Abstract excerpt
The Bacillus subtilis L-42 mutant strain, which displays limited growth and inability to cope with hyperosmotic shock in a defined medium with a K+ concentration of < 1 mmol/L, was isolated by non-specific transposon insertional mutagenesis followed by an enrichment selection in media with K+ concentration < 0.5 mmol/L. The growth rate (as the main physiological characteristic) was determined to test the...
