Project description:A comparison between Y. lipolytica growth in a Synthetic agar Medium not containing THiamin (SM TH-) to its growth in a Synthetic agar Medium supplemented with THiamin (SMTH+) at day 8 of the culture. This study allowed us to discover the effect of thiamin on the growth and the morphology of Y. lipolytica The transcriptomic study was carried out using Agilent 8X15k slides with a custom oligoset designed by V. Loux using the Yarrowia lipolytica ORFeome extracted from genolevures database
Project description:Time-course transcriptomic profilling of the oleaginous yeast Yarrowia lipolytica, during a controlled fed-batch. A nitrogen limitation was applied during the course of the fed-batch to initiate de novo biolipid synthesis.
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.
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.

The Y4184 is an engineered strain to produce eicosapentaenoic acid (EPA) via expression of a Δ9 elongase/Δ8 desaturase pathway, and is derived from Yarrowia lipolytica ATCC#20362.
Project description:Second part of the time-course transcriptomic profilling of the oleaginous yeast Yarrowia lipolytica, obtained during a controlled decellerostat (D-stat) setup. A nitrogen limitation was applied during the course of the D-stat to initiate and control de novo biolipid synthesis. Yarrowia lipolytica Agilent microarray, one-color staining. Each time sample was spotted in triplicate (except for sample 26, for which a technical replicate of replicate r1 was performed).

A nitrogen limitation was applied during the course of the D-stat to initiate and control de novo biolipid synthesis. Yarrowia lipolytica Agilent microarray, one-color staining. Each time sample was spotted in triplicate. A reference condition was spotted in quadruplicate, based on a RNA pool from three samples obtained during the biomass production phase.
Project description:A comparison between the coculture of Debaryomyces hansenii with Yarrowia lipolytica and the monoculture of Debaryomyces hansenii, was carried out at two hours of culture (12h and 27h), in order to understand the metabolic changes induced in D. hansenii when grown in coculture with Y. lipolytica . The transcriptomic study was carried out using Agilent 8X15k slides with a custom oligoset designed by V. Loux using the Debaryomyces hansenii ORFeome extracted from genolevures database
Project description:Time-course transcriptomic profilling of the oleaginous yeast Yarrowia lipolytica, during a controlled fed-batch. A nitrogen limitation was applied during the course of the fed-batch to initiate de novo biolipid synthesis. Dual staining, one replicate per slide. On each slide, a time point sample and a reference sample are spotted. Reference samples were obtained by pooling the RNAs from the time-course samples.
