And the conditions in cell suspension culture of Mikania micrantha were studied. The results showed that sucrose was the compatible carbon sucrose, and 30g/L sucrose concentration can satisfy the growth of Mikania micrantha cell; ammonium was absorbed under different sucrose concentration that haven't demonstrated significant specificity, and was completely absorbed on the lag phase and the early logarithmic phase; while nitrate was mainly absorbed on logarithmic phase. The density-dependent of Mikania micrantha cell starting to grow and density-inhibited of cell growth were proposed, the fittest inoculating quantity of Mikania micrantha in cell suspension culture was 40g/L.

The results of batch experiments showed that the anaerobic biodegradation kinetics of 2-CNB and 4-CNB by granular sludge were follwed by first-order reaction. The nitro groups of 2-CNB and 4-CNB were more easily attacked by electron than chlorines and they were reductively biotransformed to amino groups under anaerobic conditions. The acclimated anaerobic granular sludge, which could dechlorinate 4-chloroanline to aniline, showed that it had the ability of para-dechlorinating. The anaerobic biodegradating on pathway of 2-CNB and 4-CNB were suggested as follows:AbstractIn ZVI(zero-valent iron, Fe0)-reduction system, the nitro groups of 2-CNB and 4-CNB were reductively transformed to amino groups.
