Reaction Conditions:
with laccase of Pleurotus ostreatus MTCC-1801;2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt in 1,4-dioxane at 20; pH=4.5;Enzymatic reaction;
Steps:
Bioconversions in the Presence of ABTS
General procedure: The biotransformation of toluene to benzaldehyde [32-34] was done in 15mLof 100mM sodium acetate buffer pH 4.5 containing 20mM toluene in dioxane,0.1mM ABTS, and 500 mL of twice-diluted crude laccase (activity of concentratedlaccase was 1.91 IU=mL) kept in a 100-mL conical flask, which was stirred vigorouslyfor 60 min (completion of the reaction was confirmed by the UV=vis spectrophotometer(Hitachi, Japan, model U-2900). The reaction solution was extractedthree times with 40mL of ethyl acetate, and 20 mL of the n-ethyl acetate extractwas injected in Waters HPLC model 600E using spherisorb C18 5 UV, 4.5250mmmm column. The mobile phase was methanol at the flow rate of 0.5mL=min. Thedetection was made using Waters UV detector model 2487 at k254 nm.
