In concentrated fruit drinks and preserves, due to low aw (0.90), only osmophilic yeasts can grow; molds can also grow if oxygen is available. Fruits and . The microorganisms associated with fruits depend on the structure of fruit. Microorganisms includes yeasts, molds, bacteria, protozoa, helminths (worms), and viruses. Although their microflora is dominated by spoilage bacteria, yeasts, and molds, fruits and vegetables can harbor pathogenic bacteria such as Salmonella, Escherichia coli, Bacillus cereus, Campylobacter spp., Yersinia enterocolitica, Listeria monocytogenes, and Clostridium botulinum, as well as some viruses and parasites [ 6 ]. Pickles can be spoiled by yeasts and halophilic bacteria, especially if the acidity is not sufficient. It is also possible for pathogens to survive without increasing in number, and this is of particular concern in Produce contains hundreds of species of bacteria, many more than the few species a person can get from probiotic supplements.
