How do bacteria affect our lives?
Though most bacteria are beneficial, some are harmful. Certain species multiply within the human body, where they digest tissues or produce toxins resulting in disease. Other bacteria infect plant crops and animal herds. Disease-causing bacteria (i.e., pathogenic bacteria) are a global threat to all life forms, and in the 21st century, they have already been used as agents of bioterror. Bacteria have threatened human existence over the millennia through tuberculosis, bubonic plague, typhus, pneumonia, streptococcal infections, diphtheria, E. coli, and anthrax.
Why are bacteria far flung?
This far-flung distribution is possible because many bacteria have metabolic abilities not found in any eukaryote. Some carry on fermentation, others respiration. Aerobes require O 2 for respiration; obligate anaerobes are killed by O 2; facultative anaerobes can live in the presence or absence of O 2.
Why do bacteria absorb small molecules?
Because of their rigid cell walls, bacteria cannot take in large food particles. Rather, they absorb small molecules that filter through their walls. Many bacteria can make any organic molecule they need by starting with only one kind of organic molecule, such as glucose or fatty acids. Others require a more complex diet. The “picky eaters” are referred to as fastidious. When conditions are unfavorable for growth, some bacteria form thick-walled, resting spores resistant to heat and drying. Most bacterial spores are not a means of reproduction, because no increase in cell number occurs. Rather, spore formation permits cells to survive adverse conditions and disperse to new locations, where a new cell may develop from the spore.
What do bacteria do with sewage?
Bacteria digest sewage into simple chemicals; extract nitrogen from the air and make it available to plants for protein production; break down the remains of everything that dies, recycling the carbon and other elements; and produce foods for human consumption and products for industrial technology.
How do bacteria survive?
They can be isolated from Arctic ice, thermal hot springs, the fringes of space, and the tissues of animals. Some can withstand the searing acid in volcanic ash, the crushing pressures of ocean trenches, and the powerful activity of digestive enzymes. Other bacteria survive in oxygen-free environments, boiling water, and extremely dry locations. In short, they are ubiquitous (everywhere). The Creator must love them because they are the closest things to omnipresence on earth. Bacteria have so completely invaded the earth that the mass of bacterial cells is estimated to outweigh the mass of all plants and animals combined. They are Providence’s prokaryotic wonders.
Why do we love bacteria?
The Creator must love them because they are the closest things to omnipresence on earth. Bacteria have so completely invaded the earth that the mass of bacterial cells is estimated to outweigh the mass of all plants and animals combined.
What bacteria are in milk?
Bacterial growth can spoil the milk or even pose a serious health hazard if pathogenic bacteria are present. Diseases that can be transmitted from an infected cow include tuberculosis ( Mycobacterium tuberculosis ), undulant fever ( Brucella abortus ), and Q fever ( Coxiella burnetii ). In addition, typhoid fever ( Salmonella typhi) can be transmitted through milk from an infected milk handler. Pasteurization procedures increase the temperature of the milk to 63 °C (145 °F) for 30 minutes or to 71 °C (160 °F) for 15 seconds, which kills any of the pathogenic bacteria that might be present, although these procedures do not kill all microorganisms.

Art of Manipulating Man Lecture One: How Can Bacteria Be Helpful?
Welcome class, to the first lecture on The Art Of Manipulating Man! Today we will discuss how can bacteria and other microbes be helpful. Not my favorite topic on manipulating man but you all should know the benefits of microbes to humans before we really learn how to manipulate the giants!
Understanding Microbial Diversity
The giants think they have this ‘diversity thing’ covered. They think biodiversity is just the 8 million species of plants and animals on earth. HA! What If I were to tell you that this estimate is but one star in all universes of diversity?
1. Benefits Of Microbes: We Get Them Drunk!
Let’s start off with maybe one of the most important things microbes do for man, ferment. But fermentation is not just alcohol, which some would argue has had plenty of negative effects on man.
2. How Can Bacteria Be Helpful? By Providing Essential Nutrients
Truth be told, those humans wouldn’t last a day without us. Despite all their “chemistry” and “vitamins”, they are still novices in the world of material engineering. So many of their essential nutrients are because we give it to them, literally we just hand it to them for basically free.
3. We Fight Diseases For Them In The Environment
When you guys graduate you'll likely find yourself as part of a microbiome. Microbiomes are like a neighborhood and like any neighborhood, they can be quite dynamic.
4. We Fight Diseases For Them In Their Bodies
The giants really are quite fragile creatures, filled with fallacies and weak points, which our kind has no doubt exploited throughout time. But our kind, again and again, comes to the giant's aid in their time of tragedies to restore normalcy and defend them from the unknown. In many ways, we are like their guardian angels.

Why are bacteria important to the environment?
Bacteria help degrade dead animals and plants and bring valuable nutrients back to Earth. Some species also help clean harmful pollutants out of the environment in a process called bioremediation. By using bioremediation techniques, ...
What are the risks of bioremediation?
Heavy metals from industry and toxic synthetic organic chemicals, including pesticides, petroleum products, explosives and flame retardants, pose serious environmental and health risks . They enter soil, air and water and are extremely resistant to natural breakdown processes. Bioremediation uses certain bacteria that digest toxic substances and convert them into less harmful substances. To some degree, bioremediation occurs naturally, but it is usually enhanced by adding bacterial "food," such as phosphorus and nitrogen, which make bacteria grow better and clean chemicals more effectively. Bioremediation is usually less expensive and less labor-intensive than traditional technologies.
What are the most important organisms in soil?
Significance. The most numerous organisms in the soil are bacteria. They are a necessary part of nutrient, or biogeochemical, cycles in which carbon, nitrogen, sulfur and phosphorus are recycled between living beings and the environment.
Is bioremediation harmful to the environment?
By using biore mediation techniques , toxic substances such as heavy metals and petroleum are no longer harmful to the environment. Bacteria are also cheap and accurate sensors of toxic chemicals. Advertisement.
Is bioremediation a natural process?
To some degree, bioremediation occurs naturally, but it is usually enhanced by adding bacterial "food," such as phosphorus and nitrogen, which make bacteria grow better and clean chemicals more effectively.
