Erwinia carotovora FERM P-7576,a soft-rot pathogen screened for biochemical pulping, was used to dispose of pectic wastewater discharged from orange canning factories as a pretreatment for an activated sludge process. Twelve hour bacterial pretreatment made it possible to reduce COD and total uronic acids by 10% and 84%, respectively, with supplementation of some nutrients (N, P, and K) and keeping DO constant.Enzymatic pretreatment using crude enzyme from this strain degraded almost all the pectic substances in this waste to the level of tetramers and pentamers within 24h.These pretreatment was found to provide more rapid decomposition of the chemically very resistant pectic substances than other chemical, physical, or biological methods.
