BIODEGRADATION OF POLLUTANTS WITH BACTERIA USING BUTANE.

摘要

BACTERIES USING BUTANE ARE USED TO DEGRAD HYDROCARBON CONTAMINANTS AS FOR EXAMPLE TRICLOROETHYLENE (TCE). IN SITU OR EX SITU TECHNIQUES CAN BE USED TO REDUCE OR ELIMINATE HYDROCARBON CONTAMINANTS FROM LIQUID, GASEOUS AND SOLID SOURCES. IN A PREFERRED EMBODIMENT, TCE CONCENTRATIONS ARE REDUCED IN VARIOUS MEDIUM MEDIA BY CONTACTING A SOURCE OF WATER CONTAMINATED WITH BACTERIA THAT USE BUTANE IN THE PRESENCE OF OXYGEN TO DEGRAD THE TCE BY COMMITABOLISM OR DIRECT. BACTERIA USING BUTANE SUITABLE INCLUDE pseudomonas Variovorax, Nocardia Chryseobacterium, Comamonas, Acidovorax, Rhodococcus, Aureobacterium, Micrococcus, Aeromonas, STENOTROPHOMONAS, Sphingobacterium, Shewanella, Phyllobacterium, Clavibacter, Alcaligenes, GORDONA, Corynebacterium and Cytophaga. THE BACTERIA THAT USE BUTANE HAVE A RELATIVELY LOW TOXICITY TCE, IN RELATION TO THE BACTERIA THAT USE CONVENTIONAL METHANE AND SHOW AN IMPROVED ATTITUDE TO DEGRAD THE TCE.
