Page "Yeast" Paragraph 9

Yeasts are very common in the environment, and are often isolated from sugar-rich material.

Examples include naturally occurring yeasts on the skins of fruits and berries ( such as grapes, apples or peaches ), and exudates from plants ( such as plant saps or cacti ).

Some yeasts are found in association with soil and insects.

The ecological function and biodiversity of yeasts are relatively unknown compared to those of other microorganisms.

Yeasts, including Candida albicans, Rhodotorula rubra, Torulopsis and Trichosporon cutaneum, have been found living in between people's toes as part of their skin flora.

Yeasts are also present in the gut flora of mammals and some insects and even deep-sea environments host an array of yeasts.
