The bacteria were isolated from a straw, white ant, rotten wood and mold. The Vanillic acid was degraded by the bacteria from white ant or rotten wood in an incubator packed porous sillica with aeration. By commercial bacteria (Pseudomonas Aeruginosa) the various conditions were tested to be found the effective degradation. The main product was C0_2. It was measured by the sorption in Ba(OH)_2 solution. The other products were analysed by the HPLC and the gas-chromatography with FID. It was shown that the selected bacteria in the field and the commercial ones degraded the vanillic acid so quickly. The vanillic acid were degraded to C0_2 through protocatechuic acid with a rich aeration or through guaiacol with not so much one. The aerob and anaerob in the coexistence effectively degraded vanillic acid with and without the aeration alternately. From these results the importance of aeration was sertified for the biodegradation of Vanillic acid.
