The name Chlorella is taken from the Greek, chloros, meaning green, and the Latin diminutive suffix ella, meaning small. German biochemist and siologist Otto Heinrich Warburg, awarded with the Nobel Prize in siology or Medicine in 1931 for his research on respiration, also studied tosynthesis in Chlorella. In 1961, Melvin Calvin of the University of California received the Nobel Prize in Chemistry for his research on the pathways of carbon dioxide assimilation in plants using Chlorella.Many people believe Chlorella can serve as a potential source of food and energy because its tosynthetic efficiency can reach 8%, which exceeds that of other highly efficient crops such as sugar cane.
