The results showed that the Saccharopolyspora spinosa SP06081 protoplast yield was the highest under these conditions: the collected mycelium from SP06081 grown in Tryptic Soy Broth medium with 0.2% glycin for 48 h was treated by 0.1 mg/mL lysozyme at 28oC for 20 min, then plated on the R2YE medium with sucrose as osmotic stabilizer, the number of regeneration protoplast was up to 108/mL. The protoplast-regenerated strains exhibited changes in morphology and antibiotic production, 29.3% protoplast-regenerated strains was characterized by loose mycelium and abundant broken branches as did their parent. Among them, 58.2% strains presented the trend to positive variation in spinosad yield, with the highest spinosad yield of up to 582.0 mg/L, 85.6% higher than that of their parent.

香料烟化学成分一个引人注目的特征是含有较多的低级脂肪酸，其中异戊酸和β—甲基戊酸的含量是烤烟的几百倍以上。

The addition of puerarin, tea polyphenol and acid compositions in VECO effectively improved the effects on soberness, intoxication avoiding, ataxia correcting and memory barrier eliminating. The tea polyphenol has superior behavior on soberness, intoxication avoiding and memory barrier eliminating than that of puerarin, while puerarin is more effective in the function of ataxia correcting than tea polyphenol.

金葛露中加入葛根素、茶多酚和酸类物质有助于解酒、防醉、纠正运动失调和改善记忆障碍，其中茶多酚的解酒、防醉和改善记忆障碍的效果比葛根素明显，葛根素纠正运动失调作用的效果比茶多酚明显。

Various chrome complex dyes(1:1 ratio) of mordant black 1,mordant black 7,mordant black 9 and mordant black 11 have been synthesized and sodium dichromate is been used as mordant agents instead of Cr3+ to oxidate dyes sufficiently.

The thermolysis electrocyclic reaction was affected significantly by the structuresof substrates, reaction temperature and time as well as Lewis acids and organic acids.

通过对反应物的结构、反应温度、反应时间、Lewis酸和质子酸的催化效果等诸多因素对该反应的影响进行探讨发现，在反应中使用1.1当量的三氟乙酸时，不仅反应时间可以缩短8-21小时，产率也可以提高20-30％。

Proline was much more accumulated in the fleshy leaves of K.foliatum with increased salt concentration concided with the expression pattern of K.foliatum P5CS, suggesting that proline and betain as two effective osmolytes had important functions for Kalidium foliatum during stress.

检测的各基因均受盐的诱导。P5CS和KfBADH基因的表达随着盐浓度的升高而表达逐渐增强，而脯氨酸的含量也随着盐胁迫程度的增强而在盐爪爪肉质化叶内积累更多，说明脯氨酸和甜菜碱作为重要的渗调物质，在植物逆境胁迫中可能发挥着重要的作用。

The tail group of cysteamine containing amine moiety can easily protonize in acidic conditions. Heterpolyanions was successfully immobilized on such a positive-charged surface. By using quartinized conducting polymer containing osimium-bipyridine complexes, a sandwiching multilayers has been fabricated.

利用氨端基自组装膜在酸性条件下荷正电的特点，成功地将荷负电的杂多酸分子固定于其上，并在此基础上，通过荷正电的季胺化聚合物组装了多层的杂多酸修饰电极。

Densities of glycine in glucose-water and sucrose-water mixed solvents have been measured to 298.15 K by an oscillating-tube densimeter. Apparent molar volumes, limiting partial molar volumes and number of hydration of glycine have been calculated. The transfer volumes from water to sugar-water mixtures have been obtained and discussed in terms of the structural hydration interaction model.
