population dynamics of an introduced bacterium degrading chlorinated benzenes in a soil column and in sewage sludge.	the capacity of the beta-proteobacterium pseudomonas sp. strain p51, which degrades chlorinated benzenes, to metabolize 1,2,4-trichlorobenzene (tcb) under environmental conditions was tested by its release into two experimental systems. the first system consisted of laboratory scale microcosms which were operated with and without the addition of tcb and which were inoculated with sludge from a wastewater treatment plant. the second system consisted of a non sterile, water saturated soil column. ...	1999	10466200
metabolism of acrylate to beta-hydroxypropionate and its role in dimethylsulfoniopropionate lyase induction by a salt marsh sediment bacterium, alcaligenes faecalis m3a.	dimethylsulfoniopropionate (dmsp) is degraded to dimethylsulfide (dms) and acrylate by the enzyme dmsp lyase. dms or acrylate can serve as a carbon source for both free-living and endophytic bacteria in the marine environment. in this study, we report on the mechanism of dmsp-acrylate metabolism by alcaligenes faecalis m3a. suspensions of citrate-grown cells expressed a low level of dmsp lyase activity that could be induced to much higher levels in the presence of dmsp, acrylate, and its metabol ...	1999	10543825
biotransformation of monoterpenes, bile acids, and other isoprenoids in anaerobic ecosystems.	isoprenoic compounds play a major part in the global carbon cycle. biosynthesis and mineralization by aerobic bacteria have been intensively studied. this review describes our knowledge on the anaerobic metabolism of isoprenoids, mainly by denitrifying and fermentative bacteria. nitrate-reducing beta-proteobacteria were isolated on monoterpenes as sole carbon source and electron donor. thauera spp. were obtained on the oxygen-containing monoterpenes linalool, menthol, and eucalyptol. several str ...	1998	9990726
