Microbiological science has never been limited to the study of any one group of microscopic living things. All those organisms, from bacteria to higher fungi inclusive, whose vital activity is of practical or scientific and cognitive interest, fell into her attention. In this regard, the field of microbiological research is expanding from year to year. In addition to food, medical and soil microbiology, new sections of microbiological science have emerged over the past 10 to 20 years. In particular, microorganisms have gained great value as producers of physiologically active substances such as enzymes, antibiotics, amino acids and vitamins.
