Like other strains of ''Clostridium'', it is an anaerobic, rod-shaped bacterium that produces oval, subterminal endospores and is commonly found in soil. Unlike ''Clostridium botulinum'', it does not produce the botulinum neurotoxins. In colonized hosts, it serves a symbiotic rather than pathogenic role. In the human microbiome, ''C. sporogenes'' serves as a symbiotic bacteria that uses tryptophan to synthesize indole and then subsequently (IPA)〔 – a type of auxin (plant hormone) – which serves as an incredibly potent antioxidant within the human body and brain.〔〔〔 IPA is an even more potent scavenger of hydroxyl radicals than melatonin.〔〔 Similar to melatonin but unlike other antioxidants, it scavenges radicals without subsequently generating reactive and pro-oxidant intermediate compounds. ''C. sporogenes'' is the only bacteria known to synthesize 3-indolepropionic acid ''in vivo'' at levels which are subsequently detectable in the blood stream of the host. It is being investigated as a way to deliver cancer-treating drugs to tumours in patients.〔(BBC News "Soil bacterium helps kill cancers." )〕 ''C. sporogenes'' is often used as a surrogate for ''C. botulinum'' when testing the efficacy of commercial sterilisation. ==References== 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「Clostridium sporogenes」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.
