Q. What is the function of the endospore to bacterial cells?
Asked by The Goddess - Wed Sep 20 20:44:28 2006 - - 2 Answers - 0 Comments
A. Bacteria form endospores when they have some sort of stress. The endospores are pretty resistant to all sorts of things that would normally kill the bacteria (such as heat or low food). It's the bacteria's way of making sure its genetic material survives through the tough times.

What is malachite green used for while doing an endospore stain?
Q. 1) why do we autoclave while doing an endospore stain? 2) why do we use safranin while staining 3) why do we use iodine?
Asked by ashley D - Sun Sep 27 01:31:47 2009 - - 1 Answers - 0 Comments
A. 1. Endospores are resistant to staining and destruction. The heat of the autoclave is used to to help the endospore uptake the green stain. 2. It is used as a counterstain (it is the contrast agent that do not hold on to the primary stain) 3. It increases the cellular components affinity for the crystal violet stain.

Q. what prevents the cell from appearing green in the finished endospore stain?
Asked by Bridget - Wed Oct 1 01:04:51 2008 - - 1 Answers - 0 Comments
A. Endospores strongly resist application of simple stains or dyes and hence appear colourless in Gram-stain preparations. However, once stained, endospores are quite resistant to decolorization. This is the basis of the Schaeffer-Fulton staining method. Principle of the Schaeffer-Fulton staining method: Heat is used as a physical mordent which weakens the spore walls allowing the primary stain (malachite green) to penetrate the endospore. At this point, both, the vegetative cell and the endospore are stained green by Malachite Green (primary stain). After being stained with Malachite Green the slide is allowed to cool so the spore walls will harden again. The slide is then washed with deionized water. The dye is trapped in the endospore… [cont.]

A. A. plasmids are genes that are found outside the bacteria's main chromosome(s). the chromosome contains all the genetic information needed for the bacteria to function, B is wrong. it WILL be able to survive in its normal environment (unless that environment happens to be filled with antibiotics. C. i dont know why it would lose base pairs... plasmids are not part of the chromosome D. cell wall would be part of the genetic code found in chromosomes E. it isnt missing a chromosome...its missing a plasmid so your correct answer is A. plasmids tend to carry antibiotic resistant genes. bacteria can then swap plasmids with each other, increasing their resistance to antibiotics. something like "bacteria sex" =P.

A. well coccus shaped bacteria look like little balls, and endospores are shaped like balls, WTF? how can we tell the difference?!?!? Although both are spherical in shape, they have distince differences. When looking at microscopy, a bacteria will have a dark region, aka the nucleus - where the DNA/RNA is held. On the other hand, when you look @ endospores, there may be a nucleus, but no dark region. Rather it will look like white balloons blown up within one another. Hope it helps -- Just my 2 cents :)

A. Endospores are dormant cells that are very resistant to heat. When home-canning, or in foods that are pasteurized, spores may not be killed, and can germinate either in the food or in the body when consumed. Botulism is caused in this way. The bacterial spores germinate in the canned food, and produce botulinum toxin. You eat the food, and get botulism.

A. Purpose: The endospore stain is a differential stain which selectively stains bacterial endospores. How it works: Bacterial endospores are metabolically inactive, highly resistant structures produced by some bacteria as a defensive strategy against unfavorable environmental conditions. The bacteria can remain in this suspended state until conditions become favorable and they can germinate and return to their vegetative state. The primary stain applied is malachite green, which stains both vegetative cells and endospores. Heat is applied to help the primary stain penetrate the endospore. The cells are then decolorized with water, which removes the malachite green from the vegetative cell but not the endospore. Safranin is then… [cont.]

A. Formation: When a bacterium detects environmental conditions are becoming unfavorable it may start the process of sporulation, which takes about eight hours. The DNA is replicated and a membrane wall known as a spore septum begins to form between it and the rest of the cell. The plasma membrane of the cell surrounds this wall and pinches off to leave a double membrane around the DNA, and the developing structure is now known as a forespore. Calcium dipicolinate is incorporated into the forespore during this time. Next the peptidoglycan cortex forms between the two layers and the bacterium adds a spore coat to the outside of the forespore.
