The applications of Bt corn are to produce a better quality corn that resists pests and parasites and will yield larger crops even in poor environmental conditions. The Cry1AB protein or Bt delta endotoxin located inside the Bt corn, is what is used to kill off Lepidoptera larvae, specifically the European corn borer, as they hatch and begin to feed on the plant as the protein is made by the plant in the tissue where these feed at. The Cry protein acts as a synthetic insecticide and is not…

I started with the gram negative bacillus by performing the nitrate reduction test and the urease test. I chose these two tests because I knew that a positive urease test would indicate that the gram negative bacillus was P. rettgeri, but this test came back negative after I performed two just to make sure that the results were accurate. Also, the nitrate reduction test could have indicated that the gram negative bacillus was P. fluorescens, but the test result was positive after…

To start with, look at the effectiveness of Antibacterial Hand Soap, against Bacillus and E.Coli. As it was stated, Bacillus is gram positive with spores and E. Coli is gram negative with no spores. But the hand soap was the most effective towards both. The reason behind this is because it contains the active ingredient Triclosan. Triclosan is a broad…

observation only while hanging drop is more complex technique but longer-term observation and more reliable observation of mortility. In this experiment, this two technique has been used to determine the mortality of bacillus sp. and moina micrura sp. From the result, we can see that bacillus and moina is moving when using the hanging drop technique while death when using the wet mount technique. This prove that hanging drop is the best technique to be used in this…

conclude that the hypothesis is rejected. This experiment can be taken in other directions. There are other factors that affect enzymes, such pH and salinity. In what way would pH affect enzymes? Not only can optimal temperatures be explored for Bacillus licheniformis and Aspergillus oryzae amylase, but for other enzymes from other organisms as well. How would the optimal temperature for an enzyme from a human, a mammal (warm-blooded), compare to the optimal temperatures for an enzyme from a…

Anthrax is a highly infectious disease that normally affects herbivores (livestock) and unfortunately may also spread to humans through inhalation, ingestion or any sort of skin contact of the bacterium, Bacillus anthracis. Bacillus anthracis (B. anthracis) is a gram positive spore forming bacterium that invades the human body and leads to various symptoms of Anthrax, depending on how virulent it has become. These symptoms include; swollen neck glands, bloody diarrhoea, vomiting blood, extreme…

Anthrax isolated case Anthrax is caused by the bacterial spore Bacillus anthracis. Bacillus anthracis’s characteristic spore allows it to live dormant for many years without desiccation before becoming active when exposed to water. It occurs naturally and can be found on vegetation and in many products made form animals. One method of contracting anthrax is inhalation. This has been known as a prevalent pathology of the disease among infected wool workers and hide tanners. It has also been…

Anthrax is a disease caused by the microorganism Bacillus anthracis. This primary pathogen is a zoonotic, aerobic, spore-producing bacillus which is gram positive when tested under a microscope1-4. It is particularly dangerous because of its hardy spores which can survive despite exposure to higher temperatures, light, and multiple disinfectants3. Once the bacteria are picked up by grazing herbivores, the spores begin to germinate and become virulent. As the bacteria continue to develop in the…

that the bacteria were pink, meaning that the bacteria are gram negative. I also recognized that the bacteria were rod shaped therefore they were bacillus. I also noticed that the arrangement appeared to be single celled. I also put the bacteria on a streak plate. On the second day, I did another gram stain and the bacteria were again pink and bacillus or rod shaped. I also observed the bacteria on a nutrient agar plate and noticed that the bacteria were light white almost clear color bacteria.…

multi-surface cleaner. Although the inhibition area for the blue paper is not in an easily calculable shape, its inhibition area covers almost half of the area inside the plate–similar to tetracycline. In conclusion, the scientists can infer that the Bacillus bacteria is more sensitive to the multi-surface cleaner than sanitizer. (Concept) Described previously, antibiotics and disinfectants are used to kill and inhibit bacterial growth but how they go about the process and its effectiveness…
