Biotransformation of Ferulic Acid to Vanillin by Locally Isolated Bacterial Cultures

Abstract

The biotransformation of ferulic acid to vanillin was

carried out using locally isolated bacterial cultures from

manure, paddy straw and garbage samples which include

<i>Pseudomonas </i>sp. <i>Pseudomonas </i>sp. was enriched with the

ferulic acid thrice and subsequently named as EF₁, EF₂ and

EF₃• EF₃ produced maximum vanillin (850 <img src='/image/spc_char/micro.gif' border=0>g/100mg culture),

followed by EF₂ (842 <img src='/image/spc_char/micro.gif' border=0>g/100mg culture), manure isolate

MAMWR (B) (598 <img src='/image/spc_char/micro.gif' border=0>g/100mgculture), EF₁ (474 <img src='/image/spc_char/micro.gif' border=0>g/100mg

culture) and <i>Pseudomonas </i>sp. (230 <img src='/image/spc_char/micro.gif' border=0>g/100mg culture).

Garbage isolate GRMWSR (B) produced very insignificant

amount (1.13 <img src='/image/spc_char/micro.gif' border=0>g/100mgculture) of vanillin.
