    Abstract

    Mycology media

    Steps

    1.

    WA+C agar

    Water agar + chloramphenicol (氯黴素 kill bacteria): As an environmental isolating media

    AB
    ComponentAmount
    Agar20g
    Chloramphenicol0.05g
    DI water1000 ml

    chloramphenicol is autoclavable

    2.

    PDA+C agar

    potato dextrose agar + chloramphenicol (氯黴素 kill bacteria): Use when WA+C agar is not working

    AB
    ComponentAmount
    PDA39g (or per instruction on label)
    Agar5g
    Chloramphenicol0.05g
    DI water1000 ml
    3.

    quarter-strength PDA

    1. Less nutrient than regular PDA (1/4)

    2. For beetle-associated fungi isolation

    AB
    ComponentAmount
    PDA9.75g (or per instruction on label)
    Agar5g
    DI water1000 ml
    4.

    MEA (malt extraction agar)

    For isolate subculture

    AB
    ComponentAmount
    MEA33.6g (or per instruction on label)
    Agar5g
    DI water1000 ml
    5.

    Emerson YpSs Agar : For chytrids

    AB
    ComponentAmount
    Yeast extract4g
    Soluble Starch15g
    K2HPO41g
    MgSO4 x 7H2O0.5g
    Agar20g
    DI water1000ml

    Adujust pH to 7.0 +/- 0.2. Autoclave at 121ºC.

    6.

    10% Unclarified V8 Agar

    1. Combine 100 ml V8 juice and 900 ml of distilled water.
    2. Add 1g CaCO3and 0.05 g b-sitosterol and mix well. Leave stir bar in the flask for later mixing.
    3. Add 15g of agar.
    4. Autoclave at 15 psi for 20 minutes.
    5. Stir medium while dispensing to insure good mixing of CaCO3. 20% : 200 ml V8, 800ml d. water, 2g CaCO3, and 0.05g b-sitosterol.

    15% : 150 ml V8, 850 ml d. water, 1.5g CaCO3, and 0.05g b-sitosterol.

    7.

    SceSel+ medium (Kaltseis et al.,2009)

    For isolation of Scedosporium

    AB
    ComponentAmount
    Malt extract6.25 g
    maltose6.25 g
    KH2PO41.25 g
    yeast extract1 g
    Magnesium Sulfate Heptahydrate0.625 g
    soy peptone0.625 g
    chloramphenicol0.1 g
    ciprofloxacin0.1 g
    streptomycin sulfate0.1 g
    dichloran2 mg
    benomyl6 mg
    DI water1000ml
