Management and optimisation of the AWRI Wine Microorganism Culture Collection



To provide a characterised, properly maintained and resourced wine microorganism collection for use by researchers and the wine sector.


The AWRI Wine Microorganism Culture Collection contains more than 10,000 yeast and bacterial strains including yeast genome deletion libraries, proprietary strains, and natural isolates from Australian wineries. The collection is a largely untapped resource of microbial diversity which, if properly characterised, has the potential to greatly enhance microbial strain development projects.

Ongoing use of the culture collection is expected for future Wine Australia-funded projects, which will lead to the generation and/or isolation of novel yeast and bacteria.

Research approach

Efficient use of the collection will require a reorganisation of storage facilities (including the off-site duplicate collection), and an update of the existing collection database into a format that is amenable to high throughput screening and characterisation. In addition, quality control of new depositions and existing strains within the collection will be required on an ongoing basis, and technological advances may provide opportunities to improve existing quality control regimes. Once the collection has been organised for high throughput screening, large scale genotyping and phenotyping will be feasible.

Sector benefits

New or enhanced yeast and bacterial germplasm are available to the sector to enhance winemaking processes and realise performance and economic gains, through improved fermentation efficiency and differentiation of wine products/styles.
