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!
Asked by dragon_hype - Mon Dec 11 01:09:10 2006 - - 2 Answers - 0 Comments

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.

What's the difference in dyes when staining endospores?
Q. What would happen if you used safranin as the primary stain and malachite green as the counter stain when dying a spore, instead of the other way around?
Asked by Ryan - Wed Jul 1 19:55:07 2009 - - 1 Answers - 0 Comments

A. If the heat can drive safranin into the endospore just like it does malachite green, then the spores would be pink and the rest of the cells would be green.

Is it common for bacteria to form endospores?
Q. If not, which bacteria form them?
Asked by BeautifulDevil - Sun Feb 8 11:32:57 2009 - - 1 Answers - 0 Comments

A. An endospore is a dormant, tough, and non-reproductive structure produced by bacteria from the Firmicute phylum, ensuring survival through periods of environmental stress. The preponderance of bacteria--including all gram-negative bacteria, the Actinobacteria phylum, and the Tenericute phylum--do not form endospores. The following bacterial genera all form endospores: Acetonema, Alkalibacillus, Ammoniphilus, Amphibacillus, Anaerobacter, Anaerospora, Aneurinibacillus, Anoxybacillus, Bacillus, Brevibacillus, Caldanaerobacter, Caloramator, Caminicella, Cerasibacillus, Clostridium, Clostridiisalibacter, Cohnella, Dendrosporobacter, Desulfotomaculum, Desulfosporomusa, Desulfosporosinus, Desulfovirgula, Desulfunispora, Desulfurispora,… [cont.]

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).

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.

A. Capsule is a layer outside the cell wall of bacteria. - considered as the virulence factor as it enhances the ability of the bacteria to cause diseases. - prevents phagocytosis. - Protects from the dessication (state of extreme dryness). - Exclude bacterial viruses and detergents. Endospores are dormant, tough non reproductive structures produced by some genus like Bacillus, Clostridium etc.These are metabolically inactive and wait for the environment to become favourable. Once the favourable condition arrives it will germinate and vegetative cells can grow and thrive.Endospores are produced by a process known as sporulation. This process takes around 15 hours. The endospores can possibly survive thousands of years. Functions -… [cont.]
