The present invention provides anti-bacterial compositions comprising whole cells of an Aneurinibacillus bacterium designated as NH (ATCC #XXX) or an anti-bacterial protein expressed by the NH bacterium. Additionally, the present invention provides methods of using the anti-bacterial compositions to inhibit the growth of bacteria such as Campylobacter jejuni and Listeria monocytogenes.

The invention relates to a process for treating food, in particular for curing meat, comprising adding to the food a compound of Formula III, which is a derivative of S-nitroso-cysteine. Use of the compound of Formula III as food preservative and compositions for curing meat are also provided by the invention.

A clove essential oil Pickering emulsion-based coating preservative, and a preparation method and use thereof. Preparing a 20 mg/ml zein solution with ethanol and a zein powder, preparing a 0.4 mg/ml to 6 mg/ml sodium caseinate solution with ultrapure water and sodium caseinate, and conducting magnetic stirring overnight; adding the zein solution dropwise into the sodium caseinate solution, and conducting magnetic stirring; conducting evaporation on the ethanol in the zein solution, and replacing evaporated ethanol with the ultrapure water; adding a clove essential oil, and conducting high-speed homogenization for 3 min to obtain a clove essential oil Pickering emulsion; and preparing a 1.5% w/v to 2% w/v chitosan solution with 1% v/v acetic acid and chitosan, adding the clove essential oil Pickering emulsion to the chitosan solution, conducting high-speed homogenization for 3 min, and conducting ultrasonic defoaming for 30 min to obtain the clove essential oil Pickering emulsion-based coating preservative.

According to one embodiment, a method for removing antimicrobial material from a composition includes providing a container that contains a plurality of carbon elements such as granules, rocks and sheets. The carbon elements are submerged with a liquid and a composition that includes an antimicrobial material is deposited in the container. The carbon elements are configured to remove the antimicrobial material from the composition. The level of the liquid in the container is monitored and controlled to maintain a submerged condition of the carbon elements.
