Pichia is a genus of yeast that is commonly found in various environments, including soil, plants, and the surfaces of fruits. These microorganisms are known for their ability to ferment sugars and produce alcohol, making them useful in the food and beverage industry. Some species of Pichia are also employed in biotechnology for the production of proteins and enzymes. Certain Pichia species, such as Pichia pastoris, are particularly valued for their capacity to express recombinant proteins. This makes them important tools in research and pharmaceutical development. Their ability to grow rapidly and utilize a variety of carbon sources enhances their utility in industrial applications.
