  • Production of vineger with bacteria on a support
    Patent number: 4661356
    Abstract: A process for producing vinegar is carried out by inoculating and growing acetic acid bacteria on a lipophilic fibrous support packed in a fermentation tower, and forcing a charging wort for vinegar production and an oxygen-containing gas to contact with and pass through said bacteria on the support to carry out acetic fermentation. The fiberous support is preferably fibers of polypropylenes, polyethylenes, polystyrenes, polyethyleneterephthalate or polyurethanes.
