The effects of wheat cellulose nanoparticles on pasting and texture properties of pea starch were investigated. By analysis of RVA data,when wheat cellulose nanoparticles addition dosage was increased from 0%to 20%,there were few changes for pasting temperature of pea starch,while peak viscosity,trough viscosity,final viscosity,breakdown and setback increased. By analysis of TPA data, the springiness of gel did not change much when adding wheat cellulose nanoparticles. When wheat cellulose nanoparticles addition dosage was 5%,the hardness of pea starch decreased;while the wheat cellulose nanoparticles addition dosage was 10%to 20%,the hardness of pea starch increased and the biggest hardness of pea starch was 927.29 g.

目的：研究小麦纤维素(非比麸)用于治疗妊娠期便秘的疗效和安全性.方法：采用前瞻性自身对照研究的方法，对72例妊娠期便秘的患者给予小麦纤维素治疗2周，观察服药前后便秘症状及大便性状情况，并予评分量化比较.结果：小麦纤维素治疗后排便次数明显增加，大便性状得到改善，治疗总有效率86.11%，用药前后对比有效率差异有统计学意义(P<0.01).服药期间未发现腹胀、腹痛、腹泻等明显不良反应.结论：小麦纤维素治疗妊娠期便秘疗效确切，安全.

Objective:To study the efficacy and safety of Fiberform on the treatment of pregnancy constipation. Methods:Prospective self-controlled clinical trial using Fiberform was conducted for 2 weeks in 72 cases of patients with pregnancy constipation. Symptoms and the character of feces before and after the treatment were observed and evaluated according to a score scheme. Results:Frequency of defecation increased significantly,and the character of the feces was improved after the treatment. The total efficacy rate was 86.11%. No adverse event such as abdominal distention ,pain or diarrhea was observed during the administration of the treatment. Conclusions:Fiberform is effective and safe in the treatment of pregnancy constipation.

小麦蛋白复合纤维是利用小麦麸皮制备的一种新型功能性再生纤维素纤维。文中对小麦蛋白复合纤维的物理性能和可染性进行了研究。结果表明，小麦蛋白复合纤维断裂强度与黏胶纤维、竹浆纤维相近，回潮率较高，氨基酸含量达144．8mg／g；该纤维具有优良的可染性，采用棉用活性染料进行染色，固色率高，色泽艳丽，牢度良好，其深浓色产品不适合使用毛用活性染料和酸性染料染色，也可以用直接染料染色．但耐水洗牢度欠佳。

The wheat gluten composition fiber made of wheat bran is a kind of new functional regenerated cellulose fiber. This paper studies physical properties and dyeability of wheat gluten composition fiber. The results show that breaking strength of wheat gluten composition fiber is similar to those of viscose fiber and bamboo pulp fiber. The moisture regain is high and amino acid content is 144.8 mg/g. The fiber has excellent dyeability. The fiber uses cotton reactive dyes with high fixation rate, bright colors and good fastness. Its deep color products are not suitable for using wool reactive dyes and acid dyes. It can use direct dyes, but the washing fastness is not good enough.

目前生物柴油的价格是石化柴油的1.5倍,寻求新的廉价易得的原料降低生物柴油的成本是必然趋势。作物秸秆是一种低廉普遍的废弃物,秸秆中含有纤维素,半纤维素等成分,水解成单糖后可以作为合成生物柴油所需的糖类来源。利用前期研究构建的基因工程菌Escherichia coli pET28a(+)-PAW发酵秸秆(玉米秸秆和小麦秸秆)水解液得到乙醇,并在胞内将乙醇与外源添加的脂肪酸进行同步转化合成生物柴油的主要成分脂肪酸乙酯。HPLC分析表明玉米水解液中葡萄糖含量(10.40 g·L-1)较高,小麦水解液中木糖含量(40.56 g·L-1)较高。E.coli pET28a(+)-PAW能够有效地以小麦和玉米两种秸秆水解液作为糖类替代物发酵生产生物柴油,小麦水解液培养基中的生物柴油含量(0.30 g·L-1)高于玉米水解液培养基中的含量(0.25g·L-1),同时也高于现有报道。结果表明,以秸秆水解液作为原料,利用基因工程菌合成生物柴油是可行的,有助于降低生物柴油的原料成本。

The price of biodiesel is approximately 1.5 times higher than that of traditional diesel .It is urgent to explore cheaply available substrates to reduce the cost of biodiesel production .As one of the cheap and widespread wastes, lignocellulose contained cellulose and hemicellulose which could be hydrolyzed and used in the fermentation of biodiesel.The genetic engineered strain Escherichia coli pET28a (+)-PAW fermented straw hydrolysates into alcohol, and further into biodiesel with fatty acids by one-step transformation in-vivo.The HPLC analysis showed that the corn straw hydrolysate had a higher glucose concentration (10.40 g?L-1 ) and the wheat straw hydrolysate had a higher xylose concentration (40.56 g?L-1 ).When straw hydrolysates were utilized as sugar substitutes for biodiesel production by E.coli pET28a(+)-PAW, the maximum biodiesel yield of 0.30 g? L-1 ( wheat hydrolysate ) was obtained which is higher than the yield of biodiesel 0.25 g?L-1 (corn hydrolysate) and the present
