柠檬酸

The regularity between taxanes content and sodium citrate concentration is not clear, but the effect of sodium citrate on taxanes production is analogy.

紫杉烷的含量与柠檬酸钠的浓度之间没有明显的规律，但柠檬酸钠对这几种紫杉烷的生产的影响具有相似性。

Taking sodium citrate or potassium citrate may be helpful in easing some of the symptoms.These are available from your pharmacist without a prescription.

以柠檬酸钠或柠檬酸钾，可能有助于纾缓部分的症状，这些都是可从您的药剂师，无需处方。

Citric acid can reduce the Cr(superscript 6+) in sodium dichromate into Cr(superscript 3+) and react with to yield citric acid chromium chelate at 75℃.

在75℃下用柠檬酸将重铬酸钠中的Cr(上标 6+)还原为Cr(上标 3+)，同时与Cr(上标 3+)发生螯合反应，生成柠檬酸铬螯合物。

According to analysis of root exudates by HPLC, aluminum induced roots of stylo to secret citrate and its secretion increased with Al concentration treated (0, 10, 20, 50 umol L-1) and the period of exposure to Al (6, 12, 18, 24 h), which indicated that Al-induced secretion of citrate is an important mechanism for stylo to resist the toxicity of aluminum.

采用高效液相色谱法对根系分泌物的分析发现，铝诱导柱花草根系分泌柠檬酸，并且其分泌量随铝处理浓度0、10、20、50 μmol L~(-1和时间(6、12、18、24 h)的增加而增加，表明铝诱导根系分泌柠檬酸是柱花草抵御铝毒害的重要机制。

However, only about one-third of the soluble calcium and magnesium is ionized, the remainder is bound to citrate, phosphate and bicarbonate in a number of complex undissociated ions, e.g.

然而实际上只有13的钙和镁以离子形式存在，蓁的全为部以复杂离子的形式与柠檬酸盐、磷酸盐和重碳酸协结合，如Ca柠檬酸盐离子

The citric acid-producing strain Aspergillus niger 2363-2, was isolated and used in our research. The fermentation conditions were optimized as follows: sucrose as carbon source 8. 0-14. 0%, ammonium chloride as nitrogen source 3. 0-4. 0g/l, initial pH 2. 0, and cultural temperature 30℃. The influential factors of formation of spores were also studied, and a series of measures were taken to restrain the spore formation on the basis of our experimental results. With the consideration of the cultural environment and microbial cell itself, the factors affecting the duration of citric acid-producing activity of microbial cells were examined, and it is found that undissociated citric acid and the ageing of microbial cells are the main factors. The experimental results also show that partial replacement of fermentation broth can lengthen the duration of citric acid -producing acitivity of microbial cells.

筛选出了用于试验研究的柠檬酸发酵用菌Aspergillus niger 2363-2，确定了其最适发酵条件—碳源选用蔗糖，浓度8.0~14.0%，氮源为NH〓Cl，浓度3.0~4.0g/l，发酵初始pH值为2.0，培养温度30℃；讨论了分生孢子产生的影响因素，并通过试验提出了抑制分生孢子产生的措施；从分析微生物所处的环境和微生物本身两个方面出发，探讨了影响微生物菌体产酸活性持久性的因素，认为分子态柠檬酸和菌体本身的老化是影响微生物产酸活性持久性的两个主要因素，并提出采用部分置换发酵液发酵能延长微生物菌体的产酸活性。

The Surface composition of grafted PET fiber was characterized by ATR-FTIR. THE results showed that there were no obvious differences between ungrafted and graft PET fiber in the spectra ,except that the typical peak of-OH in 3100cm~(-1) appeared in both Citric acid treated PET fiber and Acrylic acid treated PET fiber indicated citric acid and acrylic acid had been successfully grafted on the surface of PET fiber.

对样品的接枝效果进行红外光谱表征，发现无论是经过丙烯酸接枝处理，还是柠檬酸接枝处理，处理前后纤维的红外吸收光谱图都没有明显的区别，说明接枝前后纤维的主体性质没变，但是，二者在3100cm~(-1)处都出现了羟基的特征吸收峰，说明柠檬酸和丙烯酸都已经接枝上了PET纤维表面。

When AlCA reacts with HPAM, the lower the pH value of AlCA, the faster the rate of gelling reaction. At a certain pH value, the smaller the ratio of /, the slower the rate of the gelling reaction.

结果表明，柠檬酸铝在碱性条件下的稳定性、热稳定性及室温下的放置稳定性均随／的减小而提高，pH值过高或过低的柠檬酸铝均不能长期稳定存在。
