Overview

Tiny, unicellular organisms that are invisible to the human eye are known as microbes. Because they could only be observed under a microscope, they are often referred to as microbes or microscopic organisms. They comprise over 60% of all living things on Earth. For growth and the preservation of their metabolic processes, microorganisms need a few essential nutrients. Depending on the type of microbe, different amounts and types of nutrients are needed. Amino acids, alcohols, and carbohydrates can all provide energy for microorganisms. Simple carbohydrates like glucose are metabolized by the majority of bacteria. More complex carbs like cellulose or starch, as well as the glycogen present in diets for muscles, can be metabolized by others. Fatty acids can be used as an energy source by certain microbes. Most microbes need amino acids, which are a source of energy and nitrogen. More complex proteins and peptides can be metabolized by certain microbes. Ammonia, urea, creatinine, and methylamines are a few more sources of nitrogen. The cow, the equipment used for milking, storing, and transportation, as well as the surroundings, are the sources of microorganisms in raw milk. With the use of modern technologies, milk may be collected with very few microbes. On the other hand, a very varied microbial population might be present in milk. The microorganisms that cause spoiling and pathogenicity in milk are the ones that are most interesting. Microorganisms that produce lactic acid, propionic acid, butyric acid, and degradative enzymes are classified into one of four physiological classes. When given the right conditions to flourish in, some spoilage organisms--like lactic acid bacteria--can be exploited to make fermented dairy products. The pathogenic bacteria found in milk have the potential to be toxic or contagious. Additionally, there are just two sources of hydrogen atoms or electrons for microorganisms. Lithotrophs are those who obtain their electrons from reduced inorganic compounds. Microbes classified as organotrophs are those that take electrons or hydrogen atoms (each hydrogen atom has one electron) from organic substances.
