Food Technology

Bacteria are very useful in food production. In the production of cheese, lactic acid bacteria which include lactobacillus and lactococcus, are used together with yeast and mold in the production. Bacteria are also used in the fermentation of food which is beneficial to health and also useful in the preservation of foods.

What role do bacteria play in regulating Global Ecosystems?

Bacteria break down dead organisms and waste to release nutrients. This is the process of decomposition where chemicals such as carbon, phosphorous, and nitrogen are released. They also play a significant role in nutrient cycling which is a product of decomposition. They recycle the elements that make up the living system more specifically the process of photosynthesis where organisms take up carbon dioxide and convert it into organic material.
