At a three-leaf stage, two Fe treatments [0 mg kg-1 (Fe-) and 20 mg.kg-1 (Fe+) in the form of FeCl3] were used soil pot then concentrations α-ketoglutaric acid L-1 (A-) 50 (A+)] sprayed to rice plants Meixiangzhan Yuxiangyouzhan cultivars. We showed that seedlings exhibited an increased length fresh dry mass shoots roots with Fe+A- Fe-A+, as well content greatly. Both morphological charac...

Bacteriol. 84:778-783. 1962.-Evidence is presented to show the operation of the tricarboxylic acid cycle in Candida albicans, by studies with whole cells, cell-free preparations, and by the demonstration of most of th...

Alpha-ketoglutaric acid (KG) and hydroxymethylfurfural (HMF) are currently being investigated in clinical trials as an approach in targeted cancer therapy. Hence, a method for the simultaneous determination of KG and HMF in plasma has been developed. Due to the strongly discriminative chemical properties of KG and HMF, SPE purification is performed using an ion-exchange cartridge to separate KG...

Liver tissue of the rat, fixed in glutaraldehyde and formaldehyde, was incubated in a medium which consisted of 20 mML-aspartic acid, 2 mM alpha-ketoglutaric acid, 50 mM imidazole and 6 mM lead nitrate at pH 7.2-7.4. The electron-opaque precipitates, due to glutamic oxalacetic transaminase activity in liver cells, were found to be localized to the cristae and surface membranes of the mitochondr...

A bacterial strain of marine origin showing production of poly(g-glutamic acid) (PGA) has been identified by taxonomical and 16S rRNA studies as Bacillus subtilis. A sequential optimization approach was applied for improving the PGA production. The effect of carbon sources, nitrogen sources and pH on the production of PGA was investigated by one factor-at-a-time method. Plackett-Burman design w...

D-galacturonic acid is the main component of pectin. It could be used to produce affordable renewable fuels, chemicals and materials through biotechnical conversion. Keto-deoxy-D-galactarate (KDG) dehydratase is an enzyme in the oxidative pathway of D-galacturonic acid in Agrobacterium tumefaciens (At). It converts 3-deoxy-2-keto-L-threo-hexarate to α-ketoglutaric semialdehyde. At KDG dehydrata...
