WebbThey comprise a broad range of diseases caused by microorganisms, chemicals, toxins, radioactivity, or even physical agents present in ingested food or water. Foodborne illnesses constitute a public health problem since they boost morbidity and mortality, causing a significant number of hospitalisations and deaths [ 5, 12, 13 ]. WebbThe resulting uneven distribution of protons generates a pH gradient and transmembrane electrical potential that creates the proton motive force.
