| Environmental txoj hmoo | Tshuaj lom neeg.Nyob rau hauv aerobic tej yam kev mob, biodegradation cov khoom yuav muaj xws li 1,2-dichlorobenzene, 1,3-dichlorobenzene, 1,4-dichlorobenzene, thiab carbon dioxide (Kobayashi thiab Rittman, 1982). Kev sib xyaw ntawm cov kab mob hauv av los yog Pseudomonas sp. hloov 1,2,4-trichlorobenzene rau 2,4,5- thiab 2,4,6-trichlorophenol (Ballschiter thiab Scholz, 1980). Thaum 1,2, 4- trichlorobenzene tau statically incubated nyob rau hauv qhov tsaus ntuj ntawm 25 degree nrog poov xab extract thiab tswm nyob rau hauv cov dej khib nyiab inoculum, tseem ceeb biodegradation tshwm sim, nrog gradual acclimation tom qab ib tug deadaptive txheej txheem nyob rau hauv subcultures tom ntej. Ntawm qhov concentration ntawm 5 mg / L, 54, 70, 59, thiab 24% poob tau pom tom qab 7, 14, 21, thiab 28-d lub sij hawm incubation, feem. Ntawm qhov concentration ntawm 10 mg / L, tsuas yog 43, 54, 14, thiab 0% tau pom tom qab 7, 14, 21, thiab 28-d lub sij hawm incubation, raws li (Tabak li al., 1981). Nyob rau hauv activated sludge,<0.1% mineralized to carbon dioxide after 5 d (Freitag et al., 1985). Hauv cov kab lis kev cai enrichment tau muab los ntawm qhov chaw muaj kab mob hauv Bayou d'Inde, LA, 1,2, 4- trichlorobenzene underwent reductive dechlorination mus rau 1,3- thiab 1,4-dichlorobenzene ntawm tus txheeb ze molar yields ntawm 4 thiab 96%, feem. Qhov siab tshaj plaws dechlorination tus nqi, raws li cov qauv pom zoo Michaelis-Menten, yog 4.6 nM / d (Pavlostathis thiab Prytula, 2000). Nto Dej.Kwv yees ib nrab neej ntawm 1,2,4-trichlorobenzene (0.5 ug/L) los ntawm kev sim marine mesocosm thaum lub caij nplooj ntoos hlav (8–16 degree), lub caij ntuj sov (20–22 degree), thiab lub caij ntuj no (3–7 degree) yog 22, 11, thiab 12 d, ntsig txog (Wakeham li al., 1983).
