Abstract This study focused on the utilization of medium-density fiberboard (MDF) effluent as a culture medium for Pseudomonas putida for reduction of volatile organic compounds (VOC) in pinewood. P. putida was successfully cultivated in the residual
... d in the residual carbohydrate-rich effluent after purification by centrifugation, 30 kDa membrane filtration and recovery of bioactive compounds via adsorption onto polyvinyl polypyrrolidone (PVPP). Besides monosaccharides, P. putida can metabolize glycerol, acetate, succinate, and citrate present in MDF effluent without addition of other nutrients. P. putida cultures applied to pinewood Journal Pre-proof J o u r n a l P r e -p r o o f reduced emissions of α-pinene and Δ3-carene by 80% and 50%, respectively, and β-pinene and α-terpinolene were reduced by 100% within 4 days. The valorization of industrial process effluents for VOC reduction could assist the wood processing industry in sustainably lowering VOC emissions of their products.
