Ultrasound effects on the acetylation of dioscorea starch isolated from Dioscorea zingiberensis C.H. Wright

Chemical Engineering and Processing: Process Intensification, 2012
The objective of current work is to investigate the intensification of starch towards acetylation by acetic anhydride after ultrasound treatment. Native dioscorea starch (NDS) slurry was ultrasonically treated to produce ultrasound-treated dioscorea starch (UTDS).

Pathways and kinetics analysis of biotransformation of Dioscorea zingiberensis by Aspergillus oryzae

Biochemical Engineering Journal, 2010
Abstract In this paper, the pathways and kinetics for the production of diosgenin via biotransformation of Dioscorea zingiberensis C.H. Wright by Aspergillus oryzae CICC 2436 were analyzed. After 120 h of biotransformation at 30 °C, the concentration of diosgenin in the culture reached 36.87 ± 1.27 μmol/g raw herb, which was 21.2 times its initial ...

Study on anoxic-oxic process treating for dioscorea zingiberensis wastewater

2011 International Symposium on Water Resource and Environmental Protection, 2011
The purpose of this paper was to investigate the characteristics of anoxic-oxic (A/O) process treating for dioscorea zingiberensis wastewater. Calcium oxide was added into the wastewater to adjust the pH value in the pretreatment, the 0.45g/L calcium oxide concentration was chosen as the optimum concentration.

Screening a Novel High Effective Dioscorea Zingiberensis Degradation Strain

2011 International Symposium on Water Resource and Environmental Protection, 2011
12 strains of cellulolytic microorganism were isolated from the AB reactor of dioscorea zingiberensis wastewater treatment. A bacterial strain was obtained through the screening experiments of decomposition of dioscorea zingiberensis, which had high degradability for dioscorea zingiberensis and was named D-1.

[Isolation and structure determination of steroidal saponin from Dioscorea zingiberensis].

Yao xue xue bao = Acta pharmaceutica Sinica, 2010
To study the chemical constituents of Dioscorea zingiberensis Wright, the EtOH extract of fresh rhizomes of D. zingiberensis was concentrated and partitioned further to produce petroleum ether-, ethylacetate-, n-butanol- and water-soluble fractions. The water-soluble fraction was subjected to column chromatography on macro resin AB-8, and the final ...

Transcriptome Analysis of Dioscorea zingiberensis Identifies Genes Involved in Diosgenin Biosynthesis

Genes and Genomics, 2017
Dioscorea zingiberensis is the main plant source of diosgenin, a precursor for the production of steroid hormones used in the pharmaceutical industry. The extraction process of diosgenin from D. zingiberensis can generate high-acid and high-strength wastewater on a large scale and can threaten the environment.

Functional characterization of squalene epoxidase and NADPH-cytochrome P450 reductase in Dioscorea zingiberensis

Biochemical and Biophysical Research Communications, 2019
Dioscorea zingiberensis is a perennial medicinal herb rich in a variety of pharmaceutical steroidal saponins. Squalene epoxidase (SE) is the key enzyme in the biosynthesis pathways of triterpenoids and sterols, and catalyzes the epoxidation of squalene in coordination with NADPH-cytochrome P450 reductase (CPR).
