菌种品系及VA对黄孢原毛平革菌降解两种染料的影响

黄孢原毛平革菌的不同品系与染料亚甲基蓝的比布列希猩红的浅层静培养表明，对于亚甲基蓝而言，ME-446降解能力最强，OGC101和BKM-F-1767相似；以比布列希猩红为底物，则OGC101最好，ME-446其次，最后为BKM-F-1767。虽然外源藜芦醇（VA）的补充在培养初期有利于染料脱色降解率的提高；但一周后，与不添加VA的样品比较，脱色降解率接近或相等。这说明菌的品系存在降解能力的差异，完整菌体自身合成的VA足以维持降解培养体系的正常运作。

Effects of Strains and Veratryl Alcohol on Degradation of Two Kinds of Dyes by Phanerochaete chrysosporium

The shallow static cultures of methylene blue and Biebrich scarlet with different strains of Phanerochaete chrysosporium showed: to methylene blue, degradation efficiency of ME-446 was best, that of OGC101 was similar to BKM-F-1767; to Biebrich scarlet, the first was OGC101, the second M-446, and the last BKM-F-1767. The extraneous supply of VA was advantaged to decolorization and degradation of dyes during early stages, but a week later, there was no significant difference in the samples with addition of VA and without VA. The results showed that various strains had different abilities of decolorization and degradation; the VA that the intact fungus culture self-synthesized was enough to support the normal operation of degradative culture system.
