一般說明

细菌琼脂是胶状物质和细胞壁组分,来源于红藻(海藻)[1]和石花菜。[2]这种多糖由琼脂糖和硫琼胶共同组成。它又名洋菜(agar-agar),是一种半乳糖苷聚合物。琼脂可溶于沸水,与冷水不能相溶。[2]

應用

细菌琼脂已用于:
  • 用作培养大肠杆菌的ATCC琼脂的组分[3]
  • 用作大西洋鲑鱼苗的一种实验饲料,研究饲养和组织沉积的蛋白和赖氨酸需求[4]
  • 用作酵母提取物蛋白胨葡萄糖培养基、Luria肉汤(LB)培养基和合成完全营养缺陷型培养基的组分,用于大肠杆菌培养。[5]

生化/生理作用

细菌琼脂通常用作微生物培养基。它可用于发酵工艺。琼脂可用作食品加工的防腐剂。它还可用作制药和化妆品业中的乳化剂、载体、润滑剂、稳定剂、泻药崩解剂。琼脂还可用于感光乳剂。[2]

品質

纯化琼脂,其中原始的天然存在的色素、盐及其他物质的含量已降低到最低。

Questions

1–2 of 2 Questions  
  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
