Comparative Analysis of Authenticated Genomic and Phenotypic Data for Yarrowia lipolytica Reference Strains
46th Symposium on Biomaterials, Fuels and Chemicals (SBFC)
Alexandria, Virginia, United States
April 28, 2024Abstract
Yarrowia lipolytica stands as a pivotal microbial platform in the realm of bioindustrial applications. This presentation delves into a comparative analysis encompassing genomic and phenotypic data from over 30 haploid and diploid strains of Y. lipolytica within the ATCC reference collection. Employing long-read (Oxford Nanopore) and short-read (Illumina) sequencing technologies, we pursued whole-genome sequencing and de novo hybrid assembly for each strain, all conducted under ISO 9000 quality standards at ATCC.
Phylogenetic scrutiny revealed five distinct sub-clades among Y. lipolytica reference strains, unveiling conserved alleles within shared metabolic pathways. Subsequently, representative strains from each sub-clade underwent comprehensive phenotypic profiling on the Biolog Omnilog platform. Discrepancies in metabolic responsiveness to diverse growth conditions correlated with allelic distinctions within each subclade. This multidimensional approach identifies strains boasting optimal traits for augmented biofuel and biomaterials synthesis.
This presentation not only provides an overview of foundational reference data, accessible through the ATCC Genome Portal (https://genomes.atcc.org), but also imparts key insights facilitating future genetic engineering endeavors. By optimizing Y. lipolytica strains, our study contributes to the sustainable evolution of bioindustrial applications, propelling advancements in biofuel and biomaterials production.
