Abstract
Disclosed are modified strains of Chlorella vulgaris having a very low chlorophyll content. Also disclosed is a method for producing them. The method involves performing mutagenesis of a parental strain of Chlorella vulgaris. Furthermore, disclosed is a composition comprising algae biomass derived from the modified strains of Chlorella vulgaris and their use in food and/or cosmetics amongst other applications.

A modified strain of Chlorella vulgaris having a chlorophyll content in a range of 0.001 to 0.5 mg/g dry cell weight.
A method of producing a modified strain of Chlorella vulgaris having a chlorophyll content in a range of 0.001 to 0.5 mg/g dry cell weight, wherein the method comprises:
- a) obtaining a parental strain of Chlorella vulgaris,
- b) performing mutagenesis of the parental strain of Chlorella vulgaris,
- c) cultivating the mutated strain of Chlorella vulgaris:
- at a specific temperature, for a predefined period of time, without presence of light and in the presence of an organic carbon energy source;
- and
- d) identifying colonies of the mutated strain of Chlorella vulgaris having a phenotype different from the parental strain of Chlorella vulgaris as the modified strain of Chlorella vulgaris.
