Klyveromyces lactis

Traditional and well-established yeast species are Saccharomyces cerevisiae, Hansenula polymorpha, Klyveromyces lactis, Pichia pastoris and Schizosaccharomyces pombe. With every year that passes they are increasingly being used in industrial and pharmaceutical enzyme production on a large scale. Many further yeasts present interesting features (e.g. Arxula adeninivorans and Yarrowia lipolytica), but are not that widely used. 

Genes for pyruvate decarboxylases have been isolated from yeasts and fungi such as Saccharomyces cerevisiae [86-90], Hanseniaspora uvarum [91], Klyveromyces marxianus [92], Klyveromyces lactis [93], Neurospora crassa [94], Aspergillus parasiticus [95], plants, like maize (Zea maize) [96,97], rice (Oryza sativa) [98], tomato (Lycopersicon esculentum) [99,100], pea (Pisum sativum) [101], and tobacco (Nicotiana tabacum) [102] and from the bacterium Zymomonas mobilis [103-106].
