研究了恶臭假单胞菌F1、洋葱伯克霍尔德菌G4和施氏假单胞菌OX 1对甲苯、三氯乙烯(TCE)、四氯乙烯(PCE)、顺式-1,2-二氯乙烯(cis-DCE)、反式-1,2-二氯乙烯(trans-DCE)、1,1-二氯乙烯(1,1-DCE)和氯乙烯(VC)的趋化反应。施氏毕赤酵母OX 1和恶臭毕赤酵母F1对甲苯、PCE、TCE、所有DCE和VC具有趋化性。B。洋葱G4对甲苯、PCE、TCE、cis-DCE、1,1-DCE和VC具有趋化性。施氏疟原虫OX 1在邻二甲苯蒸气上生长的趋化性比在邻甲酚蒸气上生长的强得多。touABCDEF中甲苯-邻二甲苯单加氧酶(ToMO)的表达似乎是正趋化性吸引所必需的,并且touR(ToMO调节)基因的吸引力更强。
The chemotactic responses of Pseudomonas putida F1, Burkholderia cepacia G4, and Pseudomonas stutzeri OX1 were investigated toward toluene, trichloroethylene (TCE), tetrachloroethylene (PCE), cis-1,2-dichloroethylene (cis-DCE), trans-1,2-dichloroethylene (trans-DCE), 1,1-dichloroethylene (1,1-DCE), and vinyl chloride (VC). P. stutzeri OX1 and P. putida F1 were chemotactic toward toluene, PCE, TCE, all DCEs, and VC. B. cepacia G4 was chemotactic toward toluene, PCE, TCE, cis-DCE, 1,1-DCE, and VC. Chemotaxis of P. stutzeri OX1 grown on o-xylene vapors was much stronger than when grown on o-cresol vapors toward some chlorinated ethenes. Expression of toluene-o-xylene monooxygenase (ToMO) from touABCDEF appears to be required for positive chemotaxis attraction, and the attraction is stronger with the touR (ToMO regulatory) gene.
