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
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
琼脂已用于植物生长培养基中。
常见的工作浓度是： 6-12g/L。
包装
5, 10, 25 kg in poly drum
1 kg in poly bottle
100, 500 g in poly bottle
生化/生理作用
Agar is gel forming polysaccharide used as a gelling and stabilizing agent. Its serves as a cryoprotectant in processed foods, pharmaceuticals and cosmetics products.
