Abstract
A new cloning system is described capable of expressing genetic material derived from recombinant DNA material, which comprises a yeast of the genus Kluyveromyces as a host. Suitable vectors are e.g. vectors containing autonomously replicating sequences (ARS) and vectors containing homologous Kluyveromyces DNA acting as a site for recombination with the host chromosome. New and preferred vectors are those containing ARS sequences originating from Kluyveromyces (KARS vectors). The genetically engineered new strains of Kluyveromyces produce, inter alia, lactase and chymosin.
