The relationships between germination of the teliospores of Tilletia conroversa Kühn and soil moisture were studied and it was found that the teliospores of TCK could germinate when the soil mass moisture content reached between 1%-28%(relative moisture capacity 3.75%-100%). The suitable moisture for teliospore germination was between 10%-25% of mass moisture capacity or 17.85%-89.3% of relative moisture capacity. The optimal soil relative moisture capacity was between 65%-75%. There was no difference among most TCK isolates tested at the same suitable soil moisture.

In order to understand the adaptation of the microorganisms under the extreme cold environment conditions, the physiological characteristics of the 5 bacterial isolates from the Muztag Am ice core under the different temperatures were investigated. The csp gene was also amplified by PCR technique and the specific primer targeted for the cold shock protein. The observation results showed that there were three phenotypes of microorganisms: psychrophiles growing from 0~23°С(the optimum temperature at 15°C), psychrotolerant with growth range at 0~40°C (the optimum temperature at 23°С), and the thermophile with growth range at 0~45°C(the optimum temperature at 30°C).
