Characterise your wine yeasts with our whole genome sequencing service

Yeasts, particularly Saccharomyces spp., play a fundamental role in winemaking. Our characterisation service uses whole genome sequencing to differentiate among closely related strains and to screen for relevant genes involved in the fermentative process. This will enable you to identify and select yeast strains with higher fermentation performance, such as higher ethanol and SO2 tolerance, or low acetic acid production and nitrogen requirements.

 

The image shows how the Wine industry can easily characterise their yeasts by whole-genome sequencing. The steps involved in this analysis are DNA isolation from the yeast material, library preparation, high-throughput sequencing, and bioinformatic analysis to get the annotated genome of the yeast samples.

Step 1

We isolate DNA from your yeast cultures.

Step 2

We prepare genomic libraries using the kits recommended by Illumina.

Step 3

We sequence the libraries using the Illumina NovaSeq technology.

Step 4

We analyse the high-throughput sequencing data to obtain your annotated contigs.

What you receive

icon
A species or strain identification certificate
icon
A report with a summary of the methods followed.
icon
The raw high-throughput sequencing files.

icon
The results of the bioinformatic analysis including:
  • Automatic gene annotation.
  • Average nucleotide identity between the genomes sequenced and other yeast genomes available in reference databases.
We can also carry out on-demand bioinformatic analyses, which can be applied to investigate strain relatedness or look for specific gene sets.

At no additional cost, our project specialists will be available to you after project delivery. We offer up to five 60-min sessions per project, depending on the project size.

What we need

Your yeast cultures which have been appropriately preserved (fresh, frozen, or lyophilised). Please contact us if you need assistance on how to preserve and ship your cultures.
