Biomass yields of multiple lytic-gene deletion mutants. (a) OD600 of cultures of wild-type and multiple-deletion mutants:■ Wild-type, ★ LM2, × LM25, ▲ LM253, ● LM2531, ▼ LM25314; (b) 12 h viable cell numbers: 1 B. subtilis 168, 2 LM2, 3 LM25, 4 LM253, 5 LM2531, 6 LM25314. There was no significant difference between the biomass of each of the two sets of multiple-deletion mutants, and therefore data for one set is presented here. The data represent the mean and SD from triplicate measurements of three different colonies of the same genotype for each mutant.
