Study Notes
- Bacteria play a key role in the nitrogen and sulfur cycles in ecosystems.
- Bacteria are used in various industrial processes such as food and beverage fermentation, vinegar production, and antibiotic production.
- Vinegar is produced by fermenting beer, wine, or cider with a special bacterium called Acetobacter.
- Sewage treatment relies on the action of microorganisms to oxidize organic matter present in sewage.
- There are two main methods of sewage treatment: percolating filter method and activated sludge method.
- Bacteria are used to produce insulin, human growth hormone, enzymes for washing powders, and human vaccines.
- Nitrogen fixation is the process of fixing nitrogen gas into forms other organisms can use.
- Ammonification is the process of breaking down proteins in dead organisms and animal waste, releasing ammonium ions.
- Nitrification is a two-step process of oxidizing ammonia or ammonium ions to nitrites and then to nitrates.
- Denitrification is the process of reducing nitrates to nitrogen gas, returning nitrogen to the air and reducing the amount of nitrogen in the soil.
