ResumoABSTRACT Chemical characterization of blanching effluent and bioconversion by Hansenula anamola was performed. The effluent contained 27,000 mg/L BOD and 31,000 mg/L total solids including 49.5% starch and 23.6% protein (dry basis). A high biochemical oxygen demand (BOD): chemical oxygen demand (COD) ratio (0.95) indicated a waste easily and completely degradable, with nitrogen and phosphorus levels above those necessary for unimpeded microbial growth. Batch fermentations of raw effluent produced 12g dry cells/L, containing 53% protein, with a corresponding 84% reduction in BOD. Great Northern bean blanching effluent was demonstrated to be a suitable growth medium for H. anomala .
