Interfertility as basis for the delimitation of Kluyveromyces marxianus

Archives of Microbiology, 1978
Hybridization studies between strains of Kluyveromyces marxianus and the remaining species of the genus involving the use of auxotrophic mutants, are reported. K. marxianus was found to be interfertile with K. bulgaricus, K. cicerisporus, K. dobzhanskii, K. drosophilarum, K. fragilis, K. lactis, K. phaseolosporus, K. vanudenii and K. wikenii. Accepting

Iminodiacetate and Nitrilotriacetate Degradation by Kluyveromyces marxianus IMB3

Biochemical and Biophysical Research Communications, 2002
The thermotolerant yeast Kluyveromyces marxianus IMB3 was capable of utilising either iminodiacetate or nitrilotriacetate as a sole source of nitrogen for growth. Cell extracts contained iminodiacetate dehydrogenase and nitrilotriacetate monooxygenase activities, suggesting the presence in the yeast of orthologues of these bacterial enzymes.

Kluyveromyces marxianus as a host for heterologous protein synthesis

Applied Microbiology and Biotechnology, 2016
The preferentially respiring and thermotolerant yeast Kluyveromyces marxianus is an emerging host for heterologous protein synthesis, surpassing the traditional preferentially fermenting yeast Saccharomyces cerevisiae in some important aspects: K . marxianus can grow at temperatures 10 °C higher than S.

Kluyveromyces marxianus: a potential source of diacetyl reductase

World Journal of Microbiology & Biotechnology, 1994
Kluyveromyces marxianus had a higher specific activity of diacetyl reductase (EC 1.1.1.5) than all other organisms previously reported. The enzyme was NADH-dependent and irreversibly catalysed the conversion of diacetyl to acetoin with an optimum pH of 7.0. It was stable at 40°C but lost 50% of its activity at 50°C in 30 min.

Characterizing yeast promoters used in Kluyveromyces marxianus

World Journal of Microbiology and Biotechnology, 2015
Fermentation at higher temperatures can potentially reduce the cooling cost in large-scale fermentation and reduce the contamination risk. Thus, the thermotolerant yeast, Kluyveromyces marxianus, which can grow and ferment at elevated temperatures, is a promising biotechnological tool for future applications. However, the promoters used in K. marxianus

Flocculation of Kluyveromyces marxianus is induced by a temperature upshift

Yeast, 1993
AbstractAn upshift of the growth temperature from 26 to 40°C in the presence of calcium leads to the aggregation of Kluyveromyces marxianus cells and to the formation of flocs. Analysis of cell wall proteins, either by sodium dodecyl sulphate–polyacrylamide gel electrophoresis of extractable mannoproteins or by immunolocalization, revealed an ...

D-Xylose Transport by Candida succiphila and Kluyveromyces marxianus

Applied Biochemistry and Biotechnology, 2003
The kinetics and regulation of D-xylose uptake were investigated in the efficient pentose fermentor Candida succiphila, and in Kluyveromyces marxianus, which assimilate but do not ferment pentose sugars. Active high affinity (Km approximately 3.8 mM; Vmax approximately 15 nmol/[mg min]) and putative facilitated diffusion low-affinity (Km approximately ...

CHARACTERIZATION OF AN 'ENDOPOLYGALACTURONASE' OF THE YEAST KLUYVEROMYCES MARXIANUS

Journal of Food Biochemistry, 1983
Analytic isoelectric focusing showed that the ‘endopolygalacturonase’ from Kluyveromyces marxianus consists of 21 multiple enzyme components. Neither changes in cultivation conditions, enzyme substrate or reaction conditions resulted in any quantitative or qualitative differences in the enzyme patterns.

Location of the β-galactosidase of the yeast Kluyveromyces marxianus var. marxianus ATCC 10022

Antonie van Leeuwenhoek, 1996
During the growth of Kluyveromyces marxianus var. marxianus ATCC 10022 on lactose, peaks of glucose, but not beta-galactosidase activity, were detected in culture medium. Harvested and washed whole cells produced glucose and galactose from lactose, or ortho-nitro-phenol from the chromogenic substrate ortho-nitro-phenyl-beta-D-galactopyranoside (ONPG ...

Evaluation of Kluyveromyces marxianus as baker's yeast

Food Research International, 1995
Abstract Two strains of Kluyveromyces marxianus (NRRL-Y-2415 and NRRL-Y-1109) were assessed as baker's yeasts comparing them with two strains of Saccharomyces cerevisiae isolated respectively from compressed yeast and active dry yeast. Strains were tested for dough proofing activity in lean dough and rich doughs (prepared with sucrose, lactose or
