Introduction to Mould

Moulds can be found on plants, in the soil, or on dead or decaying matter. Moulds are essential for the decomposition of leaves, wood, and other vegetation outside. Moulds are members of the kingdom of fungi. Since they are not plants and lack chlorophyll, they must consume plant matter and other organic materials in order to survive. Without moulds, the amount of dead plant matter in our environment would be overwhelming.


To reproduce, moulds release tiny spores similar to how some plants release seeds. Mould spores can be found on indoor and outdoor surfaces as well as in the air indoors and outdoors. Mould spores may start to grow and eat whatever they are growing on when they land on a moist surface. By removing mould growth, one can avoid damage to building materials and furniture as well as save money because moulds gradually deteriorate the things they grow on.

What is a Mould?

Moulds are variants of fungi. They differ from other fungi in a number of ways. They are larger than yeasts, which typically have a single cell, but they lack the expanding, obvious structures found in mushrooms. Mould comes in a huge variety of species and types. All over the world, both inside and outside, they grow in wet environments.


Moulds are not able to make their own food, like other fungi. Despite the fact that most moulds eat dead plant and animal tissues, some moulds do consume living things. These can take the form of leaves that have fallen from a tree or products made from plants or animals, such as food, paper, fabric, and a wide range of others.


An English scientist discovered in 1928 that a mould known as Penicillium notatum was capable of eradicating many of the typical human bacteria. From that mould, scientists later produced the medication penicillin. Similar drugs are made using other moulds. Blue cheese is one of the cheeses that can be made using moulds. Moulds help in removing fallen leaves and dead trees from forests.


Moulds often grow in buildings that have too much moisture. These moulds can cause such illnesses as rashes, breathing problems, and lung infections. Moulds can also ruin foods. If bread, cheese, and fruits and vegetables are allowed to sit too long, mould spores in the air can land on them and begin to grow. As they grow they eat away at the food.


Types of Mould

Mould comes in a wide variety of forms. 

  • Rhizopus stolonifer, also referred to as black bread mould, is one of the more prevalent varieties. And despite its name, it also likes other foods like fruits and vegetables.

  • Penicillium, which is a well-known variety of moulds and the source of the antibiotic Penicillin, is another. Penicillium can be found in many different places, including water-damaged buildings and different foods.

  • Aspergillus is a mould that is known to come in a number of cancer-causing varieties and, when found indoors, can seriously affect respiratory health.

What is Mould Fungi?

A fungus is referred to as mould. These can be found in any indoor or outdoor environment and are either green, purple, black, white, or orange in colour. As long as there is oxygen nearby, they can thrive. Spores that are airborne and of light nature are used for their reproduction. Although they are unharmful in small quantities, if they land on a moist surface, they will begin to grow. The spores will begin to release from them, and once they do, they can be inhaled to travel to the respiratory system. As a result, it may cause illness in people.


What is a Bread Mould?

Bread mould is a simple fungus that takes food and nutrients from the bread and damages the bread surface. Mould growing on the bread can be microscopic fungi belonging to different species like Penicillium, Rhizopus, Aspergillus, Monascus and Fusarium. They are of different shapes and colours depending on the species.

Summary

The kingdom of fungi includes mould, which is a type of fungus. Additionally, mould, yeast, mushrooms, lichens, and truffles are members of the kingdom of fungi. Moulds are fungi with filaments. Fine, branching filaments called hyphae make up mycelium (singular hypha).

FAQs on What is a Mould?

1. What are bread moulds made of and what are the three types of moulds?

Several species of moulds – identified as “bread moulds” – grow on bread. They form when mould spores find their way onto the surface of the bread. Mould is a fungus that eats the organic compounds found in bread and other foods. Penicillium, Cladosporium and black bread mould are three common bread moulds.


The more common moulds that most homeowners encounter can be classified into three categories: allergenic, pathogenic, and toxic. Allergenic moulds can require removal by a professional, but most allergenic moulds can be removed with home disinfecting products.

2. Is fungi a mould?

Mould and fungus are two types of organisms that belong to the kingdom of Fungi. The main difference between mould and fungus is that mould is a multicellular, filamentous fungus whereas fungus is a unicellular or multicellular organism with a chitin cell wall. Fungi include moulds, mushrooms, and yeast.

3.  What is the difference between bacteria and fungi?

The main difference between bacteria and fungi is that bacteria are unicellular prokaryotic organisms whereas fungi are multicellular eukaryotic organisms. Both bacteria and fungi contain DNA as their genetic material. The genetic material of bacteria is organised in the cytoplasm.
