Q0102b is an actinomycete strain with wide fungal repression spectrum.The cultural conditions including 7 carbon and 4 nitrogen sources were evaluated for its growth amount and antifungal activity.The results showed that the strongest repression on Fusarium avenaceum when corn starch and yeast extract were included as carbon and nitrogen sources.Based on orthogonal test,the best cultural condition for Q0102b's strong antifungal activity is 40 g/L corn starch,7 g/L yeast extract,10 g/L NaCl at pH 8.0 and 28℃...
