• Five taxa of diatoms, Achnanthes brevipes v. intermedia, Navicula muticopsis, Nitzschia palea, Pinnularia borealis and Tropidoneis laevissima, were isolated from the samples collected from five saline lakes, Lake Zakuro, Lake Akebi, Lake Nurume of Langhovde and Lake Suribati and Lake Hunazoko of Skarvsnes. From the successive cultures of the isolated diatoms with agar containing various concentrations of NaCl, it is clarified that Tropidoneis laevissima is halophilic. Achnanthes brevipes v. intermedia showed a wide range of tolerance to NaCl concentration (0-25%) in agar. Navicula muticopsis had a narrow range (0-5%) of halotolerance. The range of halotolerance of the others was intermediate between Achnanthes and Navicula.
