From: Cultivation of algal biofilm using different lignocellulosic materials as carriers
Crude proteins and carbohydrate production of the biofilm with different materials as carriers and the suspended culture (mean ± SD). a Crude proteins and carbohydrate production calculated as dry weight per growth surface area. b Crude proteins and carbohydrate productivity calculated as dry weight per growth surface area per unit of time. c Crude proteins and carbohydrate production calculated as dry weight per carrier dry weight. d Crude proteins and carbohydrate productivity calculated as dry weight per carrier dry weight per unit of time. *Biofilm growth for 20 days, **suspended culture
