A rapid colorimetric screening method for vanillic acid and vanillin-producing bacterial strains
Aim: To isolate a bacterial strain capable of biotransforming ferulic acid, a major component of lignin, into vanillin and vanillic acid by a rapid colorimetric screening method. Methods and Results: For the production of vanillin, a natural aroma compound, we attempted to isolate a potential strain...
