Defatted Chlorella biomass as a renewable carbon source for polyhydroxyalkanoates and carotenoids co-production

Defatted Chlorella biomass was investigated as an unconventional and promising carbon source for the co-production of polyhydroxyalkanoates and cartenoids via batch cultivation of Paracoccus sp. LL1. 10% (w/v) of algal biomass was subjected to acid hydrolysis using different concentrations (0.1, 0.2...

Description
Summary:Defatted Chlorella biomass was investigated as an unconventional and promising carbon source for the co-production of polyhydroxyalkanoates and cartenoids via batch cultivation of Paracoccus sp. LL1. 10% (w/v) of algal biomass was subjected to acid hydrolysis using different concentrations (0.1, 0.2, 0.3, and 0.5 N) of either sulfuric or hydrochloric acid to yield fermentable sugars. Regardless of the acid type, reducing sugar content significantly increased with an increasing acid concentration, reaching a maximum yield of 52 and 46 g/L respectively for hydrochloric and sulfuric acid catalyzed hydrolysis at the highest acid concentrations (p
