新方法提高生物製氫能力

據外國媒體報道：圖爾庫大學和芬蘭VTT技ji術shu研yan究jiu中zhong心xin的de一yi項xiang聯lian合he研yan究jiu表biao明ming，通tong過guo將jiang細xi胞bao附fu著zhe在zai透tou明ming的de納na米mi纖xian維wei素su薄bo膜mo上shang，可ke以yi顯xian著zhe提ti高gao光guang合he微wei生sheng物wu細xi胞bao從cong太tai陽yang能neng產chan生sheng生sheng物wu氫qing的de能neng力li。該gai方fang法fa也ye有you望wang增zeng強qiang微wei藻zao細xi胞bao生sheng產chan其qi他ta生sheng物wu化hua學xue物wu質zhi。結jie果guo發fa表biao在zai著zhu名ming的de期qi刊kan《Journal of Materials Chemistry A》上。

圖爾庫大學分子植物生物學副教授Yagut Allahverdiyeva及ji其qi團tuan隊dui利li用yong光guang合he微wei藻zao和he藍lan細xi菌jun的de工gong作zuo被bei認ren為wei是shi最zui有you前qian途tu的de生sheng物wu經jing濟ji方fang式shi。由you於yu簡jian單dan的de工gong程cheng生sheng物wu膜mo結jie構gou，光guang合he作zuo用yong捕bu獲huo的de太tai陽yang能neng可ke以yi以yi有you效xiao和he受shou控kong的de方fang式shi導dao入ru所suo需xu的de最zui終zhong產chan品pin。

這zhe項xiang研yan究jiu的de關guan鍵jian點dian在zai於yu固gu定ding細xi胞bao，即ji將jiang細xi胞bao結jie合he到dao凝ning膠jiao樣yang物wu質zhi的de表biao麵mian內nei或huo表biao麵mian上shang，由you此ci細xi胞bao代dai謝xie從cong微wei生sheng物wu的de生sheng長chang繁fan殖zhi轉zhuan變bian為wei所suo需xu化hua合he物wu的de生sheng成cheng。與yu細xi胞bao在zai生sheng長chang培pei養yang基ji中zhong的de正zheng常chang培pei養yang相xiang比bi
，細xi胞bao附fu著zhe在zai薄bo的de透tou明ming薄bo膜mo上shang顯xian著zhe減jian少shao了le光guang能neng的de損sun失shi。適shi合he固gu定ding的de材cai料liao必bi須xu是shi多duo孔kong的de，透tou明ming的de
，耐nai水shui的de，並bing且qie與yu藻zao細xi胞bao具ju有you生sheng物wu相xiang容rong性xing。

納na米mi纖xian維wei膜mo符fu合he所suo有you這zhe些xie要yao求qiu。它ta是shi迄qi今jin使shi用yong的de材cai料liao的de有you效xiao替ti代dai品pin
，具ju有you相xiang對dui優you秀xiu的de機ji械xie耐nai久jiu性xing和he較jiao高gao的de孔kong隙xi率lv。該gai研yan究jiu揭jie示shi了le納na米mi纖xian維wei素su與yu產chan氫qing綠lv藻zao和he藍lan藻zao的de高gao相xiang容rong性xing。另ling外wai，納na米mi纖xian維wei素su膜mo的de綠lv藻zao細xi胞bao的de氫qing產chan量liang明ming顯xian高gao於yu使shi用yong藻zao酸suan鹽yan時shi的de產chan氫qing量liang。
