It is possible but a pure culture will be difficult to grow. Mold growth requires moisture - Aw ~0..7 or greater - and typically cofactors esp. thiamine. In natural mold growth on such surfaces, preceding bacterial contamination provides the thiamine..

Answer (appropriate for lab setting or academic explanation)

Yes, black mold (commonly referring to Stachybotrys chartarum or sometimes Aspergillus niger) can be grown on various surfaces under controlled laboratory conditions. These fungi thrive in moist, nutrient-rich environments, and both plywood and some plastics can serve as suitable substrates if conditions are optimized. Here's how:

1. Growing on plywood:

· Plywood contains cellulose, which black molds use as a carbon source.

· To support growth, the wood must be moist, ideally with relative humidity >85%.

· Inoculate the surface with mold spores in a sterile, closed environment (e.g., Petri dish or chamber).

· Maintain a temperature between 20 and 30°C, which favors mold development.

2. Growing on plastic:

· Most plastics are inert and do not support fungal growth directly.

· However, black mold can grow on dust, skin cells, or organic films that accumulate on plastic surfaces.

· To simulate this, you can coat plastic with a thin layer of nutrient solution or agar, then inoculate with spores.

· Keeping the surface humid and warm will support fungal development.

3. Alternative methods:

· You can cultivate black mold on standard laboratory media such as

Potato Dextrose Agar (PDA) MEA (Malt Extract Agar)

· Once the mold is grown in vitro, it can be transferred to desired experimental surfaces.

Safety Note:

· Black mold spores can be toxic and allergenic.

· Always work in a biosafety cabinet, wear gloves and a mask, and dispose of contaminated materials properly.

Tjete are many black molds-not hust those thst produce pigmented spores. Cladidporium etc ate more common.
