Pectin agar (Pectin, KH 2 PO 4, K 2 HPO 4, MgSO 4.7H 2 O) SmF : Bacillus tequilensis SALBT: Pectin agar: SmF : Aspergillus fumigatus: Pectin agar: SSF : Aspergillus niger ATCC 120120 (NH 4)SO 4, MgSO 4.7H 2 O, KH 2 PO 4, FeSO 4.7H 2 O, yeast extract, glucose and pectin of Nephrolepis biserrata leaves: SSF : Aspergillus sp. Furthermore, agar is significantly more strong than gelatin: It is equivalent to 8 teaspoons of gelatin powder to use a teaspoon of agar powder. Archived from the original on 16 March 2015. Gelatin can have a creamy texture, whereas agar can have a firmer texture, depending on the amount of gelatin used. Czapek and Dox did not add agar but many recipes add 15 g to make a solid medium. Also, you should note that agar agar powder will set up much faster than pectin once it is dissolved. This makes the medium a selective growth medium as only organisms that can use inorganic nitrogen can grow. 0.01 g iron sulfate – source of cations Īrthur Wayland Dox added 2 g of sodium nitrate in his version, to provide a sole source of nitrogen that is inorganic.0.5 g potassium chloride – source of essential ions.0.5 g magnesium sulfate – source of cations.1 g dipotassium phosphate – buffering agent. ![]() 30 g cane sugar – energy source and sole source of carbon.Aspergillus bertholletius on Czapek agarįriedrich Czapek's original recipe is as follows: It works well for many saprophytic fungi and soil bacteria such as species of Aspergillus, Candida, Penicillium, and Paecilomyces. It was developed to grow Aspergillus niger and Penicillium camemberti. It was named after its inventors, Czech botanist Friedrich Johann Franz Czapek (– July 31, 1921) and American chemist Arthur Wayland Dox (Septem– 1954). Aspergillus tubingensis growing on Czapek mediumĬzapek medium, also called Czapek's agar ( CZA) or Czapek-Dox medium, is a growth medium for propagating fungi and other organisms in a laboratory.
