Objective To screen the Bacillus strains producing 4'-hydroxyacetophenone by liquid chromatography/quadrupole time-of-flight mass spectrometry (LC-QTOF-MS). Methods Extracellular metabolites of 20 Bacillus strains were analyzed by LC-QTOF-MS. The information of total metabolites was obtained by molecular feature extraction and spectral library search. Results The results showed that only one Bacillus strain, Bacillus fordii FJAT-10032 that producing 4'-hydroxyacetophenone. The exact mass of the compound was 136.0522. The relative content of 4'-hydroxyacetophenone was 1.39% with match score of 90.97. Conclusion This study provides the theory basis for the development and utilization of Bacillus fordii FJAT-10032, which can produce 4'-hydroxyacetophenone.
