Growth Dynamics of E. coli in Varying Concentrations of Nutrient Broths‚ pH‚ and in the Presence of an Antibiotic Dvora Szego‚ Elysia Preston Darcy Kmiotek‚ Brian Libby Department of Biology Rensselaer Polytechnic Institute Troy‚ NY 12180 Abstract The purpose in this experiment of growth dynamics of E. coli in varying media was to determine which media produces the maximum number of cells per unit time. First a control was established for E. coli in a 1.0x nutrient broth. This was used to compare

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

The effect of nutrient concentration on duckweed growth Gina Neonakis Biology 203L:11 Biology 203:10 November 14‚ 2011 Abstract Lemna minor‚ or duckweed‚ is a small plant that floats on the surface of stagnant water that is usually rich in nutrients. Phosphorus is an important macronutrient in the growth of aquatic plants. We tested the effect of phosphorus on duckweed population growth using a control medium rich in nutrients and compared it to the population growth in a medium that lacked

digestive enzymes are then released in the small intestine to help digest food. The main functions of enzymes are: • to digest carbohydrate‚ protein and fat (the three parts of food that supply calories); • to help with weight gain; and • to promote nutrient absorption. Because there appears to be a connec- tion between better lung function and higher body weights‚ it is very important to take enzymes with all meals and snacks. More than 90% of people who have CF take pancreatic enzyme replacements

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‚ blue light therapy

Essential Nutrients An essential nutrient is a nutrient required for normal body functioning that either cannot be synthesized by the body at all‚ or cannot be synthesized in amounts adequate for good health (e.g. niacin‚ choline)‚ and thus must be obtained from a dietary source. Essential nutrients are also defined by the collective physiological evidence for their importance in the diet‚ as represented in e.g. US government approved tables for Dietary Reference Intake. These are the six essential
