• UASB with SMD granules was operated with high removal efficiency of COD and NO3--N. • Methanosaetaceae was absolute predominant methanogen in SMD granules. • The methanogen quantity and activity decreased as C/N decreased from 20:1 to 5:1. • Bacterial community succession happened with C/N decreasing.

Less than 50 mg/L nitrobenzene brought little effect on anaerobic sulfate reduction. Kinetics of sulfate reduction under different nitrobenzene contents was studied. Increased nitrobenzene contents greatly changed the bacterial community structure. Genus Desulfovibrio played the key role in anaerobic sulfate reduction process.

基于荧光原位杂交技术的UASB颗粒污泥中苯酚降解微生物生态位分化研究 Article

利用荧光原位杂交(FISH)和克隆文库构建技术,研究了厌氧污泥床反应器处理含酚废水时所收获的颗粒的微生物群落结构。研究发现,互营杆菌(Syntrophorhabdaceae)和隐杆厌氧菌(Cryptanaerobacter)的克隆是苯酚降解的主要原因。为了准确地对隐杆厌氧菌的克隆进行分类归属,需要利用近全长的16S核糖体RNA(rRNA)基因序列进行进化分析。设计了三种寡核苷酸探针用于检测以下三个分类群:互营杆菌、隐杆厌氧菌和互养菌。对厌氧颗粒薄片的FISH 分析显示细菌和古菌呈随机分布。然而,互营杆菌、隐杆厌氧菌和互养菌分布明确。在颗粒细胞的外层发现了隐杆厌氧菌和互养菌,两者关系密切,而互营杆菌则位于颗粒细胞的深层。细菌之间的代谢联系和对底物的亲和力很可能是造成这种特殊分布的原因。研究人员观察到颗粒污泥中苯酚的降解主要通过以下方式进行:首先,隐杆厌氧菌将苯酚转化为苯甲酸盐,然后被互养菌降解为乙酸盐。苯酚的这种互饲降解发生在颗粒表面附近,此处苯酚浓度较高。在苯酚浓度较低的颗粒深部,互营杆菌将苯酚降解为乙酸盐。结果表明,互营杆菌不太可能产生苯甲酸盐,并将其作为中间产物来喂养邻近的生物,这一点与以往研究所提出的理论相矛盾。
