The genus has just one described species, Y. lipolytica, and is commonly known by its asexual name Candida lipolytica. The species is widely distributed in name and often found in marine environments as well as elsewhere. The species has unique metabolic characteristics and can grow on hydrocarbons as well as produce lipases and proteases. Y. lipolytica is a common spoilage organism of fatty and protein rich foods such as cheeses, sausages and refrigerated meat products. The species is also considered to be an opportunistic human pathogen. Y. lipolytica is also widely known for production of the acidulant citric acid and is used industrially for this process. Noteworthy in terms of bioenergy, Y. lipolytica can produce citric acid from glycerol, a by-product of biodiesel production from vegetable oils.
