Abstract
We present here a CRISPR-interference-based protocol to trigger prophage induction, even for non-inducible prophages. This method can also be used to cure the prophage from the bacterial host. The method is based on silencing of the phage's repressor transcription, thanks to CRISPR interference. Plasmid electroporation is used to bring the CRISPRi system into the bacteria, specifically on a plasmid carrying spacers targeting the prophage repressor. This method enables prophage induction and curation in a week or two with a high efficiency.
