[ Method ] High temperature resistance and culture conditions of six yeast strains were investigated. [Result] Two yeast strains resistant to high temperature (45 ℃ ) with high viable cell number (10^8 cells/ml) were screened, including DQFC2117-1 and DQFC2122-2. [ Conclusion] Strains DQFC2117-1 and DQFC2122-2 could be used as high temperature resistant yeast strains for processing of formulated biological feed.展开更多
