Abstract

Tyrosinase and bovine serum albumin were co-crystallized by saturated ammonium sulfate solution(65%) and 20% polyethylene glycol ( PEG) 6000 and n-propanol as co-solvents .The obtained crystals were cross linked by glutaraldehyde solution(1% v/v).Polyethylene glycol 6000 was found to be better co-solvent than n-propanol. The developed biocatalyst could be recycled 6 times without further loss of tyrosinase activity. No loss of activity of cross linked tyrosinase -bovine serum albumin crystals was observed upon storage of the developed CLECs at refrigerator for six months.
