BIOHUMAX® contains over 50 types of bacteria and not less than 9 types of moulds. They can be subdivided depending on the temperature range into psychrophiles (t<20°С), mesophiles (t=20°-40°С) and thermophiles (t>40°С). The predominant microorganisms in the end product are mesophiles.

Although bacterial content in the compost is very high (108 -109 cells per 1 g moist compost), due to their small size they comprise less than 50 % of the total microbe biomass. Some species (genus Bacillus, Clostridium) form endospores, resistant to high temperatures and draught. Actinomycetes grow significantly slower than bacteria and moulds and during the early stages of composting they are no competition. They appear at the later stages of the process, when they become too many and form at a depth of 10 cm below the surface a clearly visible layer of actinomycetes, white or grey in color. They can reach up to 105-108 cells per 1 g of moist compost, which is less than the bacteria. Moulds play an important role in cellulose decomposition and the condition of the composting mass should be regulated in such a way as to optimize their activity. Temperature is an important factor, because moulds die at t<55°С. Moulds contain both thermophiles (growing at t=50°С), and mesophiles (growing at t=28°С). After temperature is reduced, they again proliferate in the cooler areas throughout the entire mass.
