Document Summary

In agriculture, microbes are involved in n xation. In waste management, they are used to break down waste materials in land lls. They are used for familiar culinary purposes (such as making wine, bread and cheese). Animals use it to digest cellulose from plant products. Plants need microbes as well one of which include algae. However, antibiotics can kill commensal (good) bacteria inside the stomach. Much of the oxygen available to us comes from aquatic microbes. Microbes are able to recycle phosphorous, oxygen, sulfur and nitrogen. There are 10 bacterial cells for every one cell. Turning inorganic molecules such as n and co2 into organic compounds such as amino acids and nucleic acids. They are ultimately responsible for atmospheric o2 (cyanobacteria-aquatic microbes) Microbes are intimately involved in waste breakdown(garbage & sewage treatments) Food production (wine, bread, and cheese production for example) -> yeast is necessary for bread production(fermentation) and for ethanol. -> penicillin and insulin are derived from microbes.

Microbiology Unit 2 Applied and Environmental Assignment Part 1:

Identify Nutritional requirements from Chapter 6 & 14 (and review from chapters 1 & 2)

1. Determine which of the 4 macromolecules require the following elements:

a. Carbon: carbohydrates___ lipids___ proteins___ nucleic acids___

b. Nitrogen: carbohydrates___ lipids___ proteins___ nucleic acids___

c. Sulfur: carbohydrates___ lipids___ proteins___ nucleic acids___

2. The essential elements mentioned above are cycled through cells and the earth in biogeochemical cycles like the carbon cycle, the nitrogen cycle, and the sulfur cycle. Select the correct answer and fill in the blanks to summarize these cycles:

a. Carbon dioxide is taken in from the atmosphere by [autotrophs/heterotrophs] and converted to glucose through carbon ________________. When heterotrophs eat autotrophs they catabolize glucose to make ATP through __________________ and waste carbon is released as ___________.

b. There is plenty of nitrogen available in the atmosphere but it is not accessible to organisms because it is in the form of Nitrogen gas (N2). N2 is fixed by [bacteria/plants/animals] and converted to ammonia (NH3.) NH3 can be used by [bacteria/plants/animals] to build their cells. Next, by consuming food with amino acids, [bacteria/plants/animals] can get access to nitrogen for their own cellular needs.

c. There is also a good quantity of sulfur in dirt, rocks, and the atmosphere. Sulfur cycles between H2S => S0 => SO4 => SH groups in Proteins => back to H2S. Using _________________ respiration, anoxygenic photosynthesis, and chemolithoautotrophy [bacteria/plants/animals] convert H2S and S0 to SO4 which is taken in by [bacteria/plants/animals] and used to build their cells. When [bacteria/plants/animals] eat plants they take in essential amino acids containing sulfur and recycle these to make their own proteins.

d. _________________ break down waste and dead organisms and recycle nutrients back into the cycles.

*The C and N are summarized here: https://youtu.be/2D7hZpIYlCA and https://youtu.be/leHy-Y_8nRs

3. Identify the main metabolic classifications:

A microbe that makes its own food by taking carbon from CO₂ in the atmosphere and its energy from sunlight
A microbe that makes its own food by taking carbon from CO₂ in the atmosphere and its energy from reduced inorganic chemicals
A microbe that eats other organisms to get organic carbon and energy
A microbe that uses organic carbon from others but energy from sunlight

Discuss how we can put microbes to work to facilitate our lives: from keeping our landscape clean to making delicious food and beverages.

Recognize the importance of microorganisms in water and sewage treatment plants.

Describe food Microbiology, focusing on both preventative infection methods and the implication of specific microbial taxa in food preparation.

Describe the employment of microorganisms in industrial Microbiology.

Putting bacteria to work	Microbial fuel cell
Industrial microbiology biotechnology	Microbes in health care
Microbial taxa	Biotechnology and bacteria

Create a five-to-seven page essay summarizing various ways in which we employ microbes to our advantage. Think about their use in the food industry, waste management, health care, and conversion of waste product into fuel. Which of these applied Microbiology fields is of interest to you and has the potential for further development in your opinion?

Why is it likely that microbes evolved the production of antimicrobial compounds, considering the use of antibiotics in medicine is less than 100 years old?
