The overview of HCB effect on natural microbial dechlorination was summarized in
Table 4.5. The results, shown in Figure 4.3 and Table 4.5, revealed that a consortium
and culturing condition of S4 promoted the HCB-dechlorination better than S3, in
addition HCB at 200 ppm could not affect dechlorinating microbes in Hua-Lum-Poo
