Why it’s important
Fungal genomes are rarely well characterized in public databases. Other than highly relevant model organisms like Saccharomyces cerevisiae, most available fungal genomes are highly fragmented, which presents difficulties for further genomic analyses. In the case of H. roseonigra (ATCC 20624), no member of the Hyphozyma genus has ever had its full genome sequence published. Due to the lack of public data on Hyphozyma, research on H. roseonigra is particularly limited, which is detrimental as it is the only reported strain capable of degrading sclareol to sclareol glycol.1
Sclareol glycol is a precursor of ambroxide, which is a key substitute for ambergris. Ambergris is a highly valuable and increasingly scarce fixative that prolongs the longevity of the aroma in a perfume. This fixative, however, is produced in the digestive system of certain whales and is no longer legal to trade in many countries. In an effort to protect endangered whales, there has been a shift in the fragrance industry to rely on ambroxide, a more environmentally conscious substitute.
Currently, Cryptococcus albidus is often used in the process to create ambroxide, though it cannot directly produce the precursor for ambroxide.2 Other synthetic methods to produce ambroxide or (-)-ambrox involve the use of specific plants that produce diterpenoids, though these are only created in small mixtures of other natural products.3 In contrast, H. roseonigra, shows great promise in that it can condense the production process and directly generate the precursor molecule under more laboratory-friendly conditions.
What’s the solution?
With the publication of the H. roseonigra (ATCC 20624) full genome sequence to the ATCC Genome Portal, the first step has been made to better understand members of the Hyphozyma genus and to renewing research into H. roseonigra and its prospective role in the fragrance industry.
How we can help
As part of our Enhanced Authentication Initiative, ATCC will continue to sequence and assemble genomes of organisms from our repository, paying special attention to those that have never been previously published on public databases. If you know of any such organisms that you would like for ATCC to focus our efforts into publishing on the ATCC Genome Portal send them to us.

Authentication and sequencing tools
Reproducible research starts with credible biological materials. That’s why ATCC has made a commitment to advance authentication in life science research. Through our Enhanced Authentication Initiative, we are enriching the characterization of our biological collections with reference-quality whole-genome sequencing data and making that data available to everyone.More
