连云港台南盐田中嗜盐和耐盐菌群分布的调查

2001年、2002年冬春夏3季在连云港台南盐场取卤水和底泥样品，对嗜盐菌和耐盐菌的分布状况进行调查．结果表明，不同盐度(6．6％-32．3％)盐池中栖息着不同的菌群，夏季嗜盐菌和耐盐菌数量较高，主要以盐单胞菌属、海球菌属、盐水球菌属等非芽孢菌为优势菌，低盐度(6．6％-9．9％)池中耐盐菌数量高于嗜盐菌，中盐度(13．8％-17．4％)池中耐盐菌数量接近嗜盐菌，高盐度(20．2％-32．3％)池中主要为极端嗜盐菌．此外，底泥中嗜盐菌和耐盐菌的数量一般高于卤水中．

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.
