Adopting fuzhuan tea as bacteria source,twenty strains of 3-phenoxybenzoate acid( 3-PBA) degrading"golden flower fungi"were screened. Strain ET1 isolated from the fuzhuan tea could completely degrade 100mg/L 3-PBA in the PD medium in 7d. Based on the analysis of morphological characteristics and its sequence( GenBank Accession No. KF317836),strain ET1 was identified as Eurotium cristatum. Kinetic research indicated that the degradation of 3-PBA by strain ET1 could be described by a first-order kinetics model. The degradation half-life of 3-PBA was 1. 7 to 3. 2d over a certain range of 3-PBA concentration,temperature and pH,which was much shorter than its natural half-life. The pH were found to influence the reaction rate obviously but the concentration of 3-PBA and temperature had little effect on reaction rate.
