The numerical distribution of halophilic bacteria and halotolerant bacteria in Aydin Lake and the surrounding area

Abstract:
In the present study in the numerical distribution of halophilic bacteria and halotolerantbacteria in Aydin L ake and the surrounding area was inrestigated while salt was the sole growth limiting factor. The results showed thatthe numerical distribution ofhalophilic bacteria and halotolerantbacteria varsed in different seasons and differentsampling site.In lake water,the halophilic bacteria was more than halotoler- ant bacteria in spring and autumn,but under low temperature condition in winter while the saltconcentra- tion in water was reduced by depositing,the opposite was observed.Compared with the water,there were relative steady organic content and temperature in the soil and the number of halotolerant microbe in soil samples were always larger than that of halophlic bacteria.The general distribute pattern was:the farther away from lake there were the few high salt dependentbacteria and the more low saltdependentones. By different salt concentration media,61 haloakaliphilic archaea were screened from a total of1 73 strains,and several new spices were obtained,their taxonomic characteristics and result will be described in another paper.
