摘要: The invention provides methods of screening a microbial host cell for a property of interest in a microfluidic device, the method comprising the steps of: a) transforming a d-alanine racemase-deficient microbial host cell with a polynucleotide construct comprising: i) one or more polynucleotide region providing the property of interest when present in the host cell, and ii) at least one polynucleotide region complementing the d-alanine racemase deficiency when present in the host cell; and b) screening the transformed host cell for the property of interest in the microfluidic device in the absence of externally provided d-alanine.

摘要: The present invention relates to a method of identifying control sequences responding to antimicrobial peptides (AMPs), to host cells expressing an AMP and comprising a control sequence of the invention operable linked to a reporter, and to a method of screening for novel AMPs or AMP-variants having improved antimicrobial activity. Particularly the present invention relates to DNA control sequences, wherein the transcriptional profiles of said control sequences are regulated by the presence of an antimicrobial polypeptide expressed inside the host cell.
