Does freezing streile water?
Freezing sterile water will not kill any microorganisms that may be present in the water. Freezing can actually preserve these microorganisms until the water is thawed. To eliminate microorganisms, water needs to be sterilized through methods such as boiling or using chemical disinfectants.
What is microbial loading?
Microbial loading refers to the amount of microorganisms present in a given environment, such as air, water, or surfaces. It is a measure of microbial contamination and can be quantified by assessing the concentration or number of viable microorganisms in a sample. High microbial loading can increase the risk of infection or spoilage.
Where is cell present?
Cells are present in all living organisms, from the simplest single-celled microorganisms to complex multicellular organisms like plants and animals. Cells make up the basic units of structure and function in living organisms.

This smell is due to the amount of proteins that the pigs are eating and the microorganisms that are present in the manure. These microorganisms that are found in manure are anaerobic, meaning that they begin to work in the presence of air; they will break down and degrade the manure. This process is what causes the bad odour of the manure. The more protein that the animal is fed, the more microorganisms that will be present, causing more rancid smells.
