Study of Bacterial Growth and Resistance Level to Certain Antibiotics INTRODUCTION Escherichia coli—better known as E. coli—is a gram negative‚ rod shaped bacteria. It is relatively harmless‚ but can occasionally cause food poisoning. It can also provide Vitamin K2. It prevents the establishment of pathogenic bacteria‚ and is associated with or found in the intestinal organ. The antibiotic that E. coli is resistant to is Penicillin. Bacillus subtilis—better known as B. subtilis—is known as

Paper cone Lab Variables: - Independent: The independent variable is the diameter of the paper cone’s base. - Dependant: The time will be measured to see how long does it take the paper cone to land on the floor. For this measurement we are going to use a stopwatch and the time measured is going to depend on our reaction time. - Controlled: The mass of the paper cone and also the height from which we are going to drop the paper cone are constant. The acceleration due to gravity will

Performance Liquid Chromatography (HPLC) Instructor: Dr. Hüseyin BOZKURT High Performance Liquid Chromatography (HPLC) is one mode of chromatography‚ the most widely used analytical technique. Chromatographic processes can be defined as separation techniques involving mass-transfer between stationary and mobile phases. Present day liquid chromatography that generally utilizes very small packing particles and a relatively high pressure is referred to as high performance liquid chromatography (HPLC).

about how many calories are in their food‚ if there’s glucose in it‚ or something else along those lines‚ but what consumers generally think about when they eat is how much radiation has been pumped into their food prior. Yes that’s right‚ many foods that you eat are treated with different forms of radiation. Food irradiation is the process of treating food with ionizing radiation in order make it healthier to eat. There are many benefits to the irradiation of food and this fact should be recognized
