Is yeast a bacteria?

Although yeast are single-celled organisms, they possess a cellular organization similar to that of higher organisms, including humans. Specifically, their genetic content is contained within a nucleus. read more

Unlike bacteria, no known yeast species grow only anaerobically (obligate anaerobes). Most yeasts grow best in a neutral or slightly acidic pH environment. read more

You are definately wrong by saying yeast is a bacteria, that distinction is very clearly made :) Bacteria are protozoa, very primitive cells and they don't have any internal compartments. Yeast to the contrary is a very simple eukaryote (we are eukaryote too) and has subcellular compartmentalizations (organelles). read more

Bacteria and Yeast are not related in any genetic sense. Yeast, by and large, eat sugar and produce alcohol and various esters and phenols (and CO2). To most brewers (and vintners), though, the only yeast of any consequence is Saccharomyces, and any other microbe is to be avoided at all costs. read more

Yeast are classified as fungi. They are unicellular eukaryotes which means that they are single celled organisms that consist of membrane-bound nuclei and other organelles. Bacteria on the other hand are prokaryotes which implies that they do not contain a membrane-bound nucleus or other organelles. read more

Yeast to the contrary is a very simple eukaryote (we are eukaryote too) and has subcellular compartmentalizations (organelles). It is interesting to understand why the yeast cells are not pathogenic, while the hyphal cells are. read more
