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

CHAPTER I INTRODUCTION Background of the Study Early liquid hand soaps were made primarily for hospitals‚ restaurants and public facilities where regular hand washing was required. The original soaps were thicker and required a particular type of pump dispenser to deliver the product. The dispensers were expensive in spite of the fact that they clogged easily and were in constant need of repair or replacement. This combination of problems kept liquid soaps out of the household for many years. Eventually

Antibiotics Vs Tea Tree Oil To determine the effect of various different antibiotics and Tea Tree oil on the Bacillus subtillis different types of bacteria. I will test six antibiotics and the Tea Tree oil on Bacillus subtilis. I will test tetracycline‚ chloramphenicol‚ ampicillin‚ sulphatriad‚ penicillin G and Streptomycin. I would also like to see if Bacillus subtillis shows resistance to Antibiotics or to Tea Tree oil. The use of penicillin is being reduced because of the resistance

on the body of marine animals or internal organs of both aquatic and terrestrial animals. Amoeba reproduces asexually by binary and multiple fissions. They eat algae‚ bacteria‚ other protozoan‚ and tiny particles of dead plant or animal matter. Bacillus: They are rod shaped‚ gram positive bacteria found in soil and water. The largest are 2m across and 7m long. Most are aerobic but some under certain conditions can be facultative anaerobes. Each bacterium creates only one spore‚ which is resistant

We have a patient that may be infected with an unknown bacterial infection; we’ve collected a sputum sample and will be testing for one of the following genera: Bacillus‚ Escherichia and Mycoplasma. In order to determine which one of the three may be the source of the infection we have to recognize the characteristics of each one and the staining protocol needed to identify them. All three of the above mentioned

diaphragm aperture; the difference in lighting between adjacent areas of the specimen C. Describe your observations from fresh yogurt slide you prepared in Part III. While viewing under 4x magnification‚ you can see the presence of cocci and bacillus bacteria strains. After increasing the magnification to 10x‚ you can view these shapes more clearly‚ but it is not until 40x magnification that you can see the cooci exist in pairs and strands‚ in other words‚ diplococci and streptococci are present

would work best in killing the harmful bacterial strain‚ Bacillus subtilis. KB testing or disc diffusion antibiotic sensitivity testing is measured through the diameter in millimeters to find how resistant the antibiotic to the bacteria. The hypothesis of Windex fell correctly with my results but Lysol was only 4mm more sustainable then Windex. Lysol with the biggest zone of inhibition of 28mm allowing this disinfectant to kill the most Bacillus subtilis bacteria. Still‚ Lysol was succeeded to work

previous study (Jariyal et al.‚ 2014)‚ comparative analysis identified bacterial species Brevibacterium frigoritolerans‚ Bacillus aerophilus and Pseudomonas fulva as most potent phorate degrader‚ caused complete metabolization of phorate in 13 day. In view of the above‚ the phorate degradation ability of these bacterial strain could be arranged as Pseudomonas fulva strain Imbl 5.1> Bacillus aerophilus strain Imbl 4.1> Brevibacterium frigoritolerans strain Imbl 2.1. In view of the above‚ further studies
