The risk of fruit juice contamination caused by microorganisms, especially Alicyclobacillus acidoterrestris, has been reported worldwide. To develop cost-effective control methods, in this work, flower-like magnetic molybdenum disulfide (Fe 3 O 4 @MoS 2 ) nanoparticles (NPs) were fabricated by a facile two-step hydrothermal method. After further modifying polyacrylic acid (PAA) on the surface of the NPs, epsilon-polylysine (EPL) was immobilized via N -(3-dimethylaminopropyl)- N -carbodiimide hydrochloride/ N -hydroxysuccinimide coupling reaction to obtain the Fe 3 O 4 @MoS 2 @PAA–EPL nanocomposites. Antibacterial results exhibited that the synthesized nanocomposites showed effective antibacterial activity against A. acidoterrestris with a minimum inhibitory concentration of 0.31 mg mL –1 . Investigation on the antibacterial mechanism revealed that the presence of nanocomposites caused damage and disruption of the bacterial membrane through dent formation, resulting in the leakage of intracellular protein. Moreover, the activity of dehydrogenase enzymes was inhibited with the treatment of Fe 3 O 4 @MoS 2 @PAA–EPL, causing the reduction of metabolic activity and adenosine triphosphate levels in bacteria. Simultaneously, the presence of nanocomposites improved intracellular reactive oxygen species levels, and this disrupted the antioxidant defense system and caused oxidative damage to bacteria. Furthermore, Fe 3 O 4 @MoS 2 @PAA–EPL nanocomposites were confirmed to possess satisfactory biocompatibility by performing in vitro cytotoxicity and in vivo acute toxicity experiments. The aim of this research was to develop a new pathway for the inhibition of A. acidoterrestris in the juice industry. |
