Escherichia coli and Staphylococcus albus Some bacteria’s require a certain amount of light in order to function properly and there fore survive. Escherichia coli is found in the gut and intestines of mammals. Staphylococcus albus is generally a skin dwelling bacteria Aim: To test whether the amount and type of light that the bacteria’s E.coli and S.albus are subject to causes changes in their growth rates and habits. To test whether the growth rates and habits of the bacteria’s E. coli

Staphylococcus epidermidis is one of the most prevalent microorganisms found on the human skin and in the mucous membranes‚ however‚ it is a typically overlooked bacterium because there is very little that is known about it. Though it is not as aggressive as its cousin Staphylococcus aureus‚ Staphylococcus epidermidis is the most frequent cause for nosocomial pathogens‚ especially among newborns‚ the elderly‚ and anyone who has a compromised immune system. These infections are usually associated

experiment two different types of bacteria‚ Escherichia coli and Staphylococcus aureus‚ were grown singly and mixed on four different types of agar in order to observe the varying morphologies within the colonies. Resulting data was analyzed to provide understanding of the use of differing culture media and conditions for bacterial growth. RESULTSFour different agar types were used in this experiment. The first (Nutrient) allowed for growth of both E. coli and S. aureus. The second agar used (MKL)

The Figure 4.20 shows the profile growth of Escherichia coli type K-12 which was cultured in 20 g/L of glycerol treated with supplements from a carbon source under anaerobic condition and the medium supplemented with 10 g/L of trypton. About 10% working volume of inoculums were added to the medium for the profile growth process. The effects on growth curves of strains of Escherichia coli were investigated by measuring the concentration of succinic acid produced and its optical density by using HPLC

This project’s purpose is to find the effects of UV light on Staphylococcus epidermidis‚ furthermore recognized as staph infection. Staph infection is an infection usually acquired on the skin that can promote fever‚ nausea‚ pain‚ boils‚ and can lead to MRSA‚ which can lead to death. Because there is no cure for staph infection‚ this experiment called for research on clinical trials. A clinical trial was established that used blue light therapy to delay and kill the growth of staph infection. Coincidentally

The Life of Escherichia Coli Escherichia Coli 0157:H7 bacterium can live in the intestines of cattle‚ therefore meat can become infected during slaughtering. You can contract this bacterium by eating undercooked meat‚ especially ground beef. Escherichia Coli 0157:H7 can also be contracted by eating contaminated fruits or vegetables‚ as well by drinking raw fruit juices or milk‚ or sewage contaminated water. Infection can also be spread via person to person. Escherichia Coli 0157:H7 can also

Through processes know as wet mounts and simple stains‚ observing living microorganisms through a compound microscope can generate a clearer understanding of their appearances and movements. Microorganisms are living things that for the most part cannot be seen through the naked eye. They live on and among humans‚ as well as plants‚ animals‚ and all that is a part of the Earth. Harmless as most seem to be to humans‚ microorganisms are an important relevance of study for human interest in varied perplexities

Transformation Of Escherichia Coli With pGLO Plasmid April 24‚ 2013 ABSTRACT: This experiment focuses on genetic engineering and transformation of bacteria. The characteristics of bacteria are altered from an external source to allow them to express a new trait‚ in this case antibiotic resistance. In is experiment foreign DNA is inserted into Escherichia coli in order to alter its phenotype. The goal of the experiment is to transform E. coli with pGLO plasmid‚ which carries a gene for ampicillin

Abstract The purpose of this experiment was to study the transfer of genetic information on plasmid F’lac by using Escherichia coli. Plasmid transfer was measured by using two different methods. The first one was by using selection and contraselection with three antibiotics: streptomycin(which was replaced by naladixic acid for the second part of the experiment)‚ampicillin and kanamycin and the second one by using a colour indicator ( X-gal). As significant results‚ the percentage of transfer for
