The influence of different carbon sources on growth and single cell oil production in oleaginous yeasts Apiotrichum brassicae and Pichia kudriavzevii.

Oleaginous yeasts offer an interesting possibility for renewable lipid production, since the single cell oil accumulated can be based on a wide range of cheap, waste-derived carbon sources. Here, several short chain carboxylic acids and sugars commonly found in these substrates were assessed as carbon sources for Apiotrichum brassicae and Pichia kudriavzevii. While both strains were able to utilize all carbon sources employed, high volumetric lipid productivities (0.

Arrangements of Mobile Genetic Elements among Virotype E Subpopulation of Sequence Type 131 Strains with High Antimicrobial Resistance and Virulence Gene Content.

Escherichia coli sequence type 131 (ST131) is known for its contribution to multidrug resistance and the worldwide spread of this clone has become a global problem. Understanding the trends among ST131 clades will help design strategies to prevent its rapid dissemination. In this study, 72 ST131 strains were subjected to comparative genomic analysis and 64 clade C strains were compared with clade C strains reported from other regions using publicly available whole-genome sequencing data.
