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...
