From: Development of butanol-tolerant Bacillus subtilis strain GRSW2-B1 as a potential bioproduction host
Growth of B. subtilis GRSW2-B1 when butanol was added simultaneously with bacterial inoculum in LB medium. Growth of non-acclimatized cells (opened symbol) and acclimatized cells (closed symbol) (expressed as logarithm scale of optical density at 600 nm) was monitored in the absence (×,✶) or presence of various concentrations of butanol (%v): 1.5 (□,■), 1.75 (◇, ◆), 2 (Δ▲), and 2.25 (○,●). Data are means of the results from at least three individual experiments.
