The numerical distribution of halotolerant bacteria and halophilic bacteria from brine pan in tainan salt field of lianyungang

The study on the numerical distribution of halotolerant and halophil ic bacteria in Tainan salt field of Lianyungang was carried out in the three of season of winter,sping and summer in from 2001 to 2002,and a lot of water and so il samples were collected in brine pan containing different salinity(6.6%-32 .3% ).The results showed that the number of halotolerant and halophilic bacteri a changed in different season and sampling site,the greatest amount of them app ears in summer,was mostly Halomonas,Marinococcus,Salinicoccus,etc.The amount of halotolerant bacteria was greater than that of halophilic bacteria from water sa mples in low salt pond(6.6%-9.9% ),as much as in medium salt pond(13.8%-17.4% ),extreme halophiles was preponderant bacteria in high salt pond(20.2%-32.3% ).In addition,compared with the water samples,there were always more t han the number of halotolerant and halophilic bacteria in soil samples.
