摘要:
The present invention is related to a direct solid sample analytical technology for determining a content and a uniformity thereof in a lyophilized kit of a sulfur-containing chelator with a stable complex capacity for radiotechnetium (Tc-99m) and radiorhenium (Re-186, Re-188). An economical, stable and easily accessible coal standard is used herein as a contrast substance to construct a sulfur calibration curve, followed by obtaining the sulfur content and the uniformity thereof in the solid lyophilized sample by interpolating the foregoing result into the sulfur calibration curve. Then, the weight content percent is converted to get the content and the uniformity of the chelator in the lyophilized kit. The quality control of active pharmaceutical ingredients (API) in the lyophilized kit during key production processes and clinical applications is thus assured.

摘要:
Disclosed is a method for increasing the concentration of xylose in lignocellulosic hydrolysate. The method includes the step of extruding lignocellulosic material and mixing the lignocellulosic material with diluted acid and the step of conducting hot-water extraction on the mixture. Hence, the concentration of the xylose in the lignocellulosic hydrolysate can achieve a high concentration of 60 g/L, and the yield of the xylose can reach to 90%.
摘要:
A hydrolysate-adapted yeast, Pichia stipitis INER 1128, is cultivated according to the present invention. The adapted yeast can effectively convert xylose into ethanol in lignocellulosic hydrolysate, which is not even detoxified. Well ethanol yield is obtained while xylose is not wasted and thus cost is reduced.

Algae are irradiated to obtain a hormesis so that its thickness is increased or its growth time is shortened. A cubic rack with an adhesion unit is used so that more algae are planted to be cultured on the adhesion unit through the irradiation for mass production.
