Only in certain organs and tissues, for example, in adipose tissue, liver, erythrocytes, possibly adrenal glands, lymph nodes and some other tissues, the oxidation of hexose phosphates in the pentose cycle is essential. 11.4 FERMENTATION TYPES As a result of the vital activity of microorganisms involved in the process of metabolism, a variety of chemical reactions occur, resulting in the formation of valuable substances: alcohols, acids, esters, vitamins and others. They are widely used in various industries, medicine, and everyday life. Many biochemical processes caused by microorganisms, are used in food and light industry. The study of the biochemical activity of microorganisms makes it possible to use them more effectively, to organize the technological process correctly. At the same time, revealing the essence of the changes that occur in food raw materials and products of its processing during the spontaneous development of microorganisms in them contributes to the successful fight against the causative agents of food spoilage. 235
