To decrease our dependency for the diminishing source of fossils resources, bio-based alternatives are being explored for the synthesis of commodity and high-value molecules. One example in this ecological initiative is the microbial production of the biosurfactant sophorolipids by the yeast Starmerella bombicola. Sophorolipids are surface-active m...

In the macroscopic world, ecological interactions between multiple species of fauna and flora are recognised as major role-players in the evolution of any particular species. By comparison, research on ecological interactions as a driver of evolutionary adaptation in microbial ecosystems has been neglected. The evolutionary history of the budding y...

High transformation efficiency is essential in genetic engineering for functional metabolic analysis and cell factory construction, in particular in construction of long biosynthetic pathways with multiple genes. Here, we found that free fatty acid (FFA)-overproducing strain showed higher transformation efficiency in Saccharomyces cerevisiae. We th...

Although only 6 years old, the CRISPR system has blossomed into a tool for rapid, on-demand genome engineering and gene regulation in Saccharomyces cerevisiae. In this minireview, we discuss fundamental CRISPR technologies, tools to improve the efficiency and capabilities of gene targeting, and cutting-edge techniques to explore gene editing and tr...

Despite the increasing relevance, ranging from academic research to industrial applications, only a limited number of non-conventional, oleaginous Yarrowia lipolytica strains are characterized in detail. Therefore, we analyzed three strains in regard to their metabolic and physiological properties, especially with respect to important characteristi...

Although yeasts are unicellular microorganisms that can live independently, they can also communicate with other cells, in order to adapt to the environment. Two yeast species, the budding yeast Saccharomyces cerevisiae and the fission yeast Schizosaccharomyces pombe, engage in various kinds of intraspecies cell-cell communication using peptides an...

The yeast family Pichiaceae, also known as the 'methylotrophs clade', is a relatively little studied group of yeasts despite its economic and clinical relevance. To explore the genome evolution and synteny relationships within this family, we developed the Methylotroph Gene Order Browser (MGOB, http://mgob.ucd.ie) similar to our previous gene order...

The commensal species Candida parapsilosis is an emerging human pathogen that has the ability to form biofilms. In this study, we explored the impact of the divalent cations cobalt (Co2+), copper (Cu2+), iron (Fe3+), manganese (Mn2+), nickel (Ni2+) and zinc (Zn2+) on biofilm formation of clinical isolates of C. parapsilosis with no, low and high bi...

Microorganisms have evolved to produce specific end products for many reasons, including maintaining redox balance between NAD+ and NADH. The yeast Saccharomyces cerevisiae, for example, produces ethanol as a primary end product from glucose for the regeneration of NAD+. Engineered S. cerevisiae strains have been developed to ferment lignocellulosi...

Decoding the genetic basis of lignocellulosic inhibitor tolerance in Saccharomyces cerevisiae is crucial for rational engineering of bioethanol strains with enhanced robustness. The genetic diversity of natural strains present an invaluable resource for the exploration of complex traits of industrial importance from a pan-genomic perspective to com...
