Premise of the study : Phenolic compounds exuded by roots have been implicated in allelopathic interactions among plants. Root enzymes that destroy phenolics may protect plants against allelopathic inhibition and thus may aid in invasiveness. Phen

Environmental soil contamination at an industrial site in Marion, Ohio (USA) with tetrachloroethene (perchloroethene, PCE) resulted in residual cis-1, 2-dichloroethene (DCE) contamination that had not declined after more than 15 years. Microcosm slur

2,4,6-trichlorophenol (2,4,6-TCP) was successfully and completely degraded in a two-stage anaerobic–aerobic biological process in which the initial step was conducted anaerobically, resulting in the reductive dechlorination of the target compound t

Anaerobic bacteria are now known to be far more diverse and to possess greater metabolic capabilities then was generally believed even a few years ago. Research published in the past decade has revealed a variety of potentially useful catabolic activ

The adsorption of 12 mono-, di-, and trichlorophenols from aqueous solutions on different activated carbons was studied. Distilled water and a minimal salt medium solution previously used in biotreatment studies with anaerobic organisms were used as

The adsorption of 4-chlorophenol (4-CP) on activated carbon was studied experimentally both in the presence and in the absence of an inactivated anaerobic biofilm on the surface of carbon pellets. The presence of the biofilm markedly decreased the ra

The effect of vitamins on the aerobic degradation and dechlorination of 2-chlorophenol and 4-chlorophenol by Pseudomonas pickettii, strain LD1, and 4-chlorobiphenyl by Pseudomonas sp. strain CPE1 was determined. These microorganisms are capable of us

A strain of Xanthomonas (Pseudomonas) maltophilia utilized toluene and xylene at the same rate in a well-mixed system containing excess nitrate and either 2% oxygen or no oxygen. Toluene utilization was much more rapid when 20% oxygen was provided. T

The adsorption of sodium benzoate, 2,4-dichlorophenol and 2,4,6-trichlorophenol onto five activated carbons made from Northern Ireland lignite is reported. A two-stage process consisting of chemical activation during the charring of the lignite, foll

A mathematical model was developed to describe the sequential dechlorination of 2,4,6-trichlorophenol to 2,4-dichlorophenol, 4-chlorophenol and phenol. Each compound was assumed to be degraded according a Michaelis-Menten expression. Experimental dat
