The present application relates to a kind of illumination culture methods for improving chlorella pyrenoidosa biomass, the illumination culture method includes the following steps: chlorella pyrenoidosa stock solution is inoculated in sterile liquid medium, and chlorella pyrenoidosa is illuminated using the composite spectrum of white light and red light.The present application develops a kind of culture method for chlorella pyrenoidosa, i.e.chlorella pyrenoidosa is illuminated using the composite spectrum of white light and red light, the culture method is simple to operate, easy to implement, the method can significantly improve the growth rate and biomass accumulation of chlorella pyrenoidosa, realize the high-quality large-scale production of chlorella pyrenoidosa;It can also reduce the production energy consumption per unit biomass, solves the technical problem that yield increase and consumption reduction are difficult to consider in microalgae culture.

This invention relates to a Chlorella mutant strain that is easily separated by sedimentation and cell wall disruption, and its uses, in the fields of biology and bioengineering. The Chlorella is... Chlorella pyrenoidosa GA, deposited on March 23, 2026 at the China Center for Type Culture Collection (CCTCC), accession number CCTCC NO: M2026500. This Chlorella mutant strain showed no difference in growth compared to the wild type under all culture conditions, but exhibited a significantly increased protein accumulation. Furthermore, the mutant cells settled more easily, with significantly higher natural sedimentation and centrifugation efficiencies under the same treatment conditions compared to the wild-type strain. Cell disruption was also significantly easier, facilitating digestion and absorption by predators. The mutant strain described in this invention has broad application prospects in the production of Chlorella-related products and aquaculture.
