A lot of the previous discussions on the different microbes that break down organic matter has focused on mostly bacteria and some fungi. As with a lot of things, it is not that simple. There are a lot of creatures in play to help create compost.
A thriving compost biome will host primary, secondary, and tertiary consumers. Their presence can give you an indication on where your compost is in it's production cycle as well as potential conditions that may be present. By analysing what is in our compost, we can adjust our processes to make a high quality end product.
Actinomycetes are like a bacteria version of fungus. They create a white cobweb like network of hyphae that looks similar to mycelium development. Actinomycetes specialize in breaking down tough materials such as lignin and cellulose.
Nematodes are friends to composters. Instead of the parasitic nematodes that may hurt our growies, there are varieties of nematodes that help break down organic matter and benefit composting. They assist in recycling nutrients and maintaining a healthy biome.
Springtails are a delight to find in my compost. They consume organic matter (cellulose), fungi and mold with vigor. They also can indicate there is plenty of moisture if not excessive moisture in a pile if the springtail population explodes suddenly.
Mold mites are detritivores that enjoy chowing down on decaying organic matter. Their presence in high numbers can indicate excessive moisture and possibly compaction in your pile.
Rotifera are microscopic organisms present in water films that feed on bacteria, fungi, and organic matter. Rotifera are generally found in finished stable compost. Rotifera are sensitive to toxins so their presence is a welcome sign.
