acumedia* Technical Agar

• Intended Use: Agar, Technical is a solidifying agent for use in preparing microbiological culture media. Conforms to US
Pharmacopeia (USP).
• Product Summary: 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 1900s, 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. Agar is a gel at room temperature, remaining firm at temperatures as high as 65°C.
