Ammonia Oxidizing Bacteria
The article I chose relates to the nitrogen cycle covered in the book and in class. My article is titled Nitrogen Fertilization Changes Abundance and Community Composition of Ammonia-Oxidizing Bacteria. I liked the research and believe that it is very thorough I also understand the importance of bacteria on soil health.

Shen, W., Lin, X., Gao, N., Shi, W., Min, J., & He, X. (2011). Nitrogen fertilization changes abundance and community composition of ammonia-oxidizing bacteria. Soil Science Society of America Journal, 75(6), 2198-2205. Retrieved from http://search.proquest.com/docview/909942088?accountid=15042

The effects of Nitrogen fertilization on the abundance and community composition of ammonia-oxidizing bacteria are influenced by agricultural practices and the topic is covered in this article. When soil is fertilized by humans there is a change in the certain types of nitrifying bacteria that are among the clusters in Ammonia-oxidizing bacteria. The increase of individual types of bacteria in the ammonia-oxidizing bacterial communities in soil are also influenced by the type of fertilizers either chemical fertilizers and organic manure type fertilizer. Mixtures of organic and chemical fertilizers had a synergistic effect on the rates and shift of the main nitrogen fixing bacterias, Nitrosomonas communis and Nitrosospira clusters. Ph of the soil also has an effect on the ammonia oxidizing bacteria community and their composition.

also touches on the effects that fertilizers have on farm soils and the gaps that chemical fertilizers can fill during the seasons and abundance of captured nitrogen.

In the laboratory incubation studies show a shift in bacteria abundance and community population after 16 weeks of of

    Then you get it when you eat the plants or if you also eat animals you Nitrogen from the meat also. These bacteria in the root nodules have an enzyme called ___nitrogenase____ that helps them split the Nitrogen molecules into other forms. 6. The process the microbes go through to break the mainly toxic ammonia molecule into __nitrite__ (NO2- ) and ___nitrate__ (NO3-) is called ___nitrification__. 7. When these smaller molecules are taken up into plant tissue the term is __Assimilation__. 8. When decomposers (the microorganisms that do most of Earth’s recycling) break down decaying organic matter and waste depositing it back into Earth to be used gain this is called ___Ammonification____. 9. The term that names the process by which Nitrate or ( _ NO3-_ ) is converted back into atmospheric Nitrogen (N2) is __Denitrification___. 10.

    Microorganisms are plentiful and widespread in the environment. In this lab, we undertook to determine the differences in the agars being used and the different colony count observed. After taking four different samples of microbes from the environment and swabbed them in two different plates one with nutrient agar and the other with sabouaud dextrose agar. After the microbes had incubated for 48 hours no results were discovered from the swabs we had taken from the environment. This lab further investigates the different swabs from the environment other group got and the different results discovered from the agars being used and the colony count observed.…

    Nitrogen is the major component of earth's atmosphere. It enters the food chain by means of nitrogen fixing bacteria and algae in the soil. This nitrogen which has been fixed is now available for plants to absorb. These types of bacteria form a symbiotic relationship with legumes. These types of plants are very useful because the nitrogen fixation enriches the soil and acts as a natural…

    At the beginning of the semester, samples of bacteria were obtained from various sources. Two bacterial colonies were isolated from plates that were incubated in the lab and these bacteria became the basis for this project. The bacterial cultures were maintained and used for various physiological, cultural, and biochemical tests and observations over several weeks. The purpose of culturing bacteria over half the course of the semester was to learn various techniques used in microbiology labs and to subsequently utilize those techniques for the purpose of identifying the bacteria. The data, once compiled, was then used to determine the possible identity of the unknown bacteria based on the information found in Bergey’s Manual of Systematic…

    After WWII, the government found itself with a tremendous surplus of ammonium nitrate. Ammonium nitrate is the main ingredient for fertilizer, and bombs. This fertilizers that big industrial farms use destroy the fertility of the soil and damage the root system setup by the plants around the area. They can also drain into rivers and wipe out a species. DDT, that pesticide almost wiped out the Bald Eagle population. These pesticides and fertilizers have destroyed insects and nitrogen that help plants grow. Instead we use lab produced fertilizers to help the plants grow. These pesticides and fertilizers damage the ecosystems around them and our dangerous not just to plants and animals to but they are also damaging our environment. Pesticides and fertilizers are not the only thing that destroy soil fertility and the ecosystem around…

    To understand this experiment you need to understand the basic growth of plants. This experiment might be interesting to the scientific community to see how nitrogen fertilizer contributes to the growth of plants and, with further testing beyond our experiment, how it chemically affects growth. The general public might find this experiment interesting because, they want to produce good quality crops in the shortest amount of time, and fertilizers may enhance the growth of plants. The article discussions allowed me to see further into the experiment and helps better understand why certain things are occurring in the…

    This lab experiment serves as a model for community succession using bacterial colonies as the model. A bacterial colony grows from a single bacterium and is composed of millions of cells. Each colony has distinctive colony morphology: size, shape, color, consistency, and color. Community succession is a phenomenon observed in the organizational hierarchy of all living organisms. Community succession is not limited to bacterial colonies, but spans the entire community of life. As the community grows, it changes the environment it inhabits, and the resulting community is different than at the start. As community succession occurs in bacterial colonies pH, odor, color, and consistency changes take place. In this experiment, four different milk age samples, fresh, 24 hour old, 4 day old, and 8 day old milk, will be prepared on different sets of agar plates that will be diluted to different levels for optimum bacterial growth and measurement.…
