The sugar concentration of the high-sugar medium is the concentration of glucose.

In high-sugar medium, the concentration of glucose is generally 4.5g/L. This high concentration of sugar can provide cells with sufficient energy and maintain intracellular osmotic pressure, which is beneficial to cell growth and reproduction.

Different types of cells have different requirements for sugar concentration. Therefore, in practical applications, it is necessary to select a suitable high-sugar medium according to the needs of the cells.
