A new full-length cDNA (PsD6) putatively encoding a ∆6-desaturase was cloned from the eicosapentaenoic acid-producing fungus Pythium splendens RBB-5. PsD6 contained an open reading frame of 1380 bp encoding a protein of 459 amino acids. The deduced amino acid sequence showed high similarity to those of other ∆6-desaturases. A recombinant vector expressing(More)
Dissolved oxygen (DO) is an important influencing factor in the process of aerobic microbial fermentation. Spinosad is an aerobic microbial-derived secondary metabolite. In our study, spinosad was used as an example to establish a DO strategy by multi-scale analysis, which included a reactor, cell and gene scales. We changed DO conditions that are related(More)
BACKGROUND The Pythium splendens is a potentially useful organism for the synthesis of large amounts of eicosapentaenoic acid. Peak biomass and lipid accumulation do not occur at the same time and growth temperature has an effect on the fatty acid composition. Little is known about the pathway or the genes involved in growth, lipid synthesis or temperature(More)
The fungal microbiota is an important component of the human gut microbiome and may be linked to gastrointestinal disease. In this study, the fungal microbiota of biopsy samples from adenomas and adjacent tissues was characterized by deep sequencing. Ascomycota, Glomeromycota and Basidiomycota were identified as the dominant phyla in both adenomas and(More)
Non-volatile electronic devices based on magnetoelectric multiferroics have triggered new possibilities of outperforming conventional devices for applications. However, ferroelectric reliability issues, such as imprint, retention and fatigue, must be solved before the realization of practical devices. In this study, everlasting ferroelectric retention in(More)
Predicting and understanding the cation distribution in spinels has been one of the most interesting problems in materials science. The present work investigates the effect of cation redistribution on the structural, electrical, optical and magnetic properties of mixed-valent inverse spinel NiCo2O4(NCO) thin films. It is observed that the films grown at low(More)
Heterologous reconstitution the polyunsaturated fatty acid biosynthetic pathway of Phaeodactylum tricornutum in Arabidopsis thaliana Abstract: The genes encoding Δ6 desaturase, Δ6 fatty acid elongase, and Δ5 desaturase from the alga, Phaeodactylum tricornutum, were co-expressed in Arabidopsis thaliana under the control of the Brassica napus napin promoter(More)
