Journal ArticleDOI
NAD(P)H-dependent chromium (VI) reductase of Pseudomonas ambigua G-1: a Cr(V) intermediate is formed during the reduction of Cr(VI) to Cr(III).
TL;DR: Findings show that the Cr( VI) reductase reduced Cr(VI) to Cr(III) with at least two reaction steps via Cr(V) as an intermediate.
Journal ArticleDOI
Enzymatic Reduction of Hexavalent Chromium by Hexavalent Chromium Tolerant Pseudomonas ambigua G-1
TL;DR: When hexavalent chromium (Cr6+) tolerant Pseudomonas ambigua G-l was cultivated in nutrient broth containing 150 ppm Cr6 +, the Cr6+ content of the broth rapidly decreased and Glucose protected the Cr 6+ reducing enzyme against inac-tivation on dialysis.
Journal ArticleDOI
Production of xylitol from D-xylose by Candida tropicalis: optimization of production rate.

TL;DR: The effect of culture conditions on xylitol production rate was investigated using Candida tropicalis IFO 0618 and it was found that initial yeast extract concentration was highly significant (99%), while the interaction between D‐xylose concentration and aeration rate was significant (95%).
Journal ArticleDOI
Degradation of p-Aminoazobenzene byBacillus subtilis
TL;DR: P-Aminoazobenzene (PAAB) was degradated by Bacillus subtilis and both aniline and p-phenylenediamine as degradative compounds from PAAB were identified by thin layer chromatographic-, and high performance liquid Chromatographic-methods.
Journal ArticleDOI
Purification, characterization and structure analysis of NADPH-dependent d-xylose reductases from Candida tropicalis
TL;DR: NADPH-dependent d -xylose reductases from Candida tropicalis IFO 0618 were purified and characterized and revealed three XR isomers, which showed that both XR1 and XR2 were dimers composed of identical subunits.
