Towards a genome-scale metabolic model for the Kluyveromyces lactis yeast

The interest in Kluyveromyces lactis (K. lactis) has begun in academia due to its ability to metabolize the betaglycoside (1). Since then, this yeast has been considered a model organism for studies in genetics and physiology (2). This yeast had its genome sequenced back in 2004 (3) and recently we have published a full metabolic re-annotation of its genome (4). This re-annotation can be used, among other appli...

iOD962 - the first genome-scale metabolic model of Kluyveromyces lactis

The genome-scale metabolic model of Kluyveromyces lactis was reconstructed from its genome annotation. The result was the partially compartmentalized (5 compartments) iOD962 metabolic model composed of 2038 reactions and 1561 metabolites. Previous chemostate experiments were used to adjust the maintenance ATP parameter, and the model proved valuable when predicting the biomass, oxygen and carbon dioxide yields....

Genome-wide metabolic (re-) annotation of Kluyveromyces lactis

Even before having its genome sequence published in 2004, Kluyveromyces lactis had long been considered a model organism for studies in genetics and physiology. Research on Kluyveromyces lactis is quite advanced and this yeast species is one of the few with which it is possible to perform formal genetic analysis. Nevertheless, until now, no complete metabolic functional annotation has been performed to the prot...

Multiple gene disruption and marker rescue in the yeast Kluyveromyces marxianus

Application of the Cre-loxP system for multiple gene disruption in the yeast kl...

The yeast Kluyveromyces marxianus presents several interesting features that make this species a promising industrial yeast for the production of several compounds. In order to take full advantage of this yeast and its particular properties, proper tools for gene disruption and metabolic engineering are needed. The Cre-loxP system is a very versatile tool that allows for gene marker rescue, resulting in mutant ...
