What Is Acremonium?
Acremonium is a term used to refer to over 100 types of mold that can grow in a person’s home and in other areas. It was identified in the early 1800s, although it was called Cephalosporium until 1971. It typically refers to asexual molds, which makes it a genus in the fungi imperfecti group.
Most of the Acremonium species are saprobes in the soil, which means that they can play an essential role in the nutrient cycle. However, there are a variety of species that are known to be pathogens to people, as well as quite a large number of them that are harmful to animals.
Where Can Acremonium Grow In The House?
With the various health implications that Acremonium may have, it can be helpful to be aware of the typical areas in the house it can grow. Like every other type of mold, it will need a significant amount of moisture to grow. In most cases, it will thrive in areas that offer water activity levels in the 0.90 to 0.98 range.
This usually means that they can be quite common in buildings that have experienced any kind of water damage. The material that a building or room is made from doesn’t seem to make much of a difference. This is because it’s been known to grow on concrete, wallpaper, plaster, drywall, plywood, wood, fiberglass, and much more.
Alongside this, there are a few specific areas in a building that it’s more likely to grow than others. Some of the more common areas include:
- Laundry Rooms
How To Identify It
Because Acremonium typically grows inside drywall and insulation, it can oftentimes be quite difficult to locate. Alongside this, identifying its spores in a spore trap may be much more challenging than many people think. The main reason for this is that the spores can often be colorless and much smaller than expected.
Despite this, there are a few notable ways that you may be able to identify Acremonium. Colonies typically come in a few specific colors, most notably orange, pink, gray, or white. If found early enough, then they may also be quite moist. However, it can take a powdery form over time, especially if it’s been growing for a significant period. The biggest reason why Acremonium is so hard to identify visually is simply that it shares various physical similarities with other types of mold. Lab testing is the only way to know for sure what type of mold you are dealing with.
