The inductive effect of lactose,S-methyl-thio-g-galactopyranoside, (TMG) and glucose on B galactosidase synthesis in Kluyveromyces lactis has been \_ .~ ---\_~ studied. Whereas TMG gave a five fold stimulation of the rate of @galactosidase synthesis, lactose only gave a small stimulation. Glucose c

After extraction from whole cells, and purification by gel filtration, the chemical composition and molecular mass estimation of the cell-wall phosphopeptidomannan (PPM) showed no significant difference respectively between flocculent, weakly, very weakly and non-flocculent Kluyveromyces lactis yeas
By employing pulsed field gel electrophoresis we find that slow growing strains of Kluyveromyces lactis have only 43%-55% of the wild-type level of ribosomal DNA (rDNA) repeats. When subjected to prolonged vegetative growth these strains can increase both the number of rDNA repeats and their growth
