What Are Some Advantages And Disadvantages Of The Serial Dilution Agar Plate Technique The volcanoes also form new, extremely rich soil as in the Hawaiian Islands. In other areas where plates meet the plates push together and form non-volcanic mountains, providing variety in planetary ecosystems and species.

These gases probably formed our Nitrogen-Oxygen-Co2 atmosphere that is ideal for supporting life on our planet. Because of the volcanoes formed by the subduction zones (where one tectonic plate falls and slides under an adjacent plate) gases from deep inside the earth are released. For example, the San Andreas fault, which runs under San Francisco, is actually a place where the North American and Pacific plates meet, and a little slipping along that fault line caused the great San Francisco earthquake in 1906. Of course, there are still problems where the plates meet. This was a huge volcanic eruption in Indonesia in 1883 that affected weather patterns all over the world. Advantages And Disadvantages Of The Serial Dilution Agar Plate Techniques For a more dramatic example, consider Krakatoa. It's a geyser - a sort of natural steam valve that releases the pressure of very hot subsurface water.

When fixed amounts of this dilution series are mixed with an appropriate agar and incubated, then different numbers of colonies will be obtained.įor a small example, consider 'Old Faithful' in Yellowstone Park. 1 ml added to 9 ml gives a 10-fold dilution 1 ml added to 99ml gives a 100-fold dilution. Serial dilution involves repeatedly mixing known amounts of source culture with (sterilised) liquid. Repeat the flaming and spreading for each of the remaining five plates. Spread the 0.1 ml inoculum evenly over the entire surface of one of the nutrient agar plates until the medium no longer appears moist. Three dilutions (10-5, 10-6, 10-7) to duplicate nutrient agar plates, and label the plates. If the plates didn't move, the pressure from trapped heat would cause violent explosions. The idea behind 'plate tectonics' is that the surface of our Earth is composed of large 'plates' that move on a molten base.
