Abstract. The experiment provided evidence of microorganisms in aerobic compost. 18 buckets were set up with three different trials of compost, wet, dry, and moist. Although microorganisms were present they were too small to be identified and also conditions in the experiment were not stable enough to maintain life. Due to this we were not able to make any definitive decisions on whether our hypothesis was supported or rejected.
Introduction
Compost is used for many different reasons across the world today. It is a way to breakdown waste, used for gardens, creates beneficial bacteria and fungi, as well as allows the human population to recycle (EPA, 2012). Compost itself is not hard to make and can produce many different types of microorganisms; especially bacteria (Diaper, 1994). The microorganisms will begin to eat away at the living organic matter until it completely dies then new organic matter must be added in order to keep the cycle going, and the microorganisms alive. As the cycle continues the population also continues to grow and the organisms in the compost will begin to become more complex. Since the compost is a cycle as the compost itself matures the microorganisms inhabiting it will as well. In order to monitor how mature compost is, one of the best and easiest ways are to measure the pH (Boulter-Bitzer, 2006). We expected to see the largest population size in moist compost and smaller population sizes in both wet and dry compost.
Materials and Methods
Setting up the experiment. First 18 buckets were needed in order to maintain the compost. All buckets needed to be of similar size, and each needed to have air holes poked into the side for proper ventilation. 6 of the buckets were maintained as the dry compost, there was no water added to the compost throughout the entire experiment. 6 of

    I then prepared 4 dampened similar sized paper towels that were placed inside of the pots to prevent the escape of the red wiggler earthworms. I poured the soil evenly into the 3 pots until the soil filled ½ of the pot and patted down the soil evenly. Next the 2 mesh strainers were used to shift through the soil that the red wriggler worms were being contained in, the small mesh strainer was used to gather the dirt from the container and then the dirt was poured into the big mesh strainer and shaken until a worm was found, if not another scoop of dirt was shifted through until in total 10 worms were retrieved. 5 worms were put into the experimental nitrogen pot and the other 5 were distributed to the experimental phosphorus pot. Once all the worms had burrowed into the soil the rest of the pots was filled until the…

    Decomposition is the breakdown of organic material into its smaller molecules and elements. (This term is generally considered as a biotic process but one may find it also used to describe an abiotic process, e.g., due to weathering.) The decomposing organisms may use the release of elements for nutrients and by breaking apart the carbon-carbon bonds in organic matter this can release energy for them. These smaller molecules and nutrient elements may also become available for use by the primary producers (i.e., plants and phototropic microorganisms). Decomposition is an important step in the food chain and contributes to the nutrient cycling within an ecosystem. Most of the organic matter in an ecosystem ultimately passes through the decomposer subsystem.…

    This experiment focused on metabolism and biochemical tests. The goal of performing these tests was to differentiate microbes from one another and to compare how metabolic and biochemical processes differ from species to species. The tests performed include: the Fermentation of Sugars Test (sucrose, glucose, and lactose), the Urease Test, the Fermentation of Lactose Test, the Sulfide Indole Mobility (SIM) Test, the Nitrate Reduction Test, the Protein Hydrolysis Test, the Catalase Test, and the Cytochrome Oxidase Test. The microbes that were tested during this lab were: Escherichia coli, Bacillus cereus, the unknown, Proteus vulgaris, Staphylococcus epidermis, Enterobacter aerogenes, the control, and Pseudomonas fluorescens. The microbes tested during these various tests were looking for which would: reduce sulfur/produce sulfate, produce indole, or possess motility, reduce nitrate, and contain protease, catalase and oxidaase.…

    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.…
