Abstract

An industrial process for the conversion of bread waste to a substrate for the red microalga G. sulphuraria in order to produce Nanoglycogen was designed. It was aimed to investigate if bread waste can compete with glycerol as a substrate for the G. sulphuraria. The influence of the variables reaction time, enzyme concentration and temperature on the hydrolysis process were investigated for economically optimal process conditions. The optimum conditions found are T = 20 oC, t = 24 hr and enzyme concentration = 0.8 g/kg. This resulted in a glucose solution of 47.8 g/L with an estimated price of € 4.83 per kg of glucose, which is 43 times higher than the price of glycerol. It this IP it is concluded that bread waste cannot compete with glycerol as a substrate for the G. sulphuraria in the production of Nanoglycogen
