Rhodovulum sulfidophilum was grown in settled undiluted and nonsterilized sardine processing wastewater (SPW). The aims were to evaluate the effects of inoculum size media on biomass production with simultaneous reduction chemical oxygen demand (COD).Three levels (10, 20 30% v/v) developed glutamate-malate (GMM) or SPW compared. highest (4.8 g l-1) obtained after 96-h culture 20% (v/v) size, but COD (85%) 120-h a GMM. In cultures 79-83%.Inoculum GMM supported good growth Rv. subsequent COD. A conceptual model proposed for treatment utilization SPW.
