一般描述

琼脂是一种从海藻(Rhodophyceae)中获得的亲水性胶体。它可溶于沸水，而这对微生物学领域具有重要意义。
Agar chemically consists of two fractions: agarose, a neutral polymer of high gel strength and agaropectin, a non-gelling fraction with sulfated β-1,3-glycosidically linked D-galactose units.

应用

Agar has been used:

• as a reference standard commercial agar to compare the physio-chemical, gelling properties of alkali-treated agar from Gracilaria tenuistipitata
• as a component in the seed germination medium and rooting medium for commercially available soybean (Glycine max (L.) Merr) seeds
• as a component of growth media for B. subtilis mutant strain MTC871 based biofilm colonies
• as a bacteriological agar component to prepare half strength Murashige-Skoog (MS 50%) medium for Echinocactus platycanthus seeds culture
