When A. borkumensis bacteria use alkanes as their source of energy, each cell forms a biosurfactant (other sources of energy do not cause the bacteria to produce this biosurfactant). A biosurfactant is an extra layer of material forms along the cell membrane. The substances that make up the biosurfactant of A. borkumensis can reduce the surface tension of water, which helps with the degradation of oil. They are also emulsifiers, which further serve to break up the oil/water emulsion, making oil more soluble. A. borkumensis forms a biofilm (a wall of cells) around an oil droplet in seawater and proceeds to use biosurfactants and metabolism to degrade the oil into a water-soluble substance.[4]
Strains of bacteria are taken from oil and later isolated. The strains of bacteria are grown in a laboratory on a petri dish under controlled heating conditions.
Answer:
The development of bacterial strains with specific appetites can be done in the method described above. Alternately bacteria native to an area can be cultivated by adding nutrients to the soil which encourage some of the bacteria in the area to take up oil asa food. These will flourish as the oil is the most abundant food available and eventually represent the majority of the bacteria present.
How do scientists produce oil-eating bacteria?
By inducing mutations in bacteria
recombinant technology
carefully
Most bacteria produce asexually by binary fission. If sexually the produce by
Agar (a seaweed derivative)
Why dont most other types of bacteria produce ulcers?
archeabacteria and eubacteria
Inducing mutations in bacteria
Insulin-producing bacteria were commercialized in 1982.
Harnessing photosynthetic processes

Genetically modified bacteria can be used to produce. This is a transgenic bacteria.
Cyanobacteria or blue-algae are microbes that produce oxygen through the process of photosynthesis. Some scientists believe that these bacteria were the first to produce oxygen on Earth.
Yes. Bacteria do produce toxins. Usually gram positive bacteria produce exo-toxins and gram negative bacteria produce endo-toxins.
Human genes can be inserted into a bacteria and produce large numbers of human proteins on an industrial state!!

Bacteria in combination with organic material can produce methane gas. The addition of bacteria to heavy oil deposits to produce methane gas is new research, but it certainly looks promising. Bacteria does not create gasl on its own, but rather transforms the organic material into gas. I've included one link, where scientists claim that bacteria may be used to create oil, but I am not aware of any commercial applications. See links.
True in the 'manufacture' of Human Insulin - 'Humulin" genetically engineered bacteria are used to produce drugs and other chemicals that benefit humans.
Bacteria in the large intestine can produce important vitamins for the body. For example, some bacteria produce vitamin K from eating fiber. Some bacteria also produce vitamin D.
