Characterization of selected microbial species for bioflocculant producing potential and comparison with traditional flocculants in industrial waste water treatment
… cancerogenicity and neurotoxiciy. Consequently, bioflocculants appear to be an attractive alternative to synthetic flocculants because they are non toxic, eco-friendly and able to flocculate at a low concentration dosage. In this study, the production of a bioflocculants from Ochrobactrum oryzae …
