Louis Pasteur proved it to be the cause of conversion of ethanol to acetic acid in 1864. It is a benign microorganism which is present everywhere in the environment, existing in alcoholic ecological niches which include flowers, fruits, honey bees, as well as in water and soil. It lives wherever sugar fermentation occurs.〔 It grows best in temperatures that range from 25 to 30 degrees Celsius and in pH that ranges from 5.4 to 6.3. For a long time it has been used in the fermentation industry in order to produce acetic acid from alcohol. ''Acetobacter aceti'' is an obligate aerobe, which means that it requires oxygen to grow.〔 ''Acetobacter aceti'' is economically important because it is used in the production of vinegar by converting the ethanol in wine into acetic acid. The acetic acid created by ''A. aceti'' is also used in the manufacturing of acetate rayon, plastics production, rubber production, and photographic chemicals. ''A. aceti'' is considered an acidophile which means it is able to survive in acidic environments. This is due to having an acidified cytoplasm which makes nearly all proteins in the genome to evolve acid stability. ''Acetobacter aceti'' has become important in helping us understand the process by which proteins can attain acid stability.〔 ==Industrial use== ''Acetobacter aceti'' species is used for the mass production of Acetic Acid, the main component in vinegar. During the fermentation process of vinegar production, the bacteria, ''Acetobacter aceti'' is used to act on wines and ciders resulting in vinegar with Acetic acid. It can be converted by a silicone tube reactor, which aids the fermentation process with oxidation.〔 ''Acetobacter aceti'' has not been reported as a human pathogen. Human skin does not provide the bacteria with the optimum conditions for it to grow, which makes it safe to handle in factories that use the bacteria to produce acetic acid. However, there have been some evidence of it being harmful to plants and other flora even though it exists naturally in the world.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Acetobacter aceti」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
