Effects of Plant Growth Regulators on Taxol Biosynthesis by an Endophytic Fungus

Abstract:

In this study,the effect of plant growth regulators on the taxol biosynthesis by Metarhizium anisopliae Tax-27 was investigated.The results showed that the titer of taxol was 670.49 μg/L,838.11μg/L,942.57μg/L,455.72 μg/L,450.48 μg/L when 4 mg/L gibberellin(GA3),60μmol/L methyl jasmonate(MeJA),25mg/L chlormequat chloride(CCC),4 mg/L 6-benzylaminopurine(6-BA),and 4 mg/L 1-naphthlcetic acid(NAA) was feed to the fermentation broth,respectively..However,the addition of GA3,MeJA,CCC inhibited the mycelial growth of M.anisopliae Tax-27,on the other hand,the addition of 6-BA and NAA significance increased the mycelia growth.
