In this study, the microbial degradation characteristics of
butyl benzyl phthalate (BBP) were studied by using Phanerochaete chrysosporium. Results showed
Phanerochaete chrysosporium can effectively degrade BBP and the degradation efficiency can reach
90% in 2 days. This strain can use BBP as sole carbon source. The biodegradation of BBP by
Phanerochaete chrysosporium fits for first-order kinetics (Inc=-K(b)t+a), which are Inc = -
0.0445x + 4.4235, Inc = -0.0404x + 5.1221, Inc = -0.0389x + 5.6363, respectively, for the
concentration of 100mg/L, 300mg/L, 500mg/L. The biodegradation rate constants are 0.0445 d(-1)
0.0404 d(-1), 0.0389 d(-1), respectively. The biodegradation rate constant reduces with the
increase of the concentration of BBP, indicating BBP has inhibitory effect on Phanerochaete
chrysosporium, especially under high concentration. The high performance liquid chromatography
(HPLC) profile of the metabolites indicated the accumulation of two major products except for
phthalic acid (PA). These two products were characterized by high performance liquid
chromatography mass spectrometry (HPLC/MS) as mono-n-butyl phthalate (MBuP) and monobenzyl
phthalate (MBzP).
