摘要:The present invention relates to gold binding peptides and shape- and size-tunable synthesis of gold nanostructures. The present inventions are very useful for the production of well-designed, gold-based architectures. The size- and shape-specific gold nanostructure materials prepared by the present invention may find use as: highly conductive interconnections for single-electron transistors, catalysts for the oxidation of carbon monoxide; biological and chemical sensors; and as contrasting agents for electron microscopic and medical imaging applications.

摘要:The invention relates to the field of the microbial production of substituted aromatics. In particular, it relates to the production of hydroxylated aromatics from renewable carbon stocks, like sugars or glycerol, via the metabolic intermediate L-tyrosine. Provided is a microbial host cell capable of producing at least one hydroxylated aromatic from a renewable carbon source, wherein at least one enzyme of said host cell that is involved in the degradation of said at least one hydroxylated aromatic is disabled and wherein the de novo synthesis of L-phenylalanine (L-Phe) in said host cell is impeded. Also provided is a method for the microbial production of at least one hydroxylated aromatic from a renewable carbon source, comprising culturing a host cell in the presence of exogenous L-Phe and a renewable carbon source and allowing said host cell to produce said at least one hydroxylated aromatic.
