What specific conditions does Bacillus subtilis need to be in to form endospores?
Q. This is for a science experiment. I need to know specific conditions such as temperature and whatnot. Anything would be of great help!

A. Most Bacillus species are versatile chemoheterotrophs capable of respiration using a variety of simple organic compounds (sugars, amino acids, organic acids). In some cases, they also ferment carbohydrates in a mixed reaction that typically produces glycerol and butanediol. A few species, such as Bacillus megaterium, require no organic growth factors; others may require amino acids, B-vitamins, or both. The majority are mesophiles, with temperature optima between 30 and 45 degrees, but the genus also contains a number of thermophilic species with optima as high as 65 degrees. In the laboratory, under optimal conditions of growth, Bacillus species exhibit generation times of about 25 minutes. Bacillus species are easily isolated and… [cont.]

What is the difference between inclusions and endospores?
Q. Their role is identical!
Asked by rocken_heimer - Wed Sep 12 15:10:36 2007 - - 1 Answers - 0 Comments
A. I dont know if youre talking about bacteria, but I wouldnt say they are identical in bacteria. endospores are produced by some bacteria when they are found in harsh environments or stress in order to survive those conditions for a long time. inclusion bodies are produced by bacteria when the protein produced (from recombinant DNA) is for some reason "insoluble"and many times misfolded, in which a bunch of this protein kind of clumps together forming inclusion bodies.

why wont you get food poisoning from eating fresh fruit with endospores of clostridium botulinum?
Q. and why might you get food poisoning if you ate home-preserved fruit that spoiled?
Asked by hugznkizzez101 - Fri May 16 18:08:22 2008 - - 3 Answers - 0 Comments
A. The answer regarding the acidity of fruit is partly correct. Clostridium botulinum spores will not hurt a grown up It can kill a baby.because a babies stomach does not produce enough acid to kill it. They are found in the soil. They release a toxin when they are in an airless environment such as a closed can or a puncture wound. It is a nerve toxin. It is found in improperly canned vegetables that are not acidic or heated hot enough (pressure canner) Heat will kill the toxin so if the product is boiled it will destroy the toxin. Home canned fruit may spoil although fruit will not contain botulism because of acidity.

Asked by Joseph - Mon Aug 17 23:13:10 2009 - - 1 Answers - 0 Comments
A. Bacterial endospores are dormant structures formed by certain ( Gram-positive ) bacteria during unfavorable conditions. A protective outer covering encases dna and a small amount of cytoplasm. Endospores germinate as soon as conditions permit. Endospores are resistant to ultraviolet and gamma radiation, desiccation, lysozyme, temperature, starvation, acids and chemical disinfectants.

if spores are so advantageous, why do all bacteria not produce endospores?
Q. As a trait that seems only advantageous why would others not have it. Spores allow some bacteria to survive where others would not. So wouldnt it only help to develop a spore?
Asked by xrcjapan4 - Thu Apr 17 18:36:35 2008 - - 2 Answers - 0 Comments
A. Just because a trait is advantageous doesn't mean an organism will evolve that particular trait. Bacteria can evolve other traits that protect them from environmental stress as well as endospores. The only matter of importance is that the organism be able to survive a particular stress, not that it simply try what has worked for others, as that would be difficult in evolution.

Asked by Summer<3 - Tue Mar 4 16:04:50 2008 - - 1 Answers - 0 Comments
A. An endospore is a dormant, tough, and non-reproductive structure produced by a small number of bacteria from the Firmicute phylum. The primary function of most endospores is to ensure the survival of a bacterium through periods of environmental stress. They are therefore resistant to ultraviolet and gamma radiation, desiccation, lysozyme, temperature, starvation, and chemical disinfectants. Endospores are commonly found in soil and water, where they may survive for long periods of time. . . :-)

A. Two reasons: 1) spores are more difficult to kill than vegetative cells (in terms of needing higher heat or more powerful cleaning agents) and 2) they can remain dormant on surfaces, devices, parts of machines for long periods of time until the right conditions are met and then the spore becomes a vegetative cell again (and thus can cause an infection or spoilage of the product).

Q. Explain how endospores are important in disease transmission and also in the food industry.
Asked by pixiedusk13 - Wed Sep 20 10:51:55 2006 - - 3 Answers - 0 Comments
A. Endospores are hardier than regular bacterias, and would survive the process used to kill bacterias (boiling for example). Therefore even if you process food as you should, endospores would still "survive" and could return to bacterial form in the human body and cause disease. To eliminate endospores you need more aggressive sterilization methods (I can't recall of the top of my head if autoclaving is enough to kill endospores, but I believe is not. I believe sterile filtration will eliminate endospores).Endospores can also be transmitted through the air (anthrax in the letters were sent in endospore form). (PS: Are you ever going to read your text book)

A. staining technique is the Schaeffer-Fulton method, in witch the stain is actually steamed into the endosproe: First the bacteria is smeared on a slide and fixed to the surface with heart, then primary stained with malachite green then heated with steam for a few minutes to force the stain past the protein coat, then they are washed with water (decolorized), then the bacteria is counter stained with safranin red (counterstaining), then the cells are rinsed one last time with water and then resolved under the microscope.

Asked by Tiya O - Thu Apr 24 10:16:59 2008 - - 1 Answers - 0 Comments
A. Endospores are not considered to be a form of reproduction because it is the protecting of DNA but it does not multiply the number of organisms that you have. The cell cannot reproduce in spore stage, therefore it is benenfical for the cell to remain in a nonspore phase when it is possible to do so. This way it can make additional copies of itself.
