請(qǐng)問butyl septa 是什么?
|
|
各位大俠,今天看文獻(xiàn)看到以下論述 Glass bottles of 1250 mL containing 500 mL of diluted centrifuged piggery wastewater (1:4 and 1:8 dilutions with tap water)were inoculated with the target microalga species at initial concentrations ranging from 4 to 6 mg DW L-1 (Dry Weight) and activated sludge bacteria at 3 mg DW -1.The bottles were then flushed with He in order to establish an initial bioreaction environment totally deprived from O2, and immediately closed with butyl septa and sealed with plastic caps. Under these conditions, the biodegradation of piggery wastewater can only proceed driven by photosynthetic oxygenation. 針對(duì)上段論述中有幾個(gè)問題想請(qǐng)教各位大俠 1、butyl septa 是什么東西?是將這個(gè)纏在玻璃瓶口然后用塑料蓋密封的意思嗎? 2、玻璃瓶密封之后,里面產(chǎn)氣會(huì)使得瓶?jī)?nèi)氣壓變大,不會(huì)有瓶子爆裂的危險(xiǎn)嗎?或者氣壓變大影響微生物生長(zhǎng)嗎? 3、論述中提到He氣趕氧氣,可以用氮?dú)獯鎲幔?br /> de Godos I, Vargas VA, Blanco S, González MCG, Soto R, García-Encina PA, et al. A comparative evaluation of microalgae for the degradation of piggery wastewater under photosynthetic oxygenation. Bioresour Technol 2010;101:5150–8. |

1.一種材料: http://www.labhut.com/20mm-ptfe-grey-butyl-septa.html 密封 2.基本上沒什么影響吧 3.一般都是用氮?dú)猓馕覀儗?shí)驗(yàn)室還搞不到 |
