Exercise 5 Introduction: Many different species of bacteria look similar under the microscope and also have the same staining results (ex. Gram stain). To be able to differentiate between the different species‚ one can look at the metabolic differences (fermentation)‚ as well as the environmental condition differences (temperature‚ pH‚ oxygen requirements). Being able to manipulate these conditions in a controlled environment can help to correctly identify the exact bacteria. Different media

The Nitrogen Cycle Nitrogen fixation Atmospheric nitrogen must be processed‚ or "fixed" to be used by plants. Some fixation occurs in lightning strikes‚ but most fixation is done by free-living or symbiotic bacteria. These bacteria have an enzyme that combines gaseous nitrogen with hydrogen to produce ammonia‚ which is then further converted by the bacteria to make their own organic compounds. Conversion of N2 The conversion of nitrogen (N2) from the atmosphere into a form readily available
