In order to realize the comprehensive utilization of rape straw,the catalytic liquefaction of rape straw was performed to prepare liquid oil under the high temperature high pressure condition.The contents of cellulose,hemi-cellulose and lignin in rape straw were 25.45%,11.57%,28.73% respectively.The element analysis showed that the element content of rape straw did not change a lot before and after direct liquefaction,the high heating value(HHV) of raw rape straw and residues were respectively 10.58,10.47 MJ/kg.Sulfate catalyst was superior to chloride catalyst in catalytic liquefaction of rape straw,ferric sulfate and ferrous sulfate presented better catalytic capacity in neutral solvent,especially in ketone solvents.Appling ferric sulfate as catalyst and acetone as solvent,the conversion rate of rape straw could reach to 47.106% after 4 h of liquefaction under solid-to-liquid ratio of 1.0∶19.3 and catalyst dosage of 1%.Soaking of rape straw in 1% KOH solution for 12 h,the cellulose,hemi-cellulose and lignin in rape straw was slightly swelled,which could improve the conversion rate of liquefaction.The TG/DTG curve showed that the residue was better than rape straw in combustibility;however,its activation energy was slightly less than that of rape straw.
A 26-year-old Chinese female whose BMI was 36.33 had a history of 2 years of urinary frequency, urgency and urge incontinence without dysuria. She voided more than 20 times a day during waking hours and awoke 5 times a night to void. She noted enuresis but had no voiding difficult.
Objective:In order to get the process of fermenting high iron yeast, its culturing factor were studied in all kinds of condition. Methods:In this experiment The four different edible funguses were chosed to incubate in yeast milk to which added different iron compound concentrations, and then the biomass, yield and content of iron binging with Saccharomyces cerevisiae were observed. In this experiment the Serum concentration of iron was determined by spectrophotometer. Results:Saccharomyces cerevisiae cell that was capable of binding high iron was exactly incubated at the temperature of 28 ℃, pH for 5～7 or so, ferrisulphas added to yeast milk, stirring speed to 200 r/min, and 10 percent of contents inoculated to yeast milk for the best. Conclusions:the high iron yeast were gottenby biotech fermenting technique .
Objective: the eight health domestic rabbits were crossly administered high iron yeast and FeSO_4 orally to study its pharmacokinetics and bioavailability. Methods: In this experiment the serum concentration of iron was determined by spectrophotometer, and the data of drug-time were processed by MCPKP program. Result: The data of drug-time accorded with two and one ope n model , the main pharmacokinetic parameters of high iron yeast were: Ka=0.67 /h, Kel=0.28/h, Ka=1.08 h, T_(1/2 α)=1.82 h, T_(1/2 β) =9.73 h, T_ (max)=2.73 h, C_(max)=1.60 μg/ml, AUC=12.59 mg/ h~(-1) · l~(-1), FeSO_4 were T_(max)=2.62 h, C_(max)=1.41 μg/ml, T_(1/2Ka) =0.94 h, Kel=0.24 h~(-1),T_(1/2K) =3.05 h, Conclusions: bioavailability F (AUC ()_(high iron yeast)/ AUC()_(ferrisulphas)) % was 122%. The consequence indicated that the bioavailability of high iron yeast was 1.22 times that of ferrisulp has, and domestic rabbits absorbed the high iron yeast is better than ferrisulphas.
Jerusalem artichoke, a native plant to North America has recently been recognized as a promising biomass for bioeconomy development, with a number of advantages over conventional crops such as low input cultivation, high crop yield, wide adaptation to climatic and soil conditions and strong resistance to pests and plant diseases. A variety of bioproducts can be derived from Jerusalem artichoke, including inulin, fructose, natural fungicides, antioxidant and bioethanol. This paper provides an overview of the cultivation of Jerusalem artichoke, derivation of bioproducts and applicable production technologies, with an expectation to draw more attention on this valuable crop for its applications as biofuel, functional food and bioactive ingredient sources.
The present study aimed to evaluate the effects of fermentation products of Cordyceps militaris (FPCM) on growth performance and tibia mineralization of broiler chicks. A total of 240 one-day-old female Ross 308 broilers were allotted into four treatments with six cages of 10 chicks each. Four diets were the control diet supplemented with 0, 1, 2 and 4 g/kg of FPCM, respectively. Compared with the control, supplementation of 1 g/kg FPCM improved body weight gain of broilers from 22 to 42 days of age and from 1 to 42 days of age (P < 0.05); 4 g/kg of FPCM enhanced the feed intake of 22- to 42-day-old and 1- to 42-day-old chicks (P < 0.05). Addition of 2 g/kg FPCM increased tibia calcium (Ca) content of broilers at 21 and 42 days (P < 0.01). FPCM did not affect serum biochemical parameters (P > 0.05). These data indicate that FPCM had positive effects on growth performance of broiler chicks and the optimal dietary FPCM level was 1 g/kg in chicks from 1 to 42 days of age.
