ABSTRACT
pH, affects of different alkaline materials KOH, K 2CO 3, NaOH, Na 2CO 3 on the growth, and NaCl, KCl tolerance of 29 isolates from the saline and alkaline soils in Xinjiang and Qinghai Provinces of China and 1 type strain were studied. Results showed that only a few alkaliphilic actinomycetes were Na +-obligately dependent, and K +-sensitive. Some alkaliphilic actinomycetes were CO 3 2- -sensitive, and NaCl, KCl could inhibit their growth. 4 kinds of alkaline materials had no affect on growth of alkaliphilic Nocardiopsis, and these strains showed high tolerance to NaCl, KCl. So it was presumed that only K + and CO 3 2- obligately dependent alkaliphilic Actinomycetes maybe exist in alkaline environments.
