Abstract: Acetic acid is one of the important weak acids which had long history in chemical industries. This weak organic acid has been widely used as one of the key intermediate for many chemical, detergent, wood and food industries. The production of this acid is mainly carried out using submerged fermentation system

1997). In one approach, ethanol. which is produced by yeast fermentation. is aerobically converted to acetic acid by Acetobacter. In the other approach, glucose/cellulose is converted to acetic acid, usually using thermophilic Clostridium spp. High concentrations of acetic acid are produced in the yeast-Acetobacter process
by their ability to convert ethyl alcohol (C2H5OH) into acetic acid (CH3CO2H) by oxidation. Vinegar can be produced from various raw materials like distilled alcohol, wine, rice wine and any kind alcoholic solution by several major production techniques for making vinegar such as the Orleans process, generator process

acetic acid fermentation of dilute alcoholic solutions. Aerobically, food-grade acetic acid is produced by the two-step vinegar process. The first step is the production of ethanol from a carbohydrate source such as glucose which is carried out by yeasts and the second step is the oxidation of ethanol to acetic acid carried out
Strictly aerobic acetic acid bacteria (AAB) have a long history of use in fermentation processes, and the conversion of ethanol to acetic acid for the production of vinegar is the most well-known application. At the industrial scale, vinegar is mainly produced by submerged fermentation, which refers to an aerobic process in
Anaerobic process is one stage process carried out by Clostridium. Aerobic fermentation is two stage processes. Glucose is converted into ethanol by S.cerevesiae. And second stage is ethanol is converted into acetic acid by acetobacter aceti.
7 Feb 1993 other tnicroorganisms in fermentation processes. In addition to producing propionic and acetic acids, the propionibacteria synthesize a number of other compounds that have potential commercial use: vitamin Bl2, which is currently produced by fermentation with other microorganisms; and bacteriocins
7 Feb 1993 On such group of organisms is the propionibacteria, which produce acetic acid along with their primary product, propionic acid. It is currently produced commercially by chemical synthesis from petroleum, but is also known to be produced by the propionibacteria and a few other microorganisms in fermentation processes.
