1) In the food industry, bacteria, along with yeasts and molds, have been used for thousands of years in the preparation of fermented foods such as cheese, butter, pickles, vinegar, wine and yogurt.
2) For bioremediation, the use of bacteria has the great advantage that they can degrade a great variety of organic compounds without causing damage to the environment as would occur with chemical products, which is why they are useful in the recycling of waste and for cleaning contaminated environments.

1) The interaction that occurs between bacteria and humans is complex. In the human body there are approximately ten times as many bacterial cells as there are human cells, with a large number of bacteria on the skin and in the digestive tract.
2) Although some bacteria may be pathogenic to humans, the protective effect of the immune system renders the vast majority of them harmless or beneficial. Many other bacteria are found as symbionts in humans and other organisms. For example, about a thousand bacterial species proliferate in the digestive tract.
3) Some bacterial species are even beneficial from a vaccine point of view... En un articulo

1) Within environmental microbiology, we find microbial ecology, microbial diversity, geomicrobiology and bioremediation, rhizoremediation and molecular biology of pseudomonads.
Microbial diversity: Microbial diversity is understood as the knowledge of the enormous variety of microorganisms found in natural ecosystems. Despite being the most abundant organisms on the planet, the study of the diversity of microbes that exist in the world is a relatively new knowledge for humanity and with a lot of field to study and discover yet.
Geomicrobiology: Geomicrobiology is the science that studies the relationships between geochemical and geological processes and microorganisms. Thus, the science encompasses the study of all microbial interaction occurring in water bodies and sediments of the Earth's crust.
Bioremediation, rhizoremediation and molecular biology of pseudomonads: These terms refer to processes that serve to return a contaminated environment to its natural condition through the use of microorganisms, plants, fungi or enzymes derived from them. Microorganisms attack contaminating substances that may be in the soil or water in order to eliminate or neutralize them and restore the stability of the environment.
2) Microorganisms assist in the recycling, decomposition and mineralization of all organic matter in the process of putrefaction. In addition, microbes benefit life on Earth in many other ways. For example, mycorrhizae are a type of microorganism that promote plant defense and growth.
3) Pathogenic microorganisms present in water can make this essential commodity for human survival harmful, just as if these organisms were present in the air.
4) We can say then that environmental microorganisms, whether they have a polluting or decontaminating function, are present in all environments; and that environmental microbiology encompasses a great diversity of fields that are of utmost importance for the well-being of human life. It deals with studies and problems related to human, animal and plant medicine, agriculture, animal production, soil fertility, industry, etc.
5) One of the most transcendental branches of environmental microbiology for us focuses on the study of microorganisms pathogenic to humans. Thus, this science is interrelated with some categories of medicine such as immunology, pathology and epidemiology, with all the importance that these sciences have for the life of people and the advancement of society. It is also related to other sub-branches within microbiology, such as bacteriology or the study of bacteria, a science of vital importance for medical and scientific advances.
