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 term culture can also refer to the ...
Durham tubes are used in microbiology to detect production of gas by microorganisms. They are simply smaller test tubes inserted upside down in another test tube so they are freely movable. The culture media to be tested is then added to the larger tube and sterilized, which also eliminates the initial air gap produced when the tube is inserted ...
Vacutainer. Boiling tube. Centrifuge tube. A test tube, also known as a culture tube or sample tube, is a common piece of laboratory glassware consisting of a finger-like length of glass or clear plastic tubing, open at the top and closed at the bottom. Test tubes are usually placed in special-purpose racks .
Autoclave. used for sterilization of glass ware and media. Auto-destruct syringes. specimen collection. Bijou bottle. a cylindrical small glass bottle with a screw cap used as a culture medium holder. Biosafety cabinet. used to work with dangerous organisms and to work sterile. Blood collection bottle.
Mycobacteria Growth Indicator Tube (MGIT) is intended for the culture, detection and recovery of mycobacteria. The MGIT Mycobacteria Growth Indicator Tube contains 7 mL of modified Middlebrook 7H9 Broth base. The complete medium, with OADC enrichment and PANTA antibiotic mixture, is one of the most commonly used liquid media for the cultivation ...
Unlike obligate anaerobes however, they are not poisoned by oxygen. They can be found evenly spread throughout the test tube. A microaerophile is a microorganism that requires environments containing lower levels of dioxygen than that are present in the atmosphere (i.e. < 21% O 2; typically 2–10% O 2) for optimal growth. [ 1]
Inoculation loop. An inoculation loop (also called a smear loop, inoculation wand or microstreaker) is a simple tool used mainly by microbiologists to pick up and transfer a small sample of microorganisms called inoculum from a microbial culture, e.g. for streaking on a culture plate. [1] [2] This process is called inoculation .
In vitro ( Latin for "in glass"; often not italicized in English usage [ 3][ 4][ 5]) studies are conducted using components of an organism that have been isolated from their usual biological surroundings, such as microorganisms, cells, or biological molecules. For example, microorganisms or cells can be studied in artificial culture media, and ...
