Antimicrobial activity of n-butyl lactate obtained via enzymatic esterification of lactic acid with n-butanol in supercritical trifluoromethane.

Highlights: [•] Lipase-catalyzed esterification of n-butyl lactate in different SCFs was performed. [•] Direct esterification catalyzed by immobilized lipase B from Candida antarctica. [•] Optimal reaction conditions in SC CHF3 (pressure and temperature) were determined. [•] The antimicrobial activity of n-butyl lactate was detected. [ABSTRACT FROM AUTHOR]
