The Effects Of Electrical Current On The Bacterial Bacteria

THE EFFECT OF INCREASING THE CONCENTRATION OF DETTOL ANTISEPTIC LIQUID ON THE GROWTH OF E.COLI

From surgery to radium exposure to such extremes as radiation therapy, as doctors’ knowledge of the varying types of cancer, and the expansion of medical research regarding cancer has changed, so has the preferred method of treatment. Doctors and researchers dedicated to studying cancer have led to a greater understanding of cancer development; consequently the development of treatments and cures that are more effective, less harmful, have fewer side effects, and in some cases serve to prevent the spread of cancer.

The antibiotics will have different zones of inhibition on different bacteria. Also, a range of concentrations of the nutrients in the bacteria will change the bacterial growth.

This article explained how electricity was generated in the early 1900s. Burning coal in the city centers produced electricity and also helped to heat buildings. Only people near from the city were able to use electricity because there was not way to transmit the electricity to rural areas. After a long time coal plants started to grew and people were facing difficulties because the coal plants occupied space and they also produced pollution to the city. People decided to move coal plants to the outside of the city in that way people would not be affected, they started to use transmission wires to carry electricity. Even though they did not have the same efficacy to obtain electricity they were finding a way to improve it. At the beginning of 1970 technology began to improve, so many mass-produce engines were produce and they can be located in the middle of the population, also decentralized plants were used to recycle the wasted heat. After all these benefits of the new technology, industry decided to make some changes. Electric monopolies started to charge people for the use of electricity. Later on, congress tried to open competition in 1978 and some independent power companies started to develop one site generation. This article was focused in a research on how to build new power generation providing technology, capital costs and fuel prices. After all of this significant and dramatic changes in electricity, United States was facing problems because the power industry

Out of the all the antiseptics being used in this investigation the more well known antiseptics such as dettol and sudocrem will be more effective when stopping the growth of bacteria than natural antiseptics like lemon.

Microbial Fuel Cells use bacteria to convert waste into electrical energy. These bacteria break down almost any biodegradable organic waste including sewage and water waste and use it as fuel to generate power. Places like Penn State University and The Biodesign Institute in Arizona State University are already testing and improving this new alternative energy. According to Penn State University they have achieved in producing 1.5 watts per meter squared of amount of waste water taken in and believe that a large industrial plant will be able to produce near 0.8 watts per meter squared and will be able to support about 500 homes (9). This is a new technology that is being avidly researched, however it is not currently used in large

During the last decade, major progress has been made in the treatment of disease with radioisotopes. Treatments involving the use of medical isotopes are gaining momentum in the race against many types of cancer. FDA approved and highly promising therapies are doubling every 3 to 4 years. Some researchers predict that over 80% of cancer types should be treatable with

In this experiment, we wanted to investigate which surfaces in the school had the most bacteria, and we thought that the surfaces used more would have the most bacteria. For this experiment we used agar plates, cotton swabs and distilled water in order to see how much bacteria was on each surface. Cotton swabs were wet with distilled water and then the swabbed ws wied on a 2 inch space of the surface and twisted to cover the entire swab.once we swabbed the surface, we wiped the swab on the plate in a zigzag motion holding it upside down. The girls bathroom sink handle had 389 bacteria, and the boys bathroom by the football field had 0. We saw that places commonly used such as the bathroom sinks, door handles and railings contracted the most bacteria.

This allows it to interact with other atoms in many ways. This is very significant when Platinum is used in anticancer drugs for chemotherapy. Cisplatin is a Platinum based drug and is one of the oldest and most successful anticancer drug in the history of chemo prescriptions. The molecule structure of DNA is very important for the interaction of Cisplatin. It is a double-helix and is held together by building blocks, scientifically known as nucleotides. Through the bases of DNA, Platinum is then able to its job. The drug reacts in a displacement reaction. The chlorine atoms that are in our bodies are displaced by the aqua ligand, a coordination compound of metal ions and water, which is the displaced by the nitrogen in the DNA. The cisplastin then is left to interact with the DNA and creates two cross-link stands. Repairing mechanisms in the body then separate the cisplastin from the DNA which then causes the damage of the unhealthy cells. (Carmen Drahl 2017) this is shown in fig

I can draw from these results that as the chemotherapeutic drug concentration is increased the cell viability decreases. In HEPG2 the viability at the control was 100% but when the drug was added at concentration of 40µm the cell viability decreased to 2.62%. From these examples we can deduce that the chemotherapeutic drug added is successful in its use and that it is targeting the cancerous cells. The drug damages the genes present inside the cell line

In this experiment, each student was randomly assigned with a different species of gram- negative bacteria. The organism that I was assigned was Unknown #16. The identity of the gram-negative bacteria was determined to be Escherichia coli. The purpose of this report is to describe the various tests that helped develop a better understanding of the unknown microorganism in terms of the physiology, morphology, motility, and antimicrobic sensitivity it is characterized with. Indole production, hydrogen sulfide, and the colony morphology on the Eosin-methylene blue (EMB) plate, were the critical results that led to the conclusion that the organism was E. coli. In the indole production test, E. coli was one of two organisms,

This experiment is about bacterial growth. We will demonstrate a bacterial growth curve using a closed system. Bacterial growth usually takes up to 12-24 hours to get an accurate result so we will be monitoring this growth between two classes. We also used different methods to determine bacterial growth as well as a few different calculations. One way of receiving data is by using a spectrophotometer where we will record the absorption at a given time to create the bacterial growth curve. We also used the plate count method after performing a serial dilution to calculate the actual cell density at different times given. By using this method we can count the population number of the same given and see the maximum cell density

The main purpose of experiment eleven was to observe how different environmental factors affect the growth of microbes. We observed the growth in differing temperatures, salt solutions, as well as osmotic pressure.

The purpose of the two experiments was to determine the fundamental effects that temperature has on the growth and survival of bacteria. During the first experiment five different bacterial broth cultures of Escherichia coli, Pseudomonas fluorescens, Enterococcus faecalis, Bacillus subtilis and Bacillus stearothermophilus were individually incubated at temperatures of 5, 25, 37, 45 and 55°C for one week in an aim to distinguish the effect temperature has on growth and survival of the five different species. After one week they were observed for distinguishable changes by the turbidity showing an indication of bacterial growth, or the clarity an indication of no survival.

The effect of environmental factors such as temperature, osmotic pressure, oxygen concentration and pH on microbial growth and survival
