| 摘 要： | 生化铁碱溶液催化法气体脱硫方法（简称DDS法）具有良好脱硫效果，但是DDS溶液在脱硫后会导致脱硫能力降低，为了达到使DDS脱硫残液得到再生的目的，从自然环境中筛选能够使DDS脱硫残液得到再生的微生物并对其进行了研究。通过富集培养及纯化，从黑龙江省五大连池火山口附近土样中筛选出一株碱性条件下脱除硫酸盐的菌株WT-1。对该菌株的生长曲线进行了测定，培养4～6 h菌株进入对数期，20 h左右到达稳定期。并研究了温度、pH值和摇床转速对其生长特性和活性的影响，结果表明，该菌株的最适生长条件为：温度35～45℃，pH值8，摇床转速120 r/min。同时，脱硫试验表明WT-1确实具有脱除硫酸盐的能力。
