Abstract:
An oxalate-degrading Enterococcus faecalis was isolated from human stools under anaerobic conditions. The bacteria required a poor nutritional environment and repeated subculturing to maintain their oxalate-degrading ability. The E. faecalis produced 3 proteins (65, 48, and 40 kDa) that were not produced by non-oxalate-degrading E. faecalis as examined by SDS-PAGE. Antibodies against oxalyl-coenzyme A decarboxylase (65 kDa) and formyl-coenzyme A transferase (48 kDa) obtained from Oxalobacter formigenes (an oxalate-degrading anaerobic bacterium in the human intestine) reacted with 2 of the proteins (65 and 48 kDa) from the E. faecalis as examined by Western blottings. This is the first report on the isolation of oxalate-degrading facultative anaerobic bacteria from humans.
