水溶性酵母蛋白胨，呈現細緻的米色粉末，由初級培養的酵母 Saccharomyces cerevisiae 經過嚴格控制的酵素溶解製成。含有高蛋白質，以易吸收的預消化形式（胜肽和胺基酸）提供營養，並含有可溶性維生素、礦物質及其他生長因子。

Yeast Peptone SF503 is a water-soluble fine beige powder, produced by controlled enzymatic solubilization of primary growth yeast of the genus Saccharomyces cerevisiae. It contains a high level of protein, in readily and easily absorbable pre-digested forms such as peptides and amino acids, soluble vitamins, minerals, and other growth factors.

成分 Composition: Yeast peptone, monosodium L-glutamate, and I+G, for use in culture media.
