Kluyveromyces aestuarii was found in sediments from 7 of 8 mangroves in Rio de Janeiro; and absent only at one site with heavy plastic bag pollution. Its presence suggests influence in other habitats from a mangrove and its absence in a mangrove suggests some non- fecal pollution or other habitat alteration.

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.

Deoxyribonucleic acid (DNA) base composition and DNA base sequence relatedness comparisons were used for species delineation in the genus Kluyveromyces. Base composition values separated the members of the genus into three groups. The groups were further subdivided by comparing base sequences by using DNAIDNA renaturation experiments. Two DNA homology groups were identified. The first group inc...

We determined the genome sequence of a thermotolerant yeast, Kluyveromyces marxianus strain DMB1, isolated from sugarcane bagasse hydrolysate, and the sequence provides further insights into the genomic differences between this strain and other reported K. marxianus strains. The genome described here is composed of 11,165,408 bases and has 4,943 protein-coding genes.

Kluyveromyces marxianus is a thermotolerant yeast that has been explored for potential use in biotechnological applications, such as production of biofuels, single-cell proteins, enzymes, and other heterologous proteins. Here, we present the high-quality draft of the 10.9-Mb genome of K. marxianus var. marxianus KCTC 17555 (= CBS 6556 = ATCC 26548).

We report the genome sequence of the dairy yeast Kluyveromyces lactis strain GG799 obtained using the Pacific Biosciences RS II platform. K. lactis strain GG799 is a common host for the expression of proteins at both laboratory and industrial scales.

Here, we present the draft genome sequence of Kluyveromyces marxianus CCT 7735 (UFV-3), including the eight chromosomes and the mitochondrial genomic sequences.

The linear dsDNA plasmids, pGKL1 (8.9 kb) and pGKL2 (13.4 kb) discovered in Kluyveromyces lactis, confer killer and immunity characteristics upon various yeast strains. We have devised an immunity assay and have been able to show the expression of an immunity phenotype in the K. lactis transformants harbouring conventional circular plasmids which contain DNA fragments of pGKL1. Using this expre...

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.
