英文摘要：

This paper is focused on introducing our research results of the characteristic features of the so-called cell fusion technque and the ways of its application to constructing engineering strains for sewage treatment ,Since the cell fusion technique is likely to be the one unfamiliar to our readers ,we would like to offer a brief presentation on it from its working priciple,developmental history,some popular fusion methods as well as its latest advancements.As we know,it enjoys a long history,which is acknowledged as a starting point：As a matter of fact,Okada found in 1958 that Sendai virus could be brought into ascites to make the cancer cell fuse.Since then,quite a number of fusion methods have been introduced,such as virus cell fusion,chemical-fusion ,electro-fusin ,laser-fusion,inactivated protoplasts fusion,etc.Next,we would like to make a comparison between its principle,its adyantages and disadvantages. The latest developments of the technique may involve microfluidic chip-based,high-throughout cel fusion chips ,as well as the ion beam cell fusion ,all of which help to result in the highly-efficient modern electronic and chip technique,though not yet widely used.The branches of the technique can be said to stand for its working principles in different areas,with some of them used to treat sewage containing chlorine,polyvinyl alcohol（PVA）,heavy metals and other industrial waters by protoplast fusion .THe results of the wide application of the technique,significant and fruitful,suggesting a great potential in further application .And,finally,we have also analyzed problems with its application ,such as security problem and so on .However,it is also necessary to point out its development directions for the cell fusion technique in constructing engineering strains of water treatment.
