What is the Excessive numbers of other bacteria in a sample that can interfere with counting coliform is called?
The excessive numbers of other bacteria in a sample that can interfere with counting coliform is called bacterial interference or bacterial overgrowth. This can lead to inaccurate results when trying to quantify coliform bacteria in the sample.
20 How do facultative anaerobic bacteria differ from the other two?
Facultative anaerobic bacteria can switch between using aerobic and anaerobic metabolism depending on oxygen availability. Obligate anaerobic bacteria cannot survive in the presence of oxygen and rely only on anaerobic metabolism, while obligate aerobic bacteria require oxygen for survival and use aerobic metabolism exclusively.
Why are the majority of bacteria considered heterotrophic?
Heterotrophic means " other eaters " which means these bacteria can not make their own food and much engulf it, whether other bacteria or plant like matter. Autotroph means " own food " and these bacteria preform photosynthesis.
What is the function of an operator in bacteria?
The function of an operator in bacteria can be defined as the required for the transport and metabolism of the lactose in Escherichia coli and some other enteric bacteria. It consist of three adjacent structural genes.
What is chemosynthetic bacteria?
Chemosynthetic bacteria means bacteria that can make chemical things (synthetic). Basically any bacteria are chemosynthetic - they all product different chemicals as part of their metabolism. There are methanogens that produce methane gas, there are photosynthetic organisms that produce oxygen (like plants, and the ancestry of plants), others can produce nitrogen gas, like those bacteria that live in nodules on legume plants. Other bacteria can produce acids from fermentation like proprionic acid which gives Swiss cheese its nutty flavor. So lots and lots of bacteria are chemosynthetic. It just depends on what you want to produce.
What cause bacteria to produse toxins?
What causes bacteria to produce toxins is metabolism. The toxins are not intended to be poisons. They are like the exhaust of a car, they are the biproducts of their body processes of life. So in other words, it's bacterial pee and poo.

How does eubacteria get their food?
they produce by photosynthesis and chemosynthesis. They also eat other bacteria

What do bacteria produce to kill other bacteria apart from toxin?
Some bacteria and other organisms produce antibiotics which mean "against life". These can kill other organisms. The antibiotic penicillin was discovered barbecue an agar plate streaked with a bacteria had a fungus contaminant and an area of clearing was seen around it. This area had an antibiotic made by the fungus and it stopped the growth of the bacteria.

What is the rarest role of bacteria?
One rare role of bacteria is their ability to produce antibiotics. Some bacteria species can produce compounds that inhibit the growth of other bacteria, fungi, or even viruses. This natural antibiotic production is not common among bacteria, making it a rare and valuable trait.
What do bacteria have in common with the cells of the other living organisms?
Bacteria, like other living organisms, are made up of cells. Both bacteria cells and cells of other living organisms contain genetic material, have cell membranes, and exhibit functions necessary for survival such as metabolism and reproduction.
Why don't most other types of bacteria produce ulcers?
Most other types of bacteria do not produce ulcers because they lack the specific mechanisms and enzymes needed to disrupt the protective mucosal barrier of the stomach and cause damage to the tissues. Helicobacter pylori, the bacteria responsible for most ulcers, is uniquely adapted to survive in the acidic environment of the stomach and has specialized virulence factors that allow it to colonize the stomach lining and cause inflammation.
3 ways humans use bacteria?
Humans use bacteria in the fermentation process to produce products like yogurt, cheese, and sauerkraut. Bacteria are used in sewage treatment plants to break down organic matter and purify water. Some bacteria are used in biotechnology to produce insulin, antibiotics, and other pharmaceuticals.
