Transcriptional response of desaturase genes to low temperature was investigated in the dimorphic fungus Mucor rouxii. The two morphological forms of M. rouxii, yeast-like and mycelial cells containing different fatty acid profiles were shifted from 30 to 10°C. Both cultures exhibited significantly altered fatty acid composition, whose content in(More)
We identified a novel elongase gene from a selected strain of the Oomycete, Pythium sp. BCC53698. Using a PCR approach, the cloned gene (PyElo) possessed an open reading frame (ORF) of 834 bp encoding 277 amino acid residues. A similarity search showed that it had homology with the PUFA elongases of several organisms. In addition, the signature(More)
Microbial lipids are promising alternative sources of long chain-polyunsaturated fatty acids (LC-PUFAs) for food, feed, nutraceutical and pharmaceutical sectors. Dihomo-γ-linolenic acid (C20:3Δ(8,11,14); DGLA) is an important LC-PUFAs with anti-inflammatory and anti-proliferative effects. To generate a DGLA-producing strain, fatty acid reconstitution in(More)
BACKGROUND The ∆(6)-desaturase gene, encoding a key enzyme in the biosynthesis of polyunsaturated fatty acids, has potential in pharmaceutical and nutraceutical applications. RESULTS The ∆(6)-desaturase gene has been isolated from a selected strain of Oomycetes, Pythium sp. BCC53698. The cloned gene (PyDes6) contained an open reading frame (ORF) of 1401(More)
