摘要: Microbial removal of nitrate from drinking water was studied in laboratory columns packed with unprocessed short fiber (low quality) cotton ( Gossypium hirsutum ). Cotton served as the sole chemical and physical substrate for microbial population. Removal rapidly achieved without formation nitrite. (cellulose)-dependent denitrification affected by changes temperature: rates at 14°C were approximately half observed 30°C. The entirely consumed process. In a fresh reactor, colonization bacteria appears to be rate limiting factor nitrate.
