Microcosms may potentially be used as tools for evaluating the fate and effects of genetically engineered microorganisms released into the environment. Extrapolation of data to the field, however, requires that the correspondence between mi...
Interactions of bacteria and microflagellates in sequencing batch reactors exhibiting enhanced mineralization of toxic organic chemicals [0.03%]
序批式反应器中细菌和微型鞭毛生物的相互作用及其对有毒有机化合物增效矿化的研究
