高铁离子浓度环境下氧化亚铁硫杆菌的生长行为

对氧化亚铁硫杆菌在高铁离子浓度下的生长情况进行了研究。在初始Fe2+]=10、30、50、70、90g/L的高铁离子浓度9K培养基中培养氧化亚铁硫杆菌,定时测培养基中的细菌数、pH值及氧化还原电位(Eh)和Fe2+的终浓度,试验得出:Fe2+]为30g/L时,氧化亚铁硫杆菌的生长最为旺盛,浓度达到9×107个/mL;在接种量为10%、pH值为1.6的情况下,氧化亚铁硫杆菌的Fe2+氧化速率最高,分别达到2.87g/(L.d)和2.67g/(L.d)。

Ferrosoferric Oxide Thiobacillus Growing Behaviour in Circumstance of High Thick Iron Ion

Study works were conducted on Ferrosoferric oxide Thiobacillus growing condition in high thick iron ion. At beginning, ferrosoferric oxide thiobacillus was cultivated in a culture with = 10, 30, 50, 70 and 90 g/L and high iron ion thickness of 9K.The number of bacterium in culture, pH value, oxidation reduction potential (Eh) and final thickness of Fe+{2+} are measured at regular time. It is indicated from the tests that with Fe+{2+}]= 30g/L, the Ferrosoferric oxide thiobacillus grows very well and the thickness of that is up to 9×10+7/mL. In case that inoculation percent is 10% and pH is 1.6, the Fe+{2+} of Ferrosoferric oxide has a highest oxidation rate up to 2.878/ (L·d ) and 2.67g/(L·d).
