[BMIM][PF6] gave about 97% and 84% activities of that obtained in Tris-HCl
aqueous buffer medium for forward and reverse enzyme catalyzed reactions, respectively.
Phenylalanine ammonia lyase forward and reverse activities of Rhodotorula
glutinis were successfully demonstrated in ionic liquids. Experimental conditions were
standardized for optimal activity of PAL in different ILs. Maximal enzyme activity was
obtained with [BMIM][PF6]; the yield of PAL forward and reverse reactions was 83%
and 59%, respectively.
