Thus, the plate can be used either to estimate the concentration of organisms in a liquid culture or a suitable dilution of that culture using a colony counter, or to generate genetically pure cultures from a mixed culture of genetically different organisms. Several methods are available to plate out cells. One technique is known as "streaking".

used to stain microscopic slides to get contrast Hot air oven: used in sterilizing instruments for various aseptic procedures, specially if that can not be autoclaved like powders Koch's or Arnold's steam sterilizer: used for steam sterilization A pressure cooker: used as a portable autoclave Biological and chemical indicators
Indole test positive: appearance of pink layer at top (e.g. Escherichia coli) Like many biochemical tests on bacteria, results of an indole test are indicated by a change in color following a reaction with an added reagent.
Microbial cytology: the study of microscopic and submicroscopic details of microorganisms; Microbial physiology: the study of how the microbial cell functions biochemically. Includes the study of microbial growth, microbial metabolism and microbial cell structure; Microbial pathogenesis: the study of pathogens which happen to be microbes
The milk, or latex, that oozes when the mushroom tissue is cut or broken (a feature common to all members of the genus Lactarius) is also indigo blue, but slowly turns green upon exposure to air. The cap has a diameter of 4–15 cm (2–6 in), and the stem is 2–8 cm ( 3 ⁄ 4 – 3 + 1 ⁄ 8 in) tall and 1–2.5 cm ( 3 ⁄ 8 –1 in) thick.
The gold standard for detecting bacteriuria is a bacterial culture which identifies the concentration of bacterial cells in the urine. The culture is usually combined with subsequent testing using biochemical methods or MALDI-TOF, which allows to identify the causal [citation needed] bacterial species, and antibiotic susceptibility testing ...
For this, the average of existing cells is performed in the field of the microscope, dividing total somatic cells from microscopic factor (MF) which corresponds to the number of fields in one inch, i.e. 100 mm, obtaining in this way the number of somatic cells per milliliter of milk.
