What Is Actinomycetes?

Actinomycete refers to a group of bacteria, yeasts and molds that are not strictly fungi but have some similarities. They are all members of the same order (Myxenia) and belong to the phylum (Class) Actinia. There are over 200 species of actinomycetes, with many more undescribed. Most actinomycetes are found only in soil or decaying organic matter such as leaves, woody debris and dead animals. Some actinomycetes grow on plants, others do not. Actinomycete fungi can cause disease problems in humans if they contaminate food or water supplies.

The term “fungus” is used here to refer to any organism that grows from rotting material. Actinomycetes are classified into two groups: those that produce spores and those that don’t. Spores are tiny living organisms that carry genetic information inside them; they give fungi their characteristic characteristics.

Most actinomycete fungi produce spores when they die, either naturally or through human intervention. These fungal reproductive structures, such as the powdery white mold (Actinomycete) on this rotten mushroom, are very small.

Over 650 different species of actinomycetes have been described to date. Most actinomycetes live in soil or decaying organic matter but some can be found in the upper layers of the skin and in the air.

The word “actinomyces” means “ray fungus,” and is the singular form of the word. The word comes from the Latin actinia, meaning “a ray.” Fungi that belong to the class actinomycetes are called actinomycetes.

Like plants, fungi make their own food from sunlight (photosynthesis). Fungi also need water and nutrients, just like plants. Since they do not have the ability to move on their own, fungi must either grow towards a potential food supply or, like mushrooms, attract animals to transfer their spores.

Many actinomycetes live in soil (which contains many nutrients) or on decaying organic matter such as leaves and woody debris. Fungal growth also breaks down dead organisms, recycling them back into soil. They are among the most important living things in the soil.

The word “fungus” comes from the Latin word for mushroom, which itself comes from the Latin word fungere or fangere meaning “to rot.” So it is only natural that most people think of mushrooms as the only fungi, yet they are just a small part of this diverse kingdom.

About Fungi

Fungi come in an incredible variety of forms and sizes, so defining what actually makes something a “fungus” is a challenge.

Most people would agree that mushrooms and toadstools are fungi, but what about yeasts, molds, mildews, puffball-like structures and microscopic single-celled organisms?

For the purposes of this article, we’ll consider any organism that doesn’t photosynthesize and breaks down dead or dying organic matter a fungus. This will give us a group of organisms that are diverse in many ways and includes types such as yeasts, molds, mildews, mushrooms and multicellular organisms such as puffball-like structures.

Fungi do not have chlorophyll, the chemical that allows plants to carry out photosynthesis. Because they don’t have their own source of food, they either get it from the organic material they eat or from a host plant (sometimes both).

Mushrooms are the most commonly recognized fungi. Other types of popular fungi include molds, mildews and yeast. Fungi are vital to the breakdown and recycling of dead plant or animal matter, which is why they not only grow in soil but also on dead vegetation and animals. This is why mushrooms are sometimes called toadstools.

They can grow anywhere there is organic material that has started to decay.

Some types of fungi can also be beneficial to humans by helping them break down wastes and rotting material. Some are used for food such as mushrooms and truffles, while others provide dyes for clothing and ink for printing books. Fungi can even help make medicines more effective.

Other types of fungi are harmful to people. For instance, molds can cause allergic reactions and mildews can leave structures damaged if not removed. Some mushrooms contain toxins that can be poisonous or even deadly.

Most Fungi Doesn’t Look Like Mushrooms

Most people think of mushrooms when they hear the word “fungus.” However, only a few types of fungi actually have a mushroom-like appearance. Many more grow in other strange ways.

For example, some types of fungi grow like plants, sending out projections from a main “stem” that may look like roots or branches. Other types of fungi, such as coral fungi, grow in masses that look like coral.

Then there are the types that don’t look like plants or animals at all, but instead are microscopic organisms that can only be seen through a powerful microscope.

Fungi Reproduction

Most fungi reproduce using small, lightweight spores. Depending on the type of fungus, these spores may be released into the air by wind or water, or they may be released by other mechanisms.

One type of sporing mechanism visible to the human eye is the mushroom. Many kinds of mushrooms release their spores from a small hole in the top of the stem, which is where the popular idea of “shooting mushrooms” comes from.

Mushrooms and other types of fungi that rely on spores as their main method of reproduction are called “sporocarps.” The type of structure is called a spore case or sporange.

The type of sporing mechanism that isn’t visible to the human eye includes those that use microscopic spores. Some types of mushrooms don’t look like mushrooms at all, but instead consist entirely of these microscopic spores. One example of this is a yeast, which is a single-celled fungus that multiplies through sporing in the same way as a mold would.

Some Fungi Are Beneficial and Others Are Dangerous

Some types of fungi are beneficial to humans, while others are more dangerous.

For instance, some types of molds and mildews are very dangerous because they can cause allergic reactions to people with sensitive skin or breathing difficulties. Molds that grow on foods can leave them inedible and even toxic.

Other types of fungi grow in the spaces between your home’s walls and floors. These fungi can cause wood to rot, which can then lead to collapsed structures. They can also cause carpeting or padding to rot, leading to a host of potential problems. A few types of these fungi can even cause serious structural issues in concrete.

If you have mold or other types of fungus growing in or on your home, then you need professional help to remove it right away. Even if you don’t think you have a problem, it’s always a good idea to get your home inspected once every few months. If you do find evidence of a potential problem, call a professional as soon as you can.
