Abstract: Many of the current industrial fermentation processes cannot use pentose as the carbon source.However, complete substrate utilization of sugars in lignocellulose is one of the prerequisites to render economic development of biofuels or bioproducts from biomass.In this study we proposed a new process for DHA production from renewable carbon sources by first using anaerobic bacteria, Clostridium tyrobutyricum to convert pentose into organic acids with butyric acid as the main product, and then using the organic acids to feed microaglae, Crypthecodinium cohnii to produce DHA.The effect of glucose and xylose on the yield of butyric acid produced by C. tyrobutyricum was investigated, separately.Cell growth of C. tyrobutyricum increased with
