Notes:
In this paper, a novel and highly efficient hydroxyapatite (HA) carrier for cultivatinghydrocarbon degradation bacteria (HDB) is introduced. The HA particles synthesized through a sol-gelmethod and different heat treatments were characterized by X-ray diffraction (XRD), scanning electronmicroscopy (SEM) and BET method. The microbial amount and activities of HDB cultivated on HAcarriers were quantitatively investigated in order to assess their enriching capabilities. The results showedthat HA synthesized at 550°C and the one without calcination could enrich HDB 3 and 2 magnitudeorders more than the activated carbon, respectively. Mechanisms of bacterial enrichment on HA andactivated carbon were also studied, and it is believed that the high bioactivity and the surface morphologyof HA were responsible for the efficient reproduction of HDB. It is concluded that HA is a potentialcandidate to replace the conventionally used activated carbon as a novel carrier applied in the filed ofbioremediation for oil contaminated soil
