Isolation and Selection of Bacteria Chemotactic to Chlorobenzene and Other Organic Chlorinated Compounds Nowadays, polluting compounds are commonly present in the environment, which seriously affect human’s health. However, the current methods for detecting these compounds are costly, expertise-requiring and technically complicated as well. Thus, in this work, we studied the applicability of the chemotactic responses of bacteria toward some popular polluting organic chlorinated compounds (e.g. chlorobenzene) in order to develop a biological method that is simple, economical, and time-saving to detect those compounds in environmental samples. From 169 bacterial strains isolated from different national parks such as Cuc Phuong, XuanThuy and Tam Dao, three bacterial strains (HTD 3.8, HTD 3.12 and HTD 3.15) having the capability of negative chemotaxis towards chlorobenzene could be selected. Among them, HTD 3.8 displayed a better response to chlorobenzene, with a threshold co
