Preparation

Weigh 18.44g of this product, heat and dissolve in 1000ml distilled water, 121℃ autoclave for 15 minutes.


Note: 

1. It's a common option to add an appropriate amount of sugar (glucose, maltose and cellobiose each with a final concentration of 2.0 g/L; or only glucose with a final concentration of 5.0 g/L), amino acid (L-cysteine HCl 1.0g/L), vitamins and volatile fatty acids according to the use.

2. Add an appropriate amount of agar (1~2% w/w) to prepare a semi-solid or solid culture medium.


Caution:

When YCFA Medium is prepared, the solution may quickly produce a lot of foam (carbon dioxide produced by sodium bicarbonate when it meets acidic liquid), which is normal and the foam will disappear after a few minutes of resting.
