Abstract

A UASB (Up-flow Anaerobic sludge Blanket)-DHS (Down-flow Hanging sponge) system has been operated for degradation of wastewater containing polyvinyl alcohol (PVA), the water-soluble polymer which is commonly used in textile industry. Anaerobic organisms has been applied to the UASB reactor to investigate the biodegradation of easily decomposable organic matter and depolymerization of PVA.<BR>The results of clone analysis targeting all bacterium of 16S rRNA, Bactemidetes were predominant species in the UASB reactor. Putative PVA degrading bacteria such asAlcaligenes sp., Pseudomonassp., Azoareussp., Xanthomonassp. were detected in the DHS reactor.
