Gas-pak is a method used in the production of an anaerobic environment. It is used to culture bacteria which die or fail to grow in presence of oxygen (''anaerobes''). These are commercially available, disposable sachets containing a dry powder or pellets, which, when mixed with water and kept in an appropriately sized airtight jar, produce an atmosphere free of elemental oxygen gas (O2). They are used to produce an anaerobic culture in microbiology. 〔Textbook of Microbiology by Prof. C P Baveja, ISBN 81-7855-266-3〕 〔Textbook of Microbiology by Ananthanarayan and Panikar, ISBN 81-250-2808-0〕 〔http://ftp.ccccd.edu/dcain/CCCCD%20Micro/gaspakjar.htm "GasPak System". Accessed October 27, 2009.〕 It is a much simpler technique than the McIntosh and Filde's anaerobic jar where one needs to pump gases in and out. == Constituents of gas-pak sachets== #Sodium borohydride - NaBH4 #Sodium bicarbonate - NaHCO3 #Citric acid - C3H5O(COOH)3 #Cobalt chloride - CoCl2 (catalyst) The addition of a Dicot Catalyst maybe required to initiate the reaction. 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「Gas-pak」の詳細全文を読む スポンサード リンク
