A microbiological culture, or microbial culture, is a method of multiplying microbial organisms by letting them reproduce in predetermined culture medium under controlled laboratory conditions. Microbial cultures are foundational and basic diagnostic methods used as research tools in molecular biology .
The liquid culture pasteur developed allowed for the visulization of promoting or inhibiting growth of specific bacteria. This same technique is utilized today through various mediums like Mannitol salt agar, a solid medium. Solid cultures were developed in 1881 when Robert Koch solidified the liquid media through the addition of agar [2]
With this culturing method, about 50 to 60 percent of bacterial species are able to survive. [2] Notably, the bacterial species Eleftheria terrae , which makes the antibiotic teixobactin that has shown promise against many drug-resistant strains like methicillin-resistant Staphylococcus aureus , was discovered using the ichip in 2015.
for viral culture detection Hungate Anaerobic tubes: for culturing of anaerobic microbes Incubator: used for bacterial or fungal cultures Inoculation loop: used to inoculate test samples into culture media for bacterial or fungal cultures, antibiograms, etc. Sterilized by passing through a blue flame. Laminar flow cabinet: used to work aseptic
Culturomics is the high-throughput cell culture of bacteria that aims to comprehensively identify strains or species in samples obtained from tissues such as the human gut or from the environment. [ 1 ] [ 2 ] [ 3 ] This approach was conceived as an alternative, complementary method to metagenomics , which relies on the presence of homologous ...
Microbial food cultures are live bacteria, yeasts or moulds used in food production. Microbial food cultures carry out the fermentation process in foodstuffs. Used by humans since the Neolithic period (around 10 000 years BC) [1] fermentation helps to preserve perishable foods and to improve their nutritional and organoleptic qualities (in this case, taste, sight, smell, touch).
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".
[1] [2] Microbes are important in human culture and health in many ways, serving to ferment foods and treat sewage, and to produce fuel, enzymes, and other bioactive compounds. Microbes are essential tools in biology as model organisms and have been put to use in biological warfare and bioterrorism. Microbes are a vital component of fertile soil.
