Analysis Note

A purified agar in which the original naturally occurring pigments, salts and miscellaneous matter have been reduced to a minimum.

Application

Bacteriological agar has been used:
  • as a component of ATCC agar for Escherichia coli culture[1]
  • as one of the experimental diet feed for Atlantic salmon fry, to study the protein and lysine requirements for maintenance and for tissue accretion[2]
  • as component of yeast extract peptone dextrose medium, Luria broth medium and synthetic complete drop out medium for Escherichia coli culture[3]

Biochem/physiol Actions

Bacteriological agar is commonly used as a culture medium for microorganism. It is useful for fermentation process. Agar-agar serves as a preservative in food processing. It also possesses various other applications such as an emulsifier, carrier, lubricant, stabilizer, laxative disintegrant in pharmaceutical and cosmetic industries. Agar-agar is also used in photographic emulsion.[4]

General description

Bacteriological agar is a colloidal substance and a cell wall component, obtained from Rhodoyceae (marine algae)[5] and Gelidium sp.[4] Agarose combined with agaropectin forms this polysaccharide. It is also called as agar-agar and is a polymer of galactoside. This agar is soluble in boiling water but not in cold water.[4]

Questions

1–2 of 2 Questions  
  1. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  2. 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
