Abstract:

Melamine formaldehyde resin (MFR) has stable aromatic molecular structures used as retanning agent in leather industry. The bacterial strains Klebsiella pneumoniae strain CSMB6 and Enterobacter cloacae strain CSMB2 as consortium was able to degrade MFR in a microaerobic reactor under optimized conditions. About 83% degradation was obtained with the residual COD concentration of 30 mg/L at 48h of incubation along with the biomass production of 165 mg/L as dry cells. Intermediate metabolites detected by GCMS, indicates the presence of formic acid, methyl butyl alcohol, Methoxymethyl formate and 3-Mercapto-3-methyl butyl formate. The consortium was able to degrade both melamine and formaldehyde simultaneously utilizing them as sole carbon and energy.
