Chu 13
CHU 13 medium is a culture medium used in microbiology for the growth of certain algal species, first published by S.P. Chu in 1942. It is used as growth medium for the biofuel candidate alga ''Botryococcus braunii''.C. Largeau, E. Casadevall, C. Berkaloff and P. Dhamelincout (1980) Phytochemistry, 19, 1943. CHU 13 includes essential minerals and trace Chemical element, elements that are required by algae for growth, but does not include a carbon source and so is only appropriate for growth of phototrophs. It can be prepared as either a liquid medium or as an agar medium. The remaining volume is pure, de-ionized water. Because it is difficult to weigh out some of the trace minerals, it is advisable to create a mixture of all components at a large concentration, such as a thousand times these measures, and then mix with the appropriate amount of (pure, de-ionized) water. Correct pH to 7.5, and then autoclave. References Microbiological media Algaculture {{Microbiology-s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Culture Medium
A growth medium or culture medium is a solid, liquid, or semi-solid designed to support the growth of a population of microorganisms or cells via the process of cell proliferation or small plants like the moss '' Physcomitrella patens''. Different types of media are used for growing different types of cells. The two major types of growth media are those used for cell culture, which use specific cell types derived from plants or animals, and those used for microbiological culture, which are used for growing microorganisms such as bacteria or fungi. The most common growth media for microorganisms are nutrient broths and agar plates; specialized media are sometimes required for microorganism and cell culture growth. Some organisms, termed fastidious organisms, require specialized environments due to complex nutritional requirements. Viruses, for example, are obligate intracellular parasites and require a growth medium containing living cells. Types The most common growth me ...
