Design of Experimental Lab Scale Vertical Mass Flow Type Bioreactor for Bioethanol Production by Co-Culture Strategy from Cassava Waste

Due to a surge in demand and cost, there is requirement for alternative energy sources by devising strategies the efficient production of biofuels. Immobilized microbial systems conversion biomass fuels have become progressively important. Cassava (Manihot esculentum) processing waste, massive byproduct starch utilized this work bioethanol production. This study was an attempt design develop experimental lab-scale Vertical Mass-Flow type Bioreactor (VMFB) demarcated into aerobic anaerobic zones produce bioethanol. The upper zone meant saccharification lower fermentation, technique called Simultaneous Saccharification Fermentation (SSF). feasibility co-immobilizing strains (A. awamori D. bruxellensis) fermentation (Z. mobilis) through SSF from cassava agro-waste were tested. Polyurethane foam used reaction calcium-alginate beads immobilized microorganisms employed as carriers immobilization. main objective understand usability agricultural especially waste raw material production, using technology concentration 8 % w/w ethanol obtained.
