[6] Chlorella vulgaris has a number of potential applications in science, such as biofuel, livestock feed, and wastewater treatment.

[3] Beginning in the 1990s, German scientists noticed the high protein content of C. vulgaris and began to consider it as a new food source.

[10] Chlorella vulgaris occurs as a symbiont in tissues of the freshwater flatworms Dalyellia viridis and Typhloplana viridata.

[11] The world annual production of the various species of Chlorella was 2000 tonnes (dry weight) in 2009, with the main producers being Germany, Japan and Taiwan.

[3] C. vulgaris is a candidate for commercial production due to its high resistance against adverse conditions and invading organisms.

In addition, the production of the various organic macromolecules of interest (proteins, lipids, starch) differ depending on the technique used to create biomass and can be therefore targeted.

[32] It is not widely incorporated in food products due to its dark green color and smell similar to that of fish.
