Yeast grows best in a neutral to slightly acidic environment. The pH inside a yeast cell is held relatively constant at around 5.5 and as long as this can be maintained the external pH doesn't matter too much.
The ideal pH for fermentation is probably closer to 4.0. Not because of yeast's preferences but because bacterial growth is seriously inhibited at this pH.
Saccharomyces is a yeast and it isn't normally described in terms of it's pH. That said, yeast's cytoplasm is normally maintained at a pH between 5.5 and 5.75. Yeast prefers to live in a mildly acid environment and yeast growth produces a range of organic acids which lowers the pH of it's environment.

The yeast Saccharomyces cerevisiae is used for fermentation. http://en.wikipedia.org/wiki/Saccharomyces_cerevisiae
It is eukaryotic. Fungi are found in the Eukarya branch of the Tree of Life model of evolutionary biology.
Mannitol salt agar inoculated with Micrococcus luteusshowing no fermentation of mannitol (pink medium). The colonies show a yellow pigment which is characteristic of M. luteus.
Saccharomyces cerevisiae was created in 1883.
Baker's yeast has the scientific name of Saccharomyces cerevisiae. This means that the genus of baker's yeast is Saccharomyces and the species is cerevisiae.
There are 16 chromosomes in a haploid cell of saccharomyces cerevisiae.
