چکیده انگلیسی
A techno-economic analysis (TEA) was performed on glucosamine and lipid production from a marine diatom Cyclotella sp. in raceway open pond (RWP) and tubular photobioreactor (PBR) cultivation systems. Two PBR operating schemes were assessed: one to produce high lipid (HL) content, and another to produce high chitin (HC) content. In order to generate 1Â kg of glucosamine, 9700Â kg (RWP)/1050Â kg (PBR HL) freshwater, 40Â kg CO2, 0.70Â kg nitrogen, 0.18Â kg phosphorus, and 1.2Â kg silicon nutrients are required for algae cultivation with water and nutrient recovery. With a price of $1.5 for lipid as coproduct, the projected selling price of glucosamine were $35/kg, $106/kg and $82/kg for RWP, PBR HL, and PBR HC systems, respectively. Currently, these prices are not competitive with industrial shellfish-derived glucosamine, but can be reduced by technology improvements such as producing food grade lipid, increasing algal productivity or chitin content.
