Abstract
In the previous work we reported that 1,2-hydroxypropyl-β-cyclodextrin (β-HPCD) could accelerate the biodegradation rate of PAHs by increasing the solubility of PAHs through detaining of PAHs in the cavity of β-HPCD. The aim of this study is to screen for chiefer material which could substitute the β-HPCD, because the β-HPCD is too expensive for bulk usage. Low molecular weight PAHs, saturated hydrocarbons, metabolites of PAHs, several plant terpenoids, β-cyclodextrin and mixed form of cyclodextrin were tested for the enhancement of PAHs biodegradation. As a result, most of the tested materials could enhance the biodegradation rate of benzo[a]pyrene, more or less, except hexadecane, β-cyclodextrin and thymol. The enhancement was not affected by the concentration of additives. Among the additives, the addition of 1% mixed form of cyclodextrin could enhance the BaP degradation rate comparable to that of β-HPCD. Therefore, mixed form of cyclodextrin could substitute the β-HPCD to increase the degradation rate of HMW-PAHs by N. pentaromativorans US6-1.
