Microbiology (from Ancient Greek μῑκρος (mīkros) 'small' βίος (bíos) 'life' and -λογία 'study of') is the scientific study of microorganisms, those being of unicellular (single-celled), multicellular (consisting of complex cells), or acellular (lacking cells).

Total viable count (TVC), gives a quantitative estimate of the concentration of microorganisms such as bacteria, yeast or mould spores in a sample.The count represents the number of colony forming units (cfu) per g (or per ml) of the sample.
Medical microbiology, the large subset of microbiology that is applied to medicine, is a branch of medical science concerned with the prevention, diagnosis and treatment of infectious diseases. In addition, this field of science studies various clinical applications of microbes for the improvement of health.
Diagnostic microbiology is the study of microbial identification. Since the discovery of the germ theory of disease , scientists have been finding ways to harvest specific organisms. Using methods such as differential media or genome sequencing , physicians and scientists can observe novel functions in organisms for more effective and accurate ...
Plate count agar (PCA), also called standard methods agar (SMA), is a microbiological growth medium commonly used to assess or to monitor "total" or viable bacterial growth of a sample.
In microbiology, a colony-forming unit (CFU, cfu or Cfu) is a unit which estimates the number of microbial cells (bacteria, fungi, viruses etc.) in a sample that are viable, able to multiply via binary fission under the controlled conditions. Counting with colony-forming units requires culturing the microbes and counts only viable cells, in ...
Subsequently, aliquots of the sample are taken to test for the antimicrobial activity of a specific drug or protein (antimicrobial peptides). Liquid cultures of the cyanobacterium Synechococcus PCC 7002. Static liquid cultures may be used as an alternative. These cultures are not shaken, and they provide the microbes with an oxygen gradient. [6]
