Food poisoning is mainly caused by pathogenic microorganisms and is now a severe problem worldwide. Therefore, rapid and sensitive methods are required to detect foodborne pathogens. A locally isolated bacterium, Bacillus licheniformis B38 was selected for this study. The spores of B. licheniformis B38 were induced by Schaeffer’s sporulation medium containing KCl, MgSO4.7H2O, Ca(NO3)4, MnCl2 and FeSO4. Schaeffer-Fulton endospore staining was used to differentiate spores and vegetative cells, where spores were stained green and vegetative cells were stained red. In order to separate the spores from the cells, a two-phase system was used to obtain pure spore suspension for following experiments. Spore coat proteins were extracted by SDS-8 M urea sample buffer and visualized by two different types of coomassie brilliant blue staining solutions. One of the staining solutions was more suitable for gel elution by diffusion. An ~10 kDa spore coat protein was selected for protein purification. Based on the given results, the protein purification by liquid chromatography was less convincing than using gel elution by diffusion technique. The two hypothetical protein sequences, P06552 and P45693, from the ~10 kDa spore coat protein were identified. In the preliminary study of B. licheniformis B38 spores detection by surface plasmon resonance, several binding parameters were studied. Dot blot was done to verify the reaction between the Bacillus spores polyclonal antibody against the B. licheniformis B38 spore coat protein. The most promising result was the binding of 0.1 mg/mL polyclonal antibody (analyte) to the 0.2 mg/mL spore coat protein at pH 2 (ligand) which showed 5.74 RU. The differences between a dot blot and a SPR detection techniques are described.
