Abstract
The biodegradability of azo acid dyes by continuous cultivation of Pseudomonas cepacia 13NA, a bacterium able to assimilate azo dyes, was investigated as a means of improving the results of conventional biological treatments for the clarification of the waste dye liquor. It was found that all the acid dyes used were removed in high efficiencies compared with the conventional biological treatments. Multi‐stage continuous cultivation in the poor nutrient conditions used proved to be particularly effective for acid dyes that otherwise would be difficult to degrade.Keywords
