sacB is a gene obtained from Bacillus subtilis that functions as a negative selection marker. In the presence of 15% sucrose, cells carrying sacB are eliminated, allowing only those that have lost the gene to survive. It was used in a two-step scarless gene replacement technique employing λ Red recombination [146].
