found this interesting different microbes working at diff temps .
The Psychrophilic Stage
During winter months, cold-loving psychrophilic bacteria are often the only ones on the scene, and are usually found in temperatures between 0°C and 20°C. As they break down the organic matter a small amount of heat is generated, which slowly but surely builds. When the temperature hits 20°C it becomes too warm for the psychrophilic bacteria and mesophilic bacteria take over.
The Mesophilic Stage
This stage is often the first, especially if you start your compost during the summer. Mesophilic bacteria break down organic matter into proteins and carbohydrates, constantly generating heat as they do so. Once the temperature of the compost reaches 40°C, the mesophilic bacteria are replaced by heat-loving thermophilic bacteria.
The Thermophilic Stage
Thermophilic bacteria break down organic matter extremely quickly and as a result, the temperature rises fast and the breakdown of proteins, fats and complex carbohydrates accelerates. When the supply of high-energy compounds is depleted, the temperature starts to drop, which sees the thermophilic bacteria disappear and the mesophilic bacteria return.
The Curing Stage
The curing stage sees the mesophilic bacteria sharing the workload with fungi and actinomycetes, and together they break down the remaining organic matter. The longer the curing stage, the more diverse its microbial community will be, meaning healthier and more nutrient-rich soil.
