不发酵的

The results showed that the Mulberry fruit surface carried large numbers of yeast but little other mixed fungi; ethanol fermentation reached the peak value in 48h'; before vinegar production the acetification bed breeding took 9~10d, but the vinegar fermentation cycle was only about 24h during production .

结果表明，桑椹果实表面携带有大量的酵母菌而几乎不带其他杂菌，酒精发酵醪除含有大量的酵母菌之外未发现有其他杂菌，酒精度在发酵 48h 时达到高峰；桑椹醋生产前的醋酸菌床培育需要9～10d 时间，投入生产后醋酸发酵周期仅需要24h ；桑椹醋总黄酮含量高达6.68 mg/mL ，对 DPPH 自由基的清除作用远高于山西陈醋、镇江香醋和山楂果醋，具有良好的抗氧化作用；利用桑椹醋自身色素颜色变化可判断酸度测定时酸碱滴定终点。

More metabolites could be detected when the TLC was carried out in system II (chloroform∶methanol=9∶1) and system III (butanol∶acetic acid∶water=4∶1∶5) with anisaldehyde test solution.

对每一株菌而言，产生最多产物的发酵培养基各不相同，为了获得尽可能多的次生代谢产物，不同菌株选用的发酵培养基不一样。

Phosphate. It is essential glutamic acid fermentation process, but the concentration can not be too high, otherwise they will be to valine fermentation.

磷酸盐。它是谷氨酸发酵过程中必需的，但浓度不能过高，否则会转向缬氨酸发酵。

Results showed that all the three sweet sorghum varieties contained plentiful sugar, which can provide enough carbon source for alcohol fermentation, however, total nitrogen and some mineral elements（Fe3＋）cannot meet the needs of alcohol fermentation. Activity of most microbes in stalk juice can be inhibited and the sugar can be maintained when the stalk juice was condensed to 4～5 times. Due to the reasons that the activity of acetous microbe or hydrolysis enzyme inside stalk juice can be maintained, ratio of reducing sugar to total sugar was increased with storage time at 55～60℃,0.15 MPa vacuum condensed condition, which can be beneficial for the purpose of alcohol fermentation.

结果表明，三个品种都含有丰富的糖分，可以为酵母菌发酵制取酒精提供良好的碳源，但总氮和某些矿物质元素（如：Fe3＋）不能满足酒精酵母的营养需要；甜高粱茎秆汁浓缩至4～5倍时，可以抑制汁液中大多数微生物的活动，使其中糖分不受损失；在试验设定的真空浓缩工艺条件下（55～60℃，0.15 MPa）甜高粱茎秆汁中产酸微生物或水解酶类仍保持活性，使得还原糖占总糖的比率随贮藏时间延长而升高，这有利于酒精发酵。

Secondary fermenters:key organisms in the conversion of complex organic materials to methane (espacially the H2-producing fatty acid-oxidizing bacteria).23、List two syntrophic microorganisms and describe a bit.

乙醇发酵菌发酵乙醇产生H2和乙酸，产甲烷菌消耗利用乙醇酵解菌产生的H2，总反应为产能反应，产甲烷菌不能直接利用乙醇。

However,the regulation of mtlR is not the immediate cause of the ferment difference of the toxigenic and non-toxigenic strains.

但是mtlR还不是引起快慢发酵菌株对甘露醇发酵差异的直接原因。

To study the technology used for brewing bifidobeer fermented by Bifidobacterium bifidum and Saccharomyces cerevisiae,Australia malt is sprinkled and milled.Wort is prepared by lixiviated saccharification,filtered,hops added,boiled and co-fermented by Bifidobacterium bifutum and Saccharomyces cerevisiae,and followed by antisepsis and centrifugation.

采用增湿法粉碎澳大利亚麦芽，麦皮破而不碎，麦粉较细，干法粉碎大米成细粉；选用双醪浸出糖化法进行麦汁制备、过滤、添加酒花和麦汁煮沸，麦汁呈黄色、澄清，可发酵糖和α-氨基氮的含量符合发酵要求；利用双歧杆菌和酿酒酵母共同发酵啤酒，消毒灭菌和低温离心后进行灌装；通过几项重要指标的检测，进行评判啤酒的质量和性能。

If a malo-lactic fermentation is desired, the wine remains on the lees without sulfating until the mali-lactic fermentation has taken place.

如果需要进行苹果酸-乳酸发酵，沉淀物上的酒体不需要硫化处理，直到完成苹果酸-乳酸发酵。

The yeast treated by ultrasonic wave hardly affect the ferm...

超声波处理的酵母菌对发酵进程影响不大，均能正常发酵，对发酵后的酒样影响较大，经方差分析发现：酒度间存在显著性差异，超声波处理的酒度大部分降低，个别升高；残糖含量差异极显著，经超声波处理样品残糖含量均比对照高；各样品的总酸和挥发酸含量差异显著；超声波对总酚含量的影响不明显，对蛋白含量影响较大。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
