The Chlorella samples have a very broad range of biochemical compositions ranging from 6–58% lipid content. Additionally, three strains of Pseudochoricystis ellipsoidea from the DENSO COROPORATION grown in photobioreactors, two strains of Chlorogloeopsis fritschii from the Plymouth Marine Laboratory and one sample each of P. ellipsoidea grown in outdoor raceway ponds in Japan (DENSO COROPORATION, Japan). One was harvested by centrifuge; the other was harvested by chemical flocculation. The average composition of all algae lies at 30% protein, 30% carbohydrates and 26% lipids. Each analysis was carried out in duplicate, when sufficient algae mass was available for duplicate analysis, and average values are reported. The measurement error range for the protein, carbohydrate and lipid analyses, lie at 1.5, 1.3 and 0.5% respectively. Therefore, we report the single, non-duplicate values with relatively high confidence.
