Bicultures overyielding versus nonoveryielding in FAME production exhibit notably distinct expression patterns of genes regulating synthesis and oxidation of fatty acids and other lipids. These patterns are conserved across multiple algal species. We illustrate these patterns via principal-component analysis incorporating mean log₂-fold change values in the monoculture versus biculture conditions for each algal species of 28 different Gene Ontology groups involved in lipid regulatory functions.
