Kluyveromyces lactis: Kluyveromyces lactis(formerly Saccharomyces lactis) is a yeast which has the ability to assimilate lactose and convert it into lactic acid. Kluyveromyces lactis and other organisms i.e., Aspergillus niger var awamori and Escherichia coli K12 are grown in fermenters to produce chymosin (rennet) on a commercial scale; this rennet, which replaces the conventional form obtained from slaughtered animals, is now widely used in cheese production. Yeasts and fungi are ideal organisms for comparative genomic studies in eukaryotes because of their small and compact genomes and because they include a number of species such as Neurospora crassa, S. cerevisiae and Schizosaccharomyces pombe, that have been, and continue to be, used extensively in genetic studies. However, the divergence between these three species is ancient (estimated to be at least 300million years old) and the organization of their genomes is quite different. The diversity of the hemiascomycetes, a group of ascomycetes that contains most of the known yeast species was first explored in 2000.
