A new technology of transforming ferulic acid, which was from waste residue of rice bran oil, into vanillin was developed by a combination of fungal strains Aspergillus niger CGMCC0774 and Pycnoporus cinnabarinus CGMCC1115. Various concentrations of ferulic acid were compared, and the highest yield reached 2.2 g l(-1) of vanillic acid by A. niger CGMCC0774(More)
The monosacchride composition of polysacchrides in Dendrobium officinal of different germplasms, physiological ages and closely related species were determined by pre-column derivatization HPLC. The results showed that the absolute and relative volumes of all monosacchrides were significantly different between D. officinale and its closely related species,(More)
Based on the theory of coal-bed methane(CBM) geology, the micro-seeps of hydrocarbon cause geochemical alterations in rocks and soil. In this study, the hyperspectral instrument, Hyperion, was used to detect the alterations and hydrocarbons on the land surface of CBM reservoirs. Our study area is in the Qinshui Basin, China. Utilizing Hyperion datasets, the(More)
Abundant field experiments have showed that the super low frequency (SLF) electromagnetic detector is sensitive to Coalbed Methane. The signal curves collected by the SLF electromagnetic detector show high amplitude anomalies in the Coalbed Methane enrichment areas. Based on this finding, we choose the Qinshui basin as study area, and take advantage of the(More)
Sucralose is a non-nutritive artificial sweetener used in a broad range of foods and beverages. In the present study, Bacillus amyloliquefaciens WZS01 was isolated, identified, and used as a catalyst both in regioselective acylation and deacetylation for sucralose preparation. Bacterial cells were immobilized on polyurethane foam and utilized to synthesize(More)
The goal of this paper is to develop and analyze the natural source Super-Low Frequency (SLF) remote sensing using the BD-6 detector and its data processing and interpretation system to help with Coal-bed Methane (CBM) reservoir information extraction. We delineated the diagram of the SLF remote sensing technique, and especially illustrated the integrated(More)
