Eugon LT 100 Agar
Eugon LT 100 agar is used for the enumeration of total mesophilic aerobic microorganisms in cosmetic products with or without preservatives. It enables luxuriant colonies to form in the case of most microorganisms.
The typical composition corresponds to that defined in the standard NF EN ISO 21149.
Available in dehydrated medium : 500 g bottle
Also available as:
- Ready-to-use medium : 20 Petri plates Ø 90 mm (BM17008).
- Ready-to-melt medium : 10 vials of 200 ml (BM04508).
In compliance with regulatory requirements, a USDA permit (VS 16-3) is mandatory for shipments from Canada to the USA due to the inclusion of peptone, an animal byproduct.
The medium is composed of a mixture of peptones, cystine, glucose and salts which favor the growth of a wide variety of microorganisms.
Sodium chloride maintains osmotic pressure.
Lecithin and Polysorbate 80 (tween) neutralize the antibacterial activity of most antiseptics or preservatives, such as phenolic derivatives, aldehydes and quaternary ammonium salts.
Triton X-100 favors the dispersion of cells and thus improves enumeration.
