Single-guide RNA (sgRNA) is RNA designed artifially to be able to bind to a DNA sequence. It combines with the Cas9 protein to work to cleave the target RNA and though it is slightly shorter, it has the same function as the original RNAs in the CRISPR/Cas9 system. We designed the sfp_target(gRNA) to target  the region of the natural sfp gene to knock-out and simultaneously knock-in sfp (Part number:BBa_K4274009) and degQ (Part number:BBa_K4274010) gene in situ. After the sucessful modification, Bacillus subtilis 168 was allowed to produce fengycins. This could be reused by other teams to edit the genome of Bacillus subtilis and thus realize fengycins’ production.
