Water is necessary for life, but many people lack access to clean and safe drinking water, and many die as a result of bacterial diseases contracted through water. Microorganisms that dwell in water or can be moved from one habitat to another are studied in water microbiology. Many different types of microorganisms can grow in water. This could be beneficial. Beer and bread, for example, are made possible by the chemical activity of certain yeast strains. In addition, the proliferation of some bacteria in contaminated water can aid in the digestion of the chemicals in the water. The presence of other disease-causing bacteria in water, on the other hand, is hazardous and even deadly.
The study of living microbes suspended in the air is known as aeromicrobiology. Bioaerosols are microbes that live in the atmosphere. Despite the fact that there are many less atmospheric microorganisms than in oceans and soil, there are still enough to have an impact on the atmosphere. Once suspended in the air column, these microorganisms have the ability to move long distances with the help of wind and precipitation, increasing the likelihood of widespread disease. These aerosols are important to the environment because they have been linked to sickness in humans, animals, and plants. In the spread of infectious diseases, aerobiology plays a critical role. Practitioners of infectious illness and infection control continue to use cutting-edge methods.
