Abstract: | Abstract Bacillus subtilis NCTC 8236 spores exposed to appropriate concentrations of test biocides (glutaraldehyde, two iodine and two chlorine preparations) were able to repair injury if subsequently held in nutrient broth at 37°C but not in broth at 22°C, sterile filtered water at 4, 22 or 37°C or germination medium at 37°C. Repair appeared to occur primarily during outgrowth and was initiated soonest for iodine-treated spores and latest for glutaraldehyde-treated ones. |
