Abstract:
1. Yeast comprising: a cell wall including β-glucan and mannan at a low content of the mannan to an extent that the β-glucan is exposed on a surface of a cell of the yeast, wherein the yeast has an immunopotentiating capability, and is capable of growing in an uracil-containing YPD liquid medium having osmotic pressure of 300 mOsm, wherein, when a pre-culture of the yeast grown in an uracil-containing YPDS liquid medium is added to the uracil-containing YPD liquid medium so that OD the uracil-containing YPD liquid medium comprises 1% by mass of yeast extract, 2% by mass of peptone, 2% by mass of glucose, and 6×10 the uracil-containing YPDS liquid medium comprises 1% by mass of yeast extract, 2% by mass of peptone, 2% by mass of glucose, 5.5% by mass (0.3 mol/L) of sorbitol, and 6×10 wherein the yeast is in biologically pure culture, the yeast is not recombinantly modified, the yeast is mutated the chromosomes of the yeast have one or more mutations compared with the chromosomes of the the yeast is
