Provided is an acid-tolerant yeast cell, a method of producing an organic acid by using the yeast cell, and a method of producing the yeast cell resistant to acid.

Provided are a genetically engineered yeast cell having increased activity of SUL1, STR3, HXT7, ERR1, GRX8, MXR1, GRE1, MRK1, AAD10 or a combination thereof, compared to a parent cell, and also having acid tolerance, a method of preparing the same, and a method of producing lactate using the same.

A recombinant yeast cell having a decreased RGT1 protein activity and an increased ability to produce a glycolytic intermediate or a glycolytic intermediate-derived substance, compared to a parent cell; methods of producing the same; and methods of producing the glycolytic intermediate or the glycolytic intermediate-derived substance using the same.
