Ｌ－乳酸資化性を有する生物、およびそれを利用した資源循環方法

Japanese Patent JP7431426

B2

The present disclosure provides a system for culturing animal cells by using, as a source of nutrient, components derived from a living organism such as algae, and for reutilizing a waste culture liquid obtained therefrom.　The present disclosure provides a living organism or a cultured cell, which has undergone a modification. Said modification includes providing or enhancing the ability to utilize L-lactic acid in the living organism or the cultured cell. The present disclosure also provides a method for culturing, in recycling-oriented manner, at least two types of cells, which are cell X and cell Y, the method comprising: a step (a) for providing components excreted from the cell X to the cell Y; a step (b) for providing components originating from the cell Y to the cell X; a step (c) for culturing the cell X and the cell Y; and, as necessary, a step (d) for repeating steps (a)-(c). At least one of the components excreted from the cell X is a component that can be utilized by the cell Y. At least one of the components originating from the cell Y is a nutritional component for the cell X.
