What the difference between S-Layer and EPS in bacteria?
538190
An S-layer is a membrane commonly found in gram-positive and gram-negative bacteria, as well as among Archaea. It is composed of protein and glycoprotein. \nEPS is extracellular polymeric substances

they r :\nsolid media (in which agar is added)\nliquid media (no agar added)\nsemi-solid media (agar added so that it is just semi-solid)\n\nright??\n\n[P.S - when do i get voted for "best answer"??]

ions are polar, so they don't mix with the non-polar lipid bilayer. there are protein channels for their transportation, and pumps and all that..

The same advantage it is to any bacterium. It's a thick walled cell that allows the bacterium to remain dormant in times of stress without dying.

usually you can see the colonies in the agar. they'll be kind of circular spots in the agar. then you can put them under a microscope and see what kind of bacteria it is.

same:   both have a lipid bi-layer membrane.  Both have Peripheral and integral membrane proteins.\n\nDifference:  single celled normally have cilia or flagella, single celled macrophage whereas multicelled normally don't.  Multicelled handle disease better.

eukarotic bacteria are unicellular; fungi can be multicellular whereas bacteria can not. Bacteria move themselves by means of a flagella unlike fungi which don't. Bacteria lack a nucleous and mitochondria unlike fungi. Many bacteria have differing cell walls from fungi. I believe the term used is peptidoglcoans, which describes the cell wall.

Non of the gram negatives,so the answer will not be E.coli or Pseu....\nendospores are produced by some gram positives like Bacillus,Clostridium and sarsina \nhope it works;)

Many of them oxidize H2S\n\nso its like water but using sulphur, thats why a lot of these bacteria are purple. \n\nheres an abstract on how they work, or at least will give you a general idea ans some examples!\n\nSeven strains of heterotrophic iron-oxidizing acidophilic bacteria were examined to determine their abilities to promote oxidative dissolution of pyrite (FeS2) when they were grown in pure cultures and in mixed cultures with sulfur-oxidizing Thiobacillus spp. Only one of the isolates (strain T-24) oxidized pyrite when it was grown in pyrite-basal salts medium. However, when pyrite-containing cultures were supplemented with 0.02% (wt/vol) yeast extract, most of the isolates oxidized pyrite, and one (strain T-24) promoted rates of mineral dissolution similar to the rates observed with the iron-oxidizing autotroph Thiobacillus ferrooxidans. Pyrite oxidation by another isolate (strain T-21) occurred in cultures containing between 0.005 and 0.05% (wt/vol) yeast extract but was completely inhibited in cultures containing 0.5% yeast extract. Ferrous iron was also needed for mineral dissolution by the iron-oxidizing heterotrophs, indicating that these organisms oxidize pyrite via the "indirect" mechanism. Mixed cultures of three isolates (strains T-21, T-23, and T-24) and the sulfur-oxidizing autotroph Thiobacillus thiooxidans promoted pyrite dissolution; since neither strains T-21 and T-23 nor T. thiooxidans could oxidize this mineral in yeast extract-free media, this was a novel example of bacterial synergism. Mixed cultures of strains T-21 and T-23 and the sulfur-oxidizing mixotroph Thiobacillus acidophilus also oxidized pyrite but to a lesser extent than did mixed cultures containing T. thiooxidans. Pyrite leaching by strain T-23 grown in an organic compound-rich medium and incubated either shaken or unshaken was also assessed. The potential environmental significance of iron-oxidizing heterotrophs in accelerating pyrite oxidation is discussed.

Respiration is much more efficient than fermentation and respiring organisms, including us, have come to dominate the earth. Fermenting organisms are restricted to niches where oxygen is lacking (or they are at an advantage) and suitable carbon sources exist. Again, the diversity of respiring microbes is vast, but they do have many things in common.\n\nATP is generated by ETLP involving a membrane system. \n\nThe energy yield from respiration is much higher than fermentation and the substrate often has all available electrons removed; it is fully oxidized.\n\nThe terminal electron accepter is inorganic. For aerobic respiration this is oxygen, but bacteria are also capable of using nitrate, sulfate, methane and others.\n\nSubstrates for respiration include\n\nOrganic molecules - Sugars, amino acids, nucleotides, organic acids, fats. Some microbes can even catabolize benzene or toluene. The point is, the list is large.\n\nInorganic - Certain groups of bacteria are capable of using an inorganic compound as their source of electrons. For example iron bacteria will start with Fe+2 and oxidize it to Fe+3. Sulfur oxidizing bacteria will take inorganic sources of sulfur (H2S) and oxidize them.\n\nProducts of Respiration tend to be highly oxidized.\n\nOrganic molecules are most often oxidized to CO2 and H2O. \n\nInorganics change to CO2, N2 and SO4-2

In Staphylococcus aureus the cell wall is ca. 40 nm wide.

yes, the insert disrupts the lacZ gene and so if you plate the bacteria with x-gal (a substrate to turn blue), the colonies that have the insert will remain white while the colonies that don't will stay blue. lacZ when uninterrupted allows the x-gal to be metabolized and turn blue

Bacteria do not reproduce sexually in the way that animals do, so there are no "male" and "female" designations.  The closest you would get is F+ and F-, where the fertility plasmid is present or not.  But back to your question, the flagella is in a similar location in all of a species of bacteria.

The Gram reaction is based on the structure of the bacterial cell wall.\nIn Gram-positive bacteria, the purple crystal violet stain is trapped by the layer of peptidoglycan which forms the outer layer of the cell.\nIn Gram-negative bacteria, the outer membrane prevents the stain from reaching the peptidoglycan layer in the periplasm. The outer membrane is then permeabilized by acetone treatment, and the pink safranin counterstain is trapped by the peptidoglycan layer.

If by morphology you mean "Gram-negative rod" then you'd get false positives.  All enterobacteriaceae are Gram-negative rods, but not all Gram-negative rods are enterobacteriaceae.\n\nColony morphology won't necessarily help a lot, either, as I don't think that there is a consistant enteric colony shape.
