Biotransformation of Ferulic Acid to Vanillin by Locally Isolated Bacterial Cultures

Abstract

610-612The biotransformation of ferulic acid to vanillin was carried out using locally isolated bacterial cultures from manure, paddy straw and garbage samples which include Pseudomonas sp. Pseudomonas sp. was enriched with the ferulic acid thrice and subsequently named as EF1, EF2 and EF3• EF3 produced maximum vanillin (850 g/100mg culture), followed by EF2 (842 g/100mg culture), manure isolate MAMWR (B) (598 g/100mgculture), EF1 (474 g/100mg culture) and Pseudomonas sp. (230 g/100mg culture). Garbage isolate GRMWSR (B) produced very insignificant amount (1.13 g/100mgculture) of vanillin
