Toxicity (antibacterial effect) of untreated and treated (decolorized) dyes on a soil bacterium, Pseudomonas aeruginosa was determined. Low cost and easily available two agricultural residues (cotton stalk and apricot seed) as biosorbents were used to remove Astrazone Black and Astrazone Yellow from aqueous solution. The removal of these dyes with agricultural wastes reduced the toxic effect on P. aeruginosa. This reduction in toxic effect is important both in respect of environmental biotechnology and waste detoxification. This study showed that these agricultural byproducts can be used for decolorization and detoxification of dyes.
