    摘要: Fluoroalkyl silanes are a class of compounds useful for various industrial purposes. For example, fluoroalkyl silanes which have hydrolysable groups (called hydrolysable fluoroalkyl silanes), are compounds useful as surface treatment agents which provide durable hydrophobic and oleophobic coatings. In general, hydrolysable fluoroalkyl silanes can be represented with the following formula: (RO—)3Si—RT wherein R is H or an alkyl; and RT is a monovalent organic compound terminated by a perfluoroalkyl group. When used to coat a surface, the (RO—)3 moiety reacts (via hydrolysis) with various chemical groups of the surface (e.g., hydroxyl, amine, or other reactive groups) thereby bonding the fluoroalkyl silane to the surface The RT moiety comprises a divalent organic linking group which links the silicon atom to a terminal group rich in fluorine atoms whose unique electronic properties impart desirable hydrophobic and oleophobic properties in a surface coating. Modification of the RT moiety is useful in the engineering of fluoroalkyl silanes. The present invention provides for fluoroalkyl silanes having RT moieties which have not been heretofore considered.

    摘要: Several endogenous genes have been identified in Escherichia coli, the overexpression of which increases recombinant peptide production. Increasing the copy number of aroB, aroK, proB, or crl increases the amount of a recombinant peptide produced by a host cell. Recombinant host cells comprising at least one chimeric genetic construct encoding a peptide of interest and at least one genetic modification that increases recombinant peptide production are provided as well as methods of using such recombinant host cells
