The species most frequently reported in vinegar production comprise AcetobacterAcetobacter is a genus of acetic acid bacteria. Acetic acid bacteria are characterized by the ability to convert ethanol to acetic acid in the presence of oxygen. Of these, the genus Acetobacter is distinguished by the ability to oxidize lactate and acetate into carbon dioxide and water.https://en.wikipedia.org › wiki › Acetobacter
Studies confirming vinegar's antibacterial properties: Household natural sanitizers like lemon juice and vinegar reduced the number of pathogens to undetectable levels. Vinegar can inhibit growth of and kill some food-borne pathogenic bacteria. Plus, vinegar's bactericidal activity increased with heat!
Once opened and exposed to air, however, harmless “vinegar bacteria” may start to grow. This bacteria causes the formation of a cloudy sediment that is nothing more than harmless cellulose, a complex carbohydrate that does not affect the quality of the vinegar or its flavor.
Turbatrix aceti (vinegar eels, vinegar nematode, Anguillula aceti) are free-living nematodes that feed on a microbial culture called mother of vinegar (used to create vinegar) and may be found in unfiltered vinegar. They were discovered by Pierre Borel in 1656.
Specifically, vinegar can kill salmonella, E. coli, and listeria, which is good news for the kitchen. But the kitchen contains other pathogens as well, as does the rest of the house. The bottom line is that vinegar may kill some pathogens, but don't make the mistake of counting on it to do much more than clean.
Even though vinegar is produced by fermentation, it is surprisingly not a probiotic food that contains beneficial bacteria. However, certain vinegars like apple cider vinegar which contains pectin may act as a prebiotic, or food for beneficial bacteria.
The result showed that the dominant bacteria in the dynamic fermentation of apple vinegar are Lactococcus, Oenococcus and Acetobacter.
Vinegar eel, or Turbatrix aceti, are non-parasitic nematodes which thrive in unpasteurised apple cider vinegar, feeding on the bacteria which creates the vinegar. They grow to a maximum of 2mm long, so can just be seen with the naked eye, and have a virtually transparent body.
As vinegar ages, it may undergo aesthetic changes, such as becoming hazy or separating. You may also notice cloudy sediments or fibers at the bottom of the bottle.
Common problems when making apple cider vinegar
Usually, mold on ACV will be black and will form in splotches across the surface and along the glass, although sometimes it can be white or greenish. If you see mold on your ACV you'll need to throw it away and start again.
Mother of vinegar is a colony of bacteria (don't gasp). These are the good bacteria called Acetobacter. They perform the same purpose for making vinegar as yeast does to make wine. They form the mother on the surface since they require oxygen to convert wine to vinegar and the surface is where the air is at.
Vinegar doesn't work well as a disinfectant. According to EPA standards, a disinfectant should be able to kill 99.9 percent of disease-causing bacteria and viruses. Vinegar only works against some germs, like E. coli and Salmonella.
Mixing chlorine bleach, which contains sodium hypochlorite, with any type of acid like vinegar creates chlorine gas, a dangerous chemical that's deadly in high volumes.
Important caveat: If you do choose to use vinegar as a cleaning agent, never mix it with bleach, ammonia, or hydrogen peroxide because any of these mixtures will create toxic gases.
Vinegar eels are not parasitic and will not harm you. Within just a few days of ingesting them, they are on their way out of your digestive system, excreted the same way as any other waste.
Fruit flies and aphids find the smell of vinegar irresistible. If fruit flies or aphids are a nuisance in your home, yard or outdoor buildings, half fill a small bowl with apple cider vinegar and cover it over tightly with plastic wrap.
Though vinegar can be fatal to many common plants, others, like rhododendrons, hydrangeas and gardenias, thrive on acidity which makes a bit of vinegar the best pick-me-up. Combine one cup of plain white vinegar with a gallon of water and use the next time you water these plants to see some amazing results.

As previously mentioned, unpasteurized apple cider is historically considered to be a safe product, free of microbial pathogens due to its acidic level and to the fermentation process. However, some bacterial and parasitic pathogens can survive and may remain infectious [106].
Apple cider vinegar that remains unpasteurized carries a risk of bacteria like E. coli or salmonella. Before you use apple cider vinegar, check that it's pasteurized properly. Most store-bought apple cider vinegar is pasteurized, but check the label to make sure.
'The mother' is the culture of beneficial bacteria that transforms apple cider into vinegar. Organic – or unfiltered – strains of apple cider vinegar containing the mother look murkier, and have been linked with improved health benefits.
Studies show that fermented foods, like vinegar, inhibit the enzymes that help you digest starch, leaving enough starch to feed and encourage the growth of healthy gut bacteria--which is what you want (think better digestion and stronger immune systems).
How does it work? Vinegar, be it white or malt or rosemary-infused, is about 5 per cent acetic acid. The acid kills bacteria and viruses, by chemically changing the proteins and fats that make up these nasties and destroying their cell structures.
