合成代谢产物

Based on the mechanism of riboflavin biosynthesis and regulation, a few important intermediates in the pathway were analyzed.

本文以核黄素的生物合成和代谢调节机制为依据，分析了几种重要中间产物的流向。

The detection of metabolic intermediates of glycolysis in cell demonstrated that the concentration of FDP and ATP increased abnormally when LM was added. So, the LM had an important part in the carbon catabolite repression of γ-CGTase fermentation.

对细胞内的糖酵解中间产物进行检测后发现，1，6-二磷酸果糖和ATP的含量在添加直链麦芽低聚糖后异常增加，所以直链麦芽低聚糖在B.macorous WSH02-06合成γ-CGT酶的过程中对产酶起到分解代谢阻遏效应。

The induction of xylanase activity is dependent on inducer concentration and is not fully repressible by glucose and starch.

木糖在低浓度下具有诱导WL-11木聚糖酶生物合成的作用，但高浓度木糖则表现出一定的代谢终产物抑制效应。

Succinic acid can also be used to produce 1,4-Butanediol,Tetrahydrofuran,γ-Butyrolactone,and other chemical intermediates.

琥珀酸作为TCA循环的中间产物之一，在生物的代谢中占有非常重要的地位，因此被广泛应用于合成化学药物的中间体。

The quality of purified 2-KGA from its fermentation products was up to industrial standard. In addition, several hexoses, such as D-glucose and D-sorbitol can be utilized to synthesize 2-KGA by this newly-mixed culture. The growth and anabolism of the B529-V6 were studied in 4M〓 and 300M〓 fermentor respectively. The results showed that its growth and anabolism were affected by carbon sources, ratio of D-glucose and L-sorbose, nitrogen sources, growth factors, inoculum quality and culture condition including the initial pH value, temperature and ventilation.

新菌系B529-V6表现出了较强的高浓度L-山梨糖耐受能力、较高的底物代谢速率和较高的2-KGA转化能力，在8％山梨糖浓度的发酵培养基中培养48h，糖酸转化率较对照菌系提高了5.94％；山梨糖浓度提高至10％，其生长代谢受影响程度较小，且能不同程度地利用葡萄糖和山梨醇为底物，合成维生素C前体-2-酮基-L-古龙酸（2-KGA），其发酵产物2-KGA经反相高效液相色谱分析其质量符合工业化生产要求。

During the Normal cultivation, optical colorimetric method was used to analyze the cells' metabolites and exudates: Urea and ALB.

它能在细胞正常培养过程中，通过光学比色的方法分析培养液中细胞合成及代谢的产物－尿素和白蛋白，从而得到细胞的功能活性。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.
