酒,自古以來一直陪伴著人類的文明前進,酒在華人的文化中佔有重要的地位,在應酬上不可或缺的就是酒,而相關研究指出,長期過度攝入酒精,容易對個人健康、家庭甚至危害他人安全。亞洲人又因基因缺陷,相當一部分的人體內代謝乙醛 ( 酒精代謝之中間物 ) 的酵素活性較差,也就是乙醛去氫酶 ( Acetaldehyde dehydrogenase,ALDH ) 的基因型突變,導致酵素活性大幅降低,乙醛更容易在體內堆積,造成一系列身體損傷。
本實驗另一個目的則是利用Phenotype MicroArrays ( PM ) 進行YW108生長源分析,目的是找出YW108最適培養條件。過去實驗室培養YW108都以MRS當作主要培養基進行培養,利用PM後得到大量YW108對各式營養源的嗜好性,這些數據在未來YW108進入工業規模生產可以用來改良培養基以提升YW108的產量。

Wine has been accompanying the progress of human civilization since ancient times. In the east, wine plays an important role in the Chinese culture, especially at sociality. According to the report, long-term excessive intake of alcohol is likely to endanger individual health and even harm others. Moreover, about1/4 of Asia people suffer from lower activity of acetaldehyde ( Intermediate of alcohol metabolism ) metabolism due to the gene mutation of acetaldehyde dehydrogenase ( ALDH ). This genetic mutation is the main reason of the significant decrease in ALDH activity and that causes the accumulate of acetaldehyde in the body, and therefore causing a series of physical damage.
Previously, our lab screened a probiotic strain from fermented sour cabbage liquid. The strain was characterized and designated as Lactobacillus brevis YW108 which have ability to metabolize alcohol. However, in human trial YW108 does help human body to metabolize alcohol, but the rate of acetaldehyde metabolism is not as good as expected. Thus for people who suffering from ALDH mutation, L. brevis YW108 accelerate accumulation of acetaldehyde, and get into a drunken state more quickly.
In the first part of this study, we analyze alcohol and acetaldehyde metabolic active fraction of YW108 by enzyme method. Then, genomic and proteomic analysis were used to identify enzymes that may enhance the metabolism of acetaldehyde We found that the intracellular soluble protein fraction of YW108 induced by acetaldehyde has the activity of metabolizing acetaldehyde by enzymeatic analysis. Using proteomic analysis, it was found that YW108 induced by acetaldehyde does exhibit a variety of enzymes related to alcohol metabolism, two of which have the ability to metabolize acetaldehyde. We define these two enzymes as target proteins which can seen as candidate for acetaldehyde reduction product development.
In another part of this study, we used Phenotype MicroArrays ( PM ) for YW108 growth source analysis to find the optimal culture conditions. In the future, we can use these data to improve the medium to increase the yield of YW108 when it enters industrial scale production.
