Also spelled mold, in biology, a conspicuous mass of mycelium (masses of vegetative filaments, or hyphae) and fruiting structures produced by various fungi (division Mycota). There are thousands of known species of molds, which include opportunistic pathogens, exclusive saprotrophs, aquatic species and thermophiles. Like all fungi, molds derive energy not through photosynthesis but from the organic matter on which they live. Typically, molds secrete hydrolytic enzymes from predominantly the hyphal tips. These enzymes degrade complex biopolymers such as starch, cellulose and lignin into simpler substances which can enter the hyphae. In this way, molds play a major role in causing decomposition of organic material, enabling the recycling of nutrients throughout ecosystems. Many molds also secrete mycotoxins which, together with hydrolytic enzymes, inhibit the growth of competing microorganisms. Molds reproduce through small spores. Mold spores can be asexual (the products of mitosis) or sexual (the products of meiosis), and many species can produce both types. They may contain a single nucleus or many. Some can remain airborne indefinitely, and many are able to survive extremes of temperature and pressure. Although molds grow on dead organic matter everywhere in nature, their presence is only visible to the unaided eye when mold colonies grow. A mold colony does not comprise discrete organisms, but an interconnected network of hyphae called a mycelium. Nutrients and in some cases organelles may be transported throughout the mycelium. In artificial 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. 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.

Cameo Originally Answered: Mould mites on everything?
First I must say that these bugs don't normally just show large scale in a house. Everyone does have some though. The difference is their way of living. An abate human sheds 3 pounds of skin annualy in their home. The majority of this is in your bed. That's probably where your problem started. It sounds to me like this is on a big scale. You need to contact a pest company. This is not something your average Joe can take care of. They will probably tell you to stay out of your house for a day or two for them to kill all the mites. Not because it takes two days to do it but because it takes two days before you can enter your house without dying from the chemicals yourself. To keep this from happening again, follow a few simple steps. Bathe every day. This keeps skin shedding down to a minimum. Change your sheets once or twice a week. No less. Remember, your bed is the most bug infested furniture because you spend a third of your life in it. Lastly, vacuum at least once every two weeks. Don't forget to use the extension on your sofa. Hope this helps.

Mould is a type of fungus. It starts from spores, as all fungi do. There are different species of mould spores always in the air. When they land on nutrients they begin to grow. Yeast is not a fungus or mould. It's a single-celled organism. Therefore it doesn't have spores, and proliferates simply by division of each cell.

Alyssa Originally Answered: Why am i getting black mould on newly plastered wall?
I am wondering if the plasterer mixed too much water into the plaster solution. It's hard to know if an air brick will solve the entire problem, but it surely wouldn't hurt. Is it possible that there is a small leak in the roof, and the water is traveling down to that wall? Could wind be pushing rain into the eave or rake area. Maybe there is a problem with the gutter or downspout not being installed properly. Wish I could be more decisive, but doing the above detective work may help you define the problem. If the mold is not spreading, try the bleach solution, then keep a close eye on the area.

Have they plastered over airbricks? (Edt: I made an assumption that you didn't have damp before the plastering. Also, mould is usually a problem with air circulation. If it was was a leak or rising damp it would be a wet or stain rather than mould - old houses normally have airbricks. If the walls are just drying then accelerate it perhaps with some heating and if you internal walls had render as well as skim plaster then only put an emulsion with no vinyl on them for the first 18 months, so they can carry on drying out)
