In this study,the media of nutrient agar,modified GM media and ten-fold dilution of modified GM medial were tested in the isolation of halophilic and halotolerant bacteria with the 10% cruse salt as select pressure and using the selected media,the further isolation of 40 soil samples around Tarim basina was also conducted.

The objectives of this study were to (1) develop effective methods for separating and screening actnomycetes from saline environments such as salt lakes and mines and (2) to identify halophilic and halotolerant actinomycetes, thus increase our knowledge about actinomycete resources.

In order to investigate the isolation method of haloalkaliphilic and saline-alkaline tolerance (HSAT) bacteria in Tarim Basin Desert saline-alkaline habitat, a pure culture technique was adopted to explore different pretreatment methods, salinity, and different isolation media on the recovery of HSAT bacteria from different saline-alkaline soil.

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

The halophilic bacteria as for instance Micrococcus roseus,Halobacterium salinarium ,they can grow in the condition of 25～40℃ and pH5.

[Method] Halophilic bacteria HBCC-3 was isolated from Tainan salt field of Lianyungang and its culture conditions were optimized in the orthogonal test.
