NEOGEN Agar, Technical, 500 g
Agar, Technical is a solidifying agent for use in preparing microbiological culture media in a laboratory setting. Agar, Technical is not intended for use in the diagnosis of disease or other conditions in humans. Conforms to US Pharmacopeia (USP).Agar is a phycocolloid extracted from a group of red-purple algae, usually Gelidium spp. Agar was first suggested for microbiological purposes in 1881 by Fannie Hesse. By the early 1900’s, agar became the gelling agent of choice over gelatin because agar remains firm at growth temperatures for many pathogens and agar is generally resistant to a breakdown by bacterial enzymes. The use of agar in microbiological media significantly contributed to the advance of microbiology, paving the way to study pure cultures.For more information visit https://www.neogen.com/solutions/Microbiology/agar-technical

This ingredient is suitable for yeasts and molds because it contains a high concentration of carbohydrates, particularly maltose. The approximate percentage of reducing sugars in Malt Extract is 60 – 63%.The high carbohydrate content makes malt extract very sensitive to overheating which results in darkening of the medium it is used in. Malt Extract is generally employed in culture media at concentrations between 10 to 100 grams per liter.For more information visit https://www.neogen.com/solutions/Microbiology/malt-extract
