三．英文文献翻译。

Thiomonas genus is a group of facutatively autotrophi sulphur-oxidizing bacteria formerly belonging to the genus Thiobacillus. Thiomonas genus was created with the former Thiobacillus species Thiomonas intermedia, Thiomonascuprina, Thiomonas perometabolis and Thiomonas thermosulfatabased on their distinctive feature of growing autotrophically,heterotrophically as well as mixotrophically and their phylogenetic relatedness (Moreira and Amils 1997). Recently, a few new Thiomonas strains, which were able to oxidize iron (Dennison et al. 2001; Coupland et al. 2003) or arsenic (Battaglia-Brunet et al. 2002; Bruneel et al. 2003;Coupland et al. 2003), have been isolated from acid-minedrainage. However, there has been no report so far on the application of Thiomonas species in biological deodorization.In our screening programme to obtain active sulphur oxidizers for biological deodorization, a Thiomonas strain that was able to oxidize H2S and some other reduced sulphur compounds was isolated from an activated sludge sample in Singapore. This paper describes the isolation and characterization of this sulphur-oxidizing bacterium. Furthermore,data from a continuous H2S removal study are also presented to demonstrate the potential application of this bacterium in biological deodorization processes.

The hypnotist asks us to think hard about something and relax. When we are relaxed, t he hypnotist gives us some ideas to help us with our problems. Hypnotism can help people to remember things. The police sometimes ask hypnotists to help them. For example, a man sees an accident. He forgets the license number of the car he sees. If he is hypnotized he may remember it.

That may not be what really happened. The police don't hypnotize people who do something wrong. Why not? People who are hypnotized may say something that isn't true.
