Microbiology
Black carbon (BC), a carbon accounting for much of observed global warming to date, negatively affects human respiratory health. Thus, the purpose of this experiment was to determine the eff…
Microbiology
Fourth Award
The purpose of our experiment was to devise an effective yet cost-efficient means of killing microorganisms in drinking water. We created a self-sufficient attachment to Hippo Roller pushabl…
Microbiology (inferred)
Benzoic acid is a common phenolic phytochemical found in the natural environment. This phenol has been found to increase the susceptibility of resistant microbes, making it more feasible to…
Microbiology (Medical) (Junior Division Only)
First Award
Objectives/Goals Our experiment seeks to find a different way to solve the problem of antibiotic resistant bacteria, or superbugs, by using bacteriophages. We look at the effect of T4 coliph…
Microbiology (General)
Objectives/Goals The effects of carbon dioxide pollution, forest fires, and industrial chemical pollution on soil microbes are likely to be frequent in Southern California. To investigate wh…

Third Award
The first observation of Xanthomonas vasicola pathovar vasculorum, commonly known as bacterial Leaf Streak being in the United States occurred in Nebraska. As of August 2016, was identified…
Microbiology (inferred)
The question tested in this experiment is “How will the essential oils of basil and oregano affect the growth of Xanthomonas vasicola pathovar vasculorum?”. Bacterial Leaf Streak is caused b…
Microbiology
Third Award
Antibiotic misuse has caused bacteria to evolve resistance, raising the potential for widespread, devastating health crises. Novel therapeutic alternatives to antibiotics seek to target viru…
Microbiology
Third Award
The gut microbiome plays an essential role in human health. Sugar substitutes and food preservatives were tested for their effects on the microbiome, specifically their effect on the growth…
Microbiology (General)
Objectives/Goals The study will be conducted to evaluate how temperature affects E. Coli responsiveness to ampicillin. The key variable of this experiment is the temperature of the environme…
Microbiology (General)
Objectives/Goals The objective of this study is to test the validity of the Five Second Rule. This rule states that food dropped on the ground will be safe to consume and not covered in germ…
Microbiology (Medical) (Junior Division Only)
Objectives/Goals This project is about finding out if the extract of guava leaves can kill yeast, the fungus, which at times, becomes pathogenic. The extract of guava leaves is supposed to c…
Microbiology
Fourth Award
Helicobacter pylori is a persistent bacteria with defense mechanisms against the stomach’s acidic environment, allowing it to predominate the lining of the stomach. It affects approximately…
Microbiology
The purpose of doing this project was to try to answer a previous question created by a former science fair project. The question was to find out if inhibition could be created by herb mold…
Microbiology
According to the United States Department of Agriculture (U.S.D.A.) Microbial Standard for a high-quality grade A Pasteurized Product, a total colony count does not exceed 20,000 c/ml. Durin…
Microbiology
Five million gallons of formaldehyde are used in the funeral industry annually. Formalin based products are designated biohazards and carcinogens. To reduce groundwater pollution, natural, u…
Microbiology (inferred)
Pulmonary infections involving Pseudomonas aeruginosa (PA) are a complication faced by cystic fibrosis (CF) patients. Acidified nitrite (NaNO2) has been shown to be an antibacterial agent ag…
Microbiology (General)
Objectives/Goals My hypothesis is that specific endothelial cell membrane proteins called tetraspanins are necessary for C. albicans to invade endothelial cells, and my goal was to discover…
Microbiology
This project was conducted to find more information on the relationship between Bactrocera xanthodes (Pacific Fruit fly) and Artocarpus altilis (Breadfruit). The project is divided into two…
Microbiology
The purpose of the research was to determine if temperature had a significant effect on the zone of inhibition produced by the bacteria Pseudomonas protegens against the fungus Pseudogymnoas…
Microbiology (Medical) (Junior Division Only)
Objectives/Goals It has been suggested that yeast growth has important similarities to cancer growth. In this project I considered the effect of apple cider vinegar on yeast growth, with the…
Microbiology
The purpose of this project is to see if silver nanoparticles and/or silver nitrate can cause zones of inhibition in MSSA-23 and MRSA-9. Based of the results and a literature review, determi…
