Which would prevent a plant from being able to grow?

Answer 1

Many people are mistaken that bleach and other household chemicals kill fungus. Wrong. The only way to inhibit fungal growth is by drying out the area rigorously making the fungus try to live without moisture..... which is impossible.

Answer 2

The kind of environment needed to grow fungi is in wet or damp places such as: • On the end of cold water taps (usually kitchen or bathroom) • In washing machines (particularly around the powder drawer) • In filter jug hoppers and elements • In toilet cisterns and bowls • In shower heads • Around tiles in bathrooms / shower rooms • On shower curtains or towels (often appears as spots or staining) • In waste traps connected to sinks so if that does not help then i cant do much more.

Factors that affect the growth of mouldsSeptember 14, 2005 By MBL

The major factors affecting growth of mould are nutrients, temperature, light, aeration, pH and water activity.

Nutrients

Nutrient requirements for moulds may vary from mould to mould. Some moulds may thrive well on substrates with high sugar or salt content. Some may prefer simple sugars while others have the ability to utilize complex sugars.

Temperature

The majority of moulds are mesophilic, i.e., they can grow at temperatures within the range of 10-35°C. Optimum temperatures for growth may range between 15 and 30°C. However, some moulds such as Chaetomium thermophilum and Penicillium dupontii are thermophilic, i.e., they can grow at 45°C or higher and fail to grow below 20°C. A few moulds are psychrophilic and are unable to grow above 20°C. A significant number are psychrotolerant and are able to grow both at freezing point and at room temperature.

Light

Many moulds species grow well in the dark, but some prefer daylight or alternate light and darkness for them to produce spores.

Aeration

Nearly all moulds require air to grow.

pH.

Moulds differ in their pH requirements. Most will grow well over the pH range 3-7. Some such as Aspergillus niger and Penicillium funiculosum can grow at pH 2 and below.

Water activity

All moulds require moisture for growth but the amount required varies widely. Moulds that are capable of growing at very low water activity are referred to as xerophiles, for examples Eurotium species and Wallemia sebi. Those that are capable of growing at very high water activity are referred to as hydrophilic, e.g., Stachybotrys, Chaetomium and Ulocladium.

Answer 4

Normally, it would be lack of water and/or food that prevents a fungus from growing. But lots of things can kill fungus; lethal heat, toxicity, radiation, etc. All the things that can kill most other organisms can also kill fungus.

Answer 5

Many things.

* Lack of food * Lack of oxygen * Incompatible environment (too hot, too cold, etc.) * Toxins (antibiotics, anti-microbials, etc.)

Answer 6

lack of sunlight

lack of sunlight

Answer 7

dark, warm, moist area
