How do you make Czapek Dox broth?
Czapek Dox Broth is a semisynthetic medium used for the general cultivation of fungi. Suspend 35.01 grams in 1000 ml distilled water. Heat if necessary to dissolve the medium completely. Sterilize by autoclaving at 15 lbs pressure (121°C) for 15 minutes.
Why PDA is used for fungus?
Potato Dextrose Agar is composed of dehydrated Potato Infusion and Dextrose that encourage luxuriant fungal growth. Chloramphenicol acts as a selective agent to inhibit bacterial overgrowth of competing microorganisms from mixed specimens, while permitting the selective isolation of fungi.
What type of agar is best for growing fungi?
Sabouraud’s dextrose agar (2%) is most useful as a medium for the subculture of fungi recovered on enriched medium to enhance typical sporulation and provide the more characteristic colony morphology.
What media is used for growing fungi?
The media most commonly used are nutrient agar (bacteria), potato dextrose agar (fungi), and Sabouraud dextrose agar (fungi).
What media do fungi use?

What is the best agar for mycology?
Malt Extract Agar

Why did Arthur Wayland Dox add agar to Czapek?
Arthur Wayland Dox added 2 g of sodium nitrate in his version, to provide a sole source of nitrogen that is inorganic. This makes the medium a selective growth medium as only organisms that can use inorganic nitrogen can grow. Czapek and Dox did not add agar but many recipes add 15 g to make a solid medium.
How much yeast extract is in MY50G agar?
MY50G agar has the following composition: malt extract 10 g; yeast extract 2.5 g; glucose 500 g; agar 10 g; water 500 g; sterilize by steaming for 30 min. The final medium is about pH 5.5 and 0.89 a w. If glucose monohydrate is used, add 550 g and reduce water to 450 g.
What is the composition of yeast extract in agar?
MY70G agar has the following composition: malt extract 6 g; yeast extract 1.5 g; glucose 350 g; fructose 350 g; agar 6 g; water 300 g; sterilize by steaming for 30 min. Final medium is about pH 5.5 and 0.75 a w. If glucose monohydrate is used, add 385 g and reduce water to 265 g.
What kind of Media do you use to detect yeast?
Detection of any of these fungi requires growth on isolation media and identification on standard media, such as Czapek yeast extract agar (CYA) and malt extract agar (MEA) used for Aspergillus and Penicillium species.
