how and at what temperture does mold grow?

Answer 1

Mold Growth


There are thousands of known species of molds. Their main energy source is organic matter which is broken down by enzymes released from the mycelia (the mass of hyphae) into simpler compounds. By decomposing organic matter, molds play a big part in material biodegradation, enabling decay and rot necessary in all ecosystems. The enzymes and mycotoxins can also inhibit the growth of other molds and microorganisms. Some mycotoxins are considered to be harmful to health. Adequate humidity and temperature are needed for optimal growth. Molds do not mold is also very Molds reproduce through small spores, which can remain airborne indefinitely.

Spores are able to survive extreme temperatures and pressure.


Some molds can begin growing at temperatures as low as 2°C. When conditions do not enable growth, molds can remain alive in a dormant state, within a large range of temperatures before they die.

This explains how molds can survive harsh conditions such as containers in refrigerators or inside building structure cavities. Moving air may prevent mold from growing since it has the same desiccating effect as lowering humidity.

Although molds grow on organic matter everywhere in nature, their presence is only visible to the unaided eye where conditions allow mold colonies to grow. In man-made environments, humidity and temperature are often stable enough to foster the growth of mold colonies, commonly seen as a downy or furry coating growing on food or surfaces. Thus buildings, being stable environments, enable mold proliferation.


Stilton cheese contains edible mold.Although the presence of mold may indicate unwanted decomposition, some molds are cultivated deliberately for their byproduct compounds. Examples include making certain types of moldy cheese, and for the production of antibiotics derived from their natural defenses against bacteria. Alexander Fleming's famous discovery of the antibiotic penicillin came from the mold Penicillium notatum.

Answer 2

different mold can grow at different temperature but most mold can grow at room temp
