Transfer of DNA killer plasmids from Kluyveromyces lactis to Kluyveromyces fragilis and Candida pseudotropicalis.

Killer plasmids pGKL1 and pGKL2 of double-stranded linear DNAs were transferred from Kluyveromyces lactis to strains of Kluyveromyces fragilis and Candida pseudotropicalis. The resultant killer strains produced 17-fold and 6-fold larger amounts of killer toxin than K. lactis did, respectively. The killer toxin produced by each species appeared to be a glycoprotein.

Draft Genome Sequence of the Probiotic Yeast Kluyveromyces marxianus fragilis B0399

Here, we report the draft genome sequence of Kluyveromyces marxianus fragilis B0399, the first yeast approved as a probiotic for human consumption not belonging to the genus Saccharomyces The genome is composed of 8 chromosomes, with a total size of 11.44 Mb, including mitochondrial DNA.

Enhanced Conversion of Lactose to Glycerol by Kluyveromyces fragilis Utilizing Whey Permeate as a Substrate.

Kluyveromyces fragilis (CBS 397) is a nonhalophilic yeast which is capable of lactose utilization from whey permeate and high glycerol production under anaerobic growth conditions. However, the optimum yields of glycerol (11.6 mg/ml of whey permeate medium) obtained in this study occurred only in the presence of 1% Na(2)SO(3) as a steering agent. The use of other concentrations of Na(2)SO(3), a...
