Evaluation of the tolerance and biotransformation of ferulic acid by Klebsiella pneumoniae TD 4.7.

ABSTRACT: Derived compounds from lignin have been used as substrates for chemical and biological processes for obtainment bioproducts. The ferulic acid is a lignocellulosic biomass whose biotransformation in flavors compounds was described. The objective of this study was the bioconversion of ferulic acid to 4-vinylguaiacol by Klebsiella pneumoniae TD 4.7. The biotransformation of commercial ferulic acid into 4-vinylguaiacol in a semi synthetic liquid medium containing the ferulic acid at an initial concentration of 300 mg L^-1 reached 32.4%. The ferulic acid obtained from alkaline hydrolysis of the sugar cane bagasse at 300 mg L^-1 allowed the yield of 1.3 mmol L^-1 of 4-vinylguaiacol, corresponding to 81.7% of the ferulic acid content. The data indicated that the bact
