Kluyveromyces lactis is a species of yeast commonly used in biotechnology and food production. It is known for its ability to ferment lactose, the sugar found in milk, making it valuable in dairy applications. This yeast can also be used to produce various enzymes and proteins, contributing to the development of biofuels and pharmaceuticals. In addition to its industrial uses, Kluyveromyces lactis serves as a model organism for scientific research. Its genetic and metabolic pathways are well-studied, allowing researchers to explore yeast biology and improve fermentation processes. This versatility makes it an important organism in both research and industry.
