Abstract
Large amounts of herbicide mainly including TCDD (Tetra-chlorinated dibenzo-p-dioxin) had been sprayed during Vietnam War. Due by chlorine atoms TCDD showed strong biological toxicity and recalcitrant to degradation. Therefore, dechlorination is critical step and dechlorination and degradation of TCDD under aerobic, anaerobic, or anaerobic-aerobic sequential conditions, several microcosms were prepared. Ten ml slurry samples (50% v/v) of TCDD contaminated soil from A Luoi, Vietnam was distributed into 100 ml serum bottles and set four different conditions. As a result, microbial community was divided by type of treatments, briefly, oxygen and organic acids governing community structure. Under anaerobic conditions Classes Acidobacteria and Chloroflexi dominated with time, however, no diverse bacterial groups were competed in aerobic conditions. The results implied that microbial community structure could be guided with appropriate treatment.on is critical step and dechlorination and degradation of TCDD under aerobic, anaerobic, or anaerobic-aerobic sequential conditions, several microcosms were prepared.
