    Abstract: The present invention relates to methods for modifying the genome of a Bacillus host cell by employing a Class II Cas9 enzyme with only one active nuclease domain, e.g. the S. pyogenes Cas9 nickase, together with a suitable guide RNA for each target sequence to generate a site-specific nick in at least one genome target sequence followed by the repair of the nick(s) via integration of one or more modified modified donor part of the Bacillus host cell genome through classical double homologous recombination on each side of the nick(s).
