Nineteen bacterial strains able to degrade and metabolize formaldehyde as a sole carbon source were isolated from soil and wastewater of a formaldehyde production factory. The samples were cultured in complex and mineral salts media containing 370 mg formaldehyde/l. The bacterial strains were identified to be Pseudomonas pseudoalcaligenesP. aeruginosaP. testosteroniP. putida, and Methylobacterium extorquens. After adaptation of these microorganisms to high concentrations of formaldehyde; two isolated strains of M. extorquens (strains ESS and PSS) and four strains of P. pseudoalcaligenes (strains LSW, SSW, NSW and OSS) degraded 1850 mg formaldehyde/l, where as P. pseudoalcaligenes strain OSS completely consumed 3700 mg of formaldehyde/l after 24 h and degraded 70% of 5920 mg of formaldehyde/l after 72 h.
