BACKGROUND Bioethanol from lignocellulosic materials is of great significance to the production of renewable fuels due to its wide sources. However, multiple inhibitors generated from pretreatments represent great challenges for its industrial-scale fermentation. Despite the complex toxicity mechanisms, lignocellulose-derived inhibitors have been reported to be related to the levels of intracel...

Abstract Kluyveromyces marxianus is a yeast that could be identified from kefir and can use broad range of substrates, such as glucose lactate, carbon sources. The lactate produced in culture substrate for K. . However, the complexity microbiota makes traits difficult to study. In this research, we focused on cultured with sole source. optimal growth released protein were determined under diffe...

Biochemical and molecular analysis was used for identification of different kefir yeasts species from Brazil, Canada and the United States of America. The sugar/ethanol-resistant activity of the yeasts was evaluated. Saccharomyces cerevisiae and Kluyveromyces marxianus had the highest growth rates, suggesting biotechnological applications possible for these strains.

An increasing interest in novel wine productions is focused on non-Saccharomyces yeasts due to their potential improving sensory profiles. Although Kluyveromyces marxianus has been originally isolated from grapes and its enzymatic activities are used oenology, rarely it as co-starter. The K. Km L2009 strain characterized here selected a co-starter both at laboratory- winery-scale fermentation. ...

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.

Kluyveromyces marxianusis the fastest-growing eukaryote on Earth and a promising non-conventional yeast for different biotechnological applications. One of these applications is production bioethanol from lignocellulosic hydrolysates at high temperature. Here, new thermotolerant strain K. marxianus(Kmx24) was isolated cooked henequen core. Its tolerance to acetic acid, one most common fermentat...
