Abstract
AbstractThe composition of the product of algal culture in the liquid phase of slurry has been examined. The material consists of cells of the cultured alga (Chlorella vulgaris) together with those of the endogenous microbial community, and contains approximately 42% true protein, 23% carbohydrate, 16% lipid and 9% nucleic acid. The protein is deficient in the sulphur amino acids but rich in lysine. The latter feature appears to be related to the presence of hexanoic acid in slurry. The endogenous microorganisms do not make a significant direct contribution to the composition of material harvested after algal culture. Light and temperature have only slight effects upon composition of the harvested material.
