Identification of a Biosynthetic Gene Cluster for the Production of the Blue-Green Pigment Xylindein by the Fungus .

Xylindein is a blue-green pigment produced by the fungi and Its stunning color and optoelectronic properties make xylindein valuable for textiles and as a natural semiconductor material. However, producing xylindein from culture broths remains challenging because of the slow growth of the species and the poor solubility of xylindein in organic solvents. An alternative production route for obtaining pure xylindein is heterologous expression of the xylindein biosynthetic genes.

Genetic analysis of plasmid-encoded resistance in Enterobacteriaceae derived from poultry meat in the Netherlands.

Background: Colistin is classified as the highest priority and critically important antimicrobial for human medicine by WHO as it is the last resort agent for treatment of carbapenem-resistant Enterobacteriaceae in humans. Additional research is necessary to elucidate the genetic structure of resistance genes, commonly found on plasmids, using WGS.

Objectives: To map and compare the genetic characteristics of 35 -mediated colistin-resistant Enterobacteriaceae isolated from chicken meat to highlight the genetic variation of the containing plasmids.
