Abstract

AIMS: In this study, bacteriocidal effects of cinnamic aldehyde on Bacillus cereus were investigated. METHODS: The bacterial culture or cell suspension in 0.85% NaCl was treated with cinnamic aldehyde at a concentration of 0.3 ml l(-1). Viable cells were counted on a nutrient agar plate. Protein leakage from the cell was determined using a protein dye. Cell morphology was observed using a scanning electron microscope. RESULTS: Bacillus cereus cells were the most sensitive to cinnamic aldehyde among four different food-borne pathogens. When the cells were treated with 0.3 ml l(-1) of cinnamic aldehyde, the viable counts decreased about 6 log cycles after 6 h of incubation. The bacterial cells remained unlysed although they were killed by cinnamic aldehyde. Treatment of cinnamic aldehyde to the exponential phase cells resulted in no significant protein leakage but strong inhibition of cell separation. CONCLUSIONS: The present findings suggest that cinnamic aldehyde exhibits bacteriocidal effects and inhibition of cell separation on B. cereus. SIGNIFICANCE AND IMPACT OF THE STUDY: These data represent an interesting background for a possible mechanism for antibacterial effects of cinnamic aldehyde.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Cinnamaldehyde causes B. cereus to form elongated, filamentous structures in which the cells do not appear to be separated from one another.

    “Kwon et al. [98] tested the effect of cinnamaldehyde on the morphology of B. cereus and found that without treatment, the bacteria appeared as well-separated rods. However, bacterial cells treated with cinnamaldehyde appeared as elongated, filamentous structures in which the cells did not appear to be separated from one another.”

  • Non-specific inhibition of membrane-bound or -embedded enzymes can be caused by small hydrophobic molecules as a result of changes in protein conformation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
