: Sunset yellow is one of the dyes used in food and other allied industries having yellow to orange red color existing as
an environmental contaminant. It could impair hepatic function, and show acute toxicity to leucocytes, growth retardation etc.
Prolonged oral administration increases the liver glutathione content as well as induces of hepatotoxicity, genotoxicity, anorexia
and decrease in body weights, hair loss, ulcerated skin rashes etc. An effort was done to biomineralization using an adapted
alkaliphile Pseudomoas DL7 isolated from Lonar Lake(MS) Buldana .600mg/LSunset Yellow FCF was found completely
degraded within 48 hrs. 4-aminonaphthalene-5, 6 diol, 1-sulfonic acid, 4-aminonaphthalene-1-sulfonic acid, catechol were
confirmed as a catabolites by GCMS. pH 9.00 was found optimum for biomineralization. Enzyme induction study showed the
experimental bacteria actively plays important role in biomineralization
