The influence of growth conditions on strain differentiation within the Lactobacillus acidophilus group using matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry profiling

Abstract excerpt

RATIONALE: Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) profiling of bacteria is often used to distinguish isolates beyond the species level, even to the level of individual strains. However, the influence of bacterial growth conditions on the discriminatory power of the method to the strain level has not yet been properly evaluated. METHODS: For the purpose of this...
