What is subculture microbiology?
What is subculture? Subculturing, also referred to as passaging cells, is the removal of the medium and transfer of cells from a previous culture into fresh growth medium, a procedure that enables the further propagation of the cell line or cell strain.
What do we mean by subculture?
According to Oxford English Dictionary (the OED), subculture, means “an identifiable subgroup within a society or group of people, especially one characterized by beliefs or interests at variance with those of the larger group”. Originally “subculture” indicated a particular group of people and their culture.

What is the purpose of Subculturing bacteria?
Subculturing describes the transfer of microbes from one growth medium container, such as broth or agar, to another, and allowing the microbes to grow. Subculturing is also useful in keeping strains alive by transferring them to fresh growth medium.
How do you subculture E coli?
Autoclave 15 g agar in 800 ml water for 15 min. Add sterile concentrated minimal medium and carbon source. After medium has cooled to about 50°C, add supplements and antibiotics. Pouring 32 to 40 ml medium into each plate, expect about 25 to 30 plates per liter.
What are 5 examples of subculture?
Examples of subcultures include the hippies, hipsters, cosplay, hip hop, punks, emos, and goths. Subcultures are also usually associated with youth and often seen with some degree of suspicion by older people.
What precautions should be taken during Subculturing?
Care should be exercised in the opening of tubes with tight caps to prevent the breakage of the glass. Care should be taken to avoid contact with skin, eyes, or mucous membranes when handling culture media or any laboratory reagent, stain, fixative, or chemical. If contact occurs, flush immediately with running water.
How do you grow bacteria overnight?
Note: A good negative control is LB media + antibiotic without any bacteria inoculated. You should see no growth in this culture after overnight incubation….Antibiotic Concentrations.
| Commonly Used Antibiotics | Recommended Concentration |
|---|---|
| Coumermycin | 25 µg/mL |
| Gentamycin | 10 µg/mL |
| Kanamycin | 50 µg/mL |
| Spectinomycin | 50 µg/mL |
How is it possible to contaminate a subculture?
It is possible to contaminate a subculture because the air around us is full of microorganisms.
What is the purpose of bacterial subculture?
Microbiologists use subculturing techniques to grow and maintain bacterial cultures, to examine cultures for purity or morphology, or to determine the number of viable organisms. In clinical laboratories, subculturing is used to obtain a pure culture of an infectious agent, and also for studies leading to the identification of the pathogen.
What is a subculture in microbiology?
Subculture (biology) In biology, a subculture is a new cell or microbiological culture made by transferring some or all cells from a previous culture to fresh growth medium. This action is called subculturing or passaging the cells. Subculture is used to prolong the life and/or expand the number of cells or microorganisms in the culture.
