Types And Characteristics Of Yeasts: An Note On Yeasts

Yeasts are unicellular organisms 3–4 µm although some yeasts can grow to 40 µm in size. Most yeasts reproduce asexually by mitosis, and by the asymmetric division process known as budding.

Yeasts, can be differentiated with moulds. By fermentation, yeast changes carbohydrates to carbon dioxide and alcohols It’s an important organism in modern cell biology research, and is the most researched microorganisms.

Yeasts are chemoorganotrophs, meaning they use organic compounds as a source of energy and do not require sunlight to grow.. Yeast species either require oxygen for aerobic cellular respiration. Yeasts grow best in a neutral or slightly acidic pH environment.

Temperature range in which yeasts grow best. E.g.: Candida slooffi at 28 to 45 °C (82 to 113 °F). The cells can survive freezing under conditions. Yeasts generally are grown in the laboratory on solid growth or in liquid broths..

Although harmless, it can give pickled vegetables a bad flavour and must be removed regularly during fermentation

Ecology

Yeasts are very common in the environment, and are often occurring yeasts on the skins of fruits and berries (such as grapes, apples, or peaches), and exits from plants (such as plant saps or cacti). Some yeasts are found in the soil and insects. The ecological function and biodiversity of yeasts are unknown compared to other] Yeasts have been found living in between people's toes. Yeasts are also present in the gut of mammals and some iReproduction
