• Meat peptone is sourced from hydrolyzed proteins of animal tissue. This peptone consists of soluble amino acids and peptides that provide readily available nitrogen and other essential growth factors. It is primarily used for the cultivation of fastidious and non-fastidious microorganisms in microbiological culture media.

  • Malt extract is sourced from hydrolyzed vegetal protein. Due to the high concentration of carbohydrate malt extract is particularly suited for the cultivation of yeasts and moulds especially in contaminated dairy products. In microbiological culture media it provides a source of nutrients, protein, and carbon.

  • Soy peptone is manufactured from the enzymatic hydrolysis of soybean. This product provides a good source of nitrogen, carbohydrates, and vitamins. It is recommended for use in microbiological media for the detection and isolation of a wide variety of bacteria and fungi.  
    Details
  • Lactalbumin hydrolysate is obtained through enzymatic hydrolysis of lactalbumin protein in milk whey. This product is rich in essential amino acids as well as providing a source of nitrogen, carbon and vitamins. It is commonly utilized in media for tissue culture and for the production of vaccines as well as being useful for bacterial and fermentation media.  
    Details
  • Brain-heart infusion solids is a dehydrated infusion of porcine brains and heart. This product can be used in preparing microbiological culture media providing nitrogen, vitamins, minerals and amino acids.  
    Details
  • Bacteriological agar is extracted from several species of red algae, Gelidium spp. Bacteriological agar is a solidifying agent used in the preparation of microbiological culture media.This agar is suitable for all bacteriological purposes and has a low concentration of metal ions.A firm gel is obtained at working concentrations of 1.0 to 1.5%.  
    Details
  • Letheen broth modified is intended for use in the isolation of microorganisms from cosmetics. The enzymatic digest of animal tissue, enzymatic digest of casein, yeast extract and beef extract act as carbon, nitrogen and vitamin sources in this medium. Sodium chloride maintains the osmotic balance of the medium. The sodium bisulfite and lecithin inactivates quaternary ammonium compounds. Polysorbate 80 must be added to the medium prior to sterilisation. Polysorbate 80 neutralises phenols, formalin, hexachlorophene, and in combination with the lecithin, ethanol.
