Location of the β-galactosidase of the yeast Kluyveromyces marxianus var. marxianus ATCC 10022
Antonie van Leeuwenhoek, 1996During 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 ...

Survival of Kluyveromyces marxianus with stigmasterol as subjected to freezing stress
Journal of Bioscience and Bioengineering, 2019Kluyveromyces marxianus is an aerobic yeast and is interested to be applied in many industries. This research was aimed to study the effect of the sterol alternative to ergosterol on the freezing stress of K. marxianus UBU1-11, a thermotolerant yeast. The 0-9 mgL-1 stigmasterol were added to the YM broth and applied for culturing.

Modes of lactose uptake in the yeast species Kluyveromyces marxianus
Antonie van Leeuwenhoek, 1990Twelve lactose-assimilating strains of the yeast species Kluyveromyces marxianus and its varieties marxianus, lactis and bulgaricus were studied with respect to transport mechanisms for lactose, glucose and galactose, fermentation of these sugars and the occurrence of extracellular lactose hydrolysis. The strains fell into three groups.

Karyotype and isozyme profiles do not correlate in Kluyveromyces marxianus var. marxianus
Mycological Research, 1992Diverse karyotypes were found for Kluyveromyces marxianus var. marxianus (anamorph = Candida kefyr) when analysed by pulsed-field gel electrophoresis. Two classes were discernible. One class was represented by six or seven chromosome-sized bands ranging from 1000 to 2400 kbp, the other by 9–17 bands including both smaller and larger pieces of DNA.

Adsorption of Kluyveromyces marxianus pectinase on CM-Sephadex gels
Enzyme and Microbial Technology, 1993New results are presented on the equilibria and kinetics of the ion exchange onto CM-Sephadex of polygalacturonase (pectinase) produced by the fermentation of Kluyveromyces marxianus. It is found that the equilibrium behavior follows the form of the Langmuir isotherm; the equilibrium is strongly affected by pH.

A biosynthetic pathway for hexanoic acid production in Kluyveromyces marxianus
Journal of Biotechnology, 2014Hexanoic acid can be used for diverse industrial applications and is a precursor for fine chemistry. Although some natural microorganisms have been screened and evolved to produce hexanoic acid, the construction of an engineered biosynthetic pathway for producing hexanoic acid in yeast has not been reported.

Stress response and adaptation mechanisms in Kluyveromyces marxianus
Kluyveromyces marxianus is a non-Saccharomyces yeast that has gained importance due to its great potential to be used in the food and biotechnology industries. In general, K. marxianus is a known yeast for its ability to assimilate hexoses and pentoses; even this yeast can grow in disaccharides such as sucrose and lactose and polysaccharides such as ...G, Flores-Cosío +3 more

High efficiency transformation of Kluyveromyces marxianus by a replicative plasmid
Current Genetics, 1993Kluyveromyces marxianus can be transformed with an efficiency of 10(5) transformants/microgram of DNA by a replicative plasmid using electroporation. In order to obtain this efficiency, we isolated ura- mutants cells which can be complemented by the URA3 gene from Saccharomyces cerevisiae.

Production of 2‐Phenylethyl Alcohol by Kluyveromyces marxianus
Biotechnology Progress, 1998AbstractAmong the numerous yeasts able to produce flavor compounds, several strains of Kluyveromyces species are known for the synthesis of large amounts of aromatic compounds. In particular, the accumulation of 2‐phenylethyl alcohol in liquid cultures of Kluyveromyces marxianus was observed after incubation on a semisynthetic medium at 30 °C, 125 rpm.

[Fermentations of xylose and arabinose by Kluyveromyces marxianus].
Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2018Kluyveromyces marxianus, as unconventional yeast, attracts more and more attention in the biofuel fermentation. Although this sort of yeasts can ferment pentose sugars, the fermentation capacity differs largely. Xylose and arabinose fermentation by three K. marxianus strains (K. m 9009, K. m 1911 and K.
