Substrate and oxygen dependent citric acid production by Yarrowia lipolytica: Insights through transcriptome and fluxome analysis

ABSTRACT: The goal of the study is to use Next generation sequencing (RNA-seq) and 13C based flux analysis to study the underlying regulation of citric acid metabolism in mixed culture fermentation (glucose and glycerl) of Yarrowia lipolytica. We sequenced the RNA from 4 different samples in the mixed culture (glucose and glycerol) under oxygen excess and limited conditions with 2 replicates each . Transcriptional profiles showed that under oxygen limited conditions, due to deficient mitochondrial activity, citric acid is being consumed back after glycerol exhaustion eventhough glucose is present in excess. Transcriptome and fluxome profiles showed that glucose is mainly directed towards the Pentose phosphate pathway in the dual substrate fermentations.

Medium pH influences citric acid and lipid production in oleaginous yeast Yarrowia lipolytica

Project description:The goal of this study is to find out how Yarrowia lipolytica W29’s transcriptome changes in response to different pHs in certain medium, where the production of citric acid and lipid vary significantly at different pHs. The changes in transcriptome will give us insight about the mechanism of citric acid and/or lipid production are regulated. We harvested Y. lipolytica cells from bioreactor cultures from three different pHs: 2.0, 4.0 and 6.0 in triplicates. We sequenced the mRNA by Illumina HiSeq 2500 and generated an average of 20 million reads for each sample. We did not find distinct gene expression changes for the enzymes right downstream the intersection where citrate is cleaved into acetyl-CoA. Instead, from gene ontology enrichment analysis, we observed proteins with transport activities were overrepresented in gene groups that were up-regulated higher pH conditions, where citric acid secretion is favored.

Absolute expression level of Yarrowia lipolytica genes

Project description:Total RNA versus genomic DNA hybridization on custom arrays designed for all Yarrowia lipolytica genes Total RNA was collected in mid-log phase from Yarrowia lipolytica cells grown in rich medium (abbreviated CM, in house recipe). RNA was then converted to cDNA, Cy3-labeled and hybridized competitively against Cy5 labeled genomic DNA from Yarrowia lipolytica.

Expression analysis of Yarrowia lipolytica Y4184 snf1 mutant

Project description:Investigation of whole genome gene expression level changes in a Yarrowia lipolytica Y4184 snf1 mutant, compared to the Y4184U+. The Y4184 is an engineered strain to produce eicosapentaenoic acid (EPA) via expression of a M-NM-^T9 elongase/M-NM-^T8 desaturase pathway, and is derived from Yarrowia lipolytica ATCC#20362. A six chip study using total RNA recovered from three separate cultures of Yarrowia lipolytica Y4184Ura+ strains and three separate cultures of Y4184 snf1 mutant strains in which YlSNF1 gene is deleted entirely. Each chip measures the expression level of 6708 genes from Yarrowia lipolytica ATCC#20362 with fourteen 24-mer probe pairs (PM/MM) per gene, with three-fold technical redundancy.

Functional genomics for the oleaginous yeast Yarrowia lipolytica

Project description:Oleaginous yeasts are valuable systems for biosustainable production of hydrocarbon-based chemicals. Yarrowia lipolytica is one of the best characterized of these yeast with respect to genome annotation and flux analysis of metabolic processes. Nonetheless, progress is hampered by a dearth of genomewide tools enabling functional genomics. The Hermes DNA transposon was expressed to achieve saturation mutagenesis of the Y. lipolytica genome. Over 535 thousand independent insertions were identified by next-generation sequencing. Poisson analysis of insertion density classified ~22% of genes as essential. As expected, most essential genes not only have homologues in Saccharomyces cerevisiae and Schizosaccharomyces pombe, but the majority of those are also essential. As an obligate aerobe, Y. lipolytica has significantly more respiration - related genes that are classified as essential than do S. cerevisiae and S. pombe. The findings provide insights into biosynthetic pathways, compartmentalization of enzymes, and distinct functions of paralogs. Contributions of nonessential genes to fitness were determined in log growth cultures with glucose and glycerol carbon sources. Fluorescence-activated cell sorting identified mutants in which lipid accumulation is increased. Biological contributions of genes to growth were used to evaluate two recent genome-scale models Y. lipolytica metabolism. This study is the first functional genomic analysis of an oleaginous yeast and provides an important resource for modeling and bioengineering of Y. lipolytica.
