苹果乳酸的

The positive effects include invert of sugar into alcohol by yeast and invert of malic acid into lactic acid by lactobacillus etc.

摘 要：在整个葡萄酒的酿造生产过程中，不同的微生物起着不同的作用，酿酒酵母将糖转化成酒精，乳酸菌会将苹果酸转化成乳酸等，这些是正常的发酵过程；而醋酸菌会使葡萄酒发生酸败，产膜酵母会使葡萄酒起膜浑浊，霉菌会影响酒的风味等，这些是有害微生物的作用。

The results indicated that resveratrol content in different producing areas varied during the fermentation and it increased gradually along with the fermentation and the addition of pectase and it reached the highest level up to chief fermentation, then it decreased and maintained a certain level till malolactic fermentation.

结果表明，尽管不同产地在发酵过程中生成的白藜芦醇含量有所不同，但都随着果胶酶添加和酵母发酵的进行，白藜芦总醇含量逐渐上升，至主发酵时白藜芦总醇含量达到最高，进入苹果酸-乳酸发酵后，白藜芦醇含量有所下降并维持一定的水平。

Kinds of organic acids (pyruvic acid, malic acid, lactic acid, acetic acid, citric acid and succinic acid) presented in beer were intensively studied in this paper.

本文以对啤酒质量有重要影响的6种有机酸(丙酮酸、苹果酸、乙酸、乳酸、柠檬酸和琥珀酸)为研究对象，确定了淡爽型啤酒的最佳有机酸组成，并研究了酿造过程中有机酸的变化及影响因素。

Promoting Prunus Humilis Bunge Industrialization to Protect Ecological Environment;2. This article is about the ratafia of Prunus humilis bunge of dry and sweet which has the special fragrance and flavor of Prunus humilis bunge .

研制开发具有欧李果独特的香气和风味的干型和甜型欧李果酒，通过对欧李果的特点研究，确定了果实中度破碎，18℃￣22℃下低温浸皮发酵，18℃￣20℃"苹果酸-乳酸发酵"，再经调配、冷冻、0。

In the last 20 years, cloning and expression of MLF related genes in Saccharomyces cerevisiae has been studied. Research progress and problems in this field are reviewed.

近20年来，围绕苹果酸-乳酸发酵相关基因的克隆以及在酿酒酵母中表达的研究取得了一些进展，本文就该研究进展和存在的问题进行了综述。

Glycerolgenesis. Organic acids was mainly produced during growth phase, acetic acid was the highest, about 1. 6g/L. When the amount of acetic acid and α-Keto glutaric acid was increased slightly and others decreased a bit in 〓 process. The kinds and amount of arganic acide during microbial glycerol production in C.

有机酸主要是菌体生长过程产生的，在酵母生长达平衡期时乙酸积累达最高值1.6g/L，乳酸、丙酮酸、酮戊二酸、苹果酸也都达较高浓度，此时相应的pH降低至最低，随着发酵进行其中乙酸和酮戊二酸略有增加，而其它有机酸是减少的。

Most sugars, organic acids, phenolic acids and most amino acids increased significantly with elevated CO_2. The treatment, 950±50μmol·mol-1 CO_2 enrichment for 6 h every day had more obvious effects than the treatment, 950±50μmol·mol-1 CO_2 enrichment for 3 h every day. Levan, sucrose, arginine, oxalic acid, alanine, malic acid, acetic acid, lactic acid cinnamic acid,ρ- hydroxybenzoic acid and benzoic acid increased significantly.

CO_2施肥黄瓜根系分泌有机酸、氨基酸、糖和酚酸的总量增加，上、下午均施肥的处理分泌数量最多；CO_2施肥显著促进了果聚糖、蔗糖、草酸、苹果酸、乙酸、乳酸、多数氨基酸、肉桂酸、对羟基苯甲酸和苯甲酸等组分的分泌；单位鲜重根系分泌糖和酚酸的数量增加，多数氨基酸保持不变或降低，但有机酸分泌规律不一致。

Malolactic fermentation is an important approach to improve the quality of grape wine.

苹果酸-乳酸发酵是葡萄酒酿造过程中改善葡萄酒品质的重要手段之一，大部分的红葡萄酒和某些特定品种的白葡萄酒都要经过MLF工艺。

The phenetic characteristics including Gram stain, catalase test, the adaptation to different stress conditions and producing acid from carbohydrates were tested.

结果表明，分离菌株N7-03具有较强的苹果酸-乳酸酶活力[117.05mg苹果酸/log]，进一步的研究表明，N7-03具有良好的酿造学适应性。2。

31DH suspend in the dry red wine and ferment,the density of the dry immobilized 31DH was changed by various materials.

通过选用不同的材料调节干固菌胶粒的比重，使固定化酒类酒球菌31DH悬浮于干红葡萄酒中进行苹果酸—乳酸发酵，并测定这些材料对固定化胶粒相对扩散系数的影响。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。
