following alpha-hydroxy-alpha-keto acid pairs: (S)-sulfolactic acid and sulfopyruvic...

The study of serum transaminases has recently entered clinical practice. In December, 1954, Wroblewsky and La Due demonstrated an increase of glutamic-oxalacetic (GOT) transaminase in the serum of patients suffering from various liver diseases and in carbon tetrachloride intoxication. In 1955, de Ritis, Coltorti and Giusti demonstrated an increase of both aspartic-ketoglutaric (GOT) and alanine...

Bacteriol. 84:784-792. 1962-Oxidative assimilation of glucose by washed-cell suspensions of Pseudomonas aeruginosa was studied using C(14)-labeled substrate. At the time of glucose disappearance, only small amounts o...
