Eco-friendly degradative decolourisation and detoxification of azo dye Amido Black 10B by Bacillus sp. strain AK1

Bioremediation of Textile Azo Dyes Amido Black 10B, Reactive Black 5, Reactive Blue 160 by <i>Lentinus squarrosulus</i> AF5 and Assessment of Toxicity of the Degraded Metabolites

“…As the reaction continued, the intermediate products formed in the initial reaction stage possibly undergo further degradation, leading to the formation of other components. This denotes the dyes presumably undergoing catabolism and similar observation denoting putative catabolites had earlier been reported consisting of phenoloics and aromatic derivatives [29].…”

“…at 200 -400 nm and 400 -800 nm, the levels of dye decreases steadily with increasing time intervals due to the progressive decoloration and catabolism of the dye. Similar observations have indicated the gradual decrease of the absorbance peak of AB10B at 618 nm and decolourization of AB10B upon degradation, within a few hours in parallel to the formation of pink color [29] [30] [31].…”

“…It is an acidic diazo dye with strong photo-and thermal stability. This dye is well known to cause irritation to the skin, eyes, and respiratory system in humans [29] [30].…”
