Catabolism Of Amino Acids To Volatile Fatty Acids By Lactococcus Lactis, Balasubramanian Ganesan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Lactic acid bacteria are essential as flavor producers of cheese and fermented products. They are capable of catabolizing aromatic, branched chain, and sulfur amino acids to flavor compounds. During cheese ripening the numbers of lactococcal colonies decrease, but lactococci survive without replication in culture. This prompted an investigation into possible mechanisms of catabolism of branched chain amino acids into branched chain fatty acids and the physiological relevance of amino acid catabolism to the bacteria. We hypothesized that lactococci catabolize branched chain amino acids to branched chain fatty acids during nonculturability.

Lactococci, lactobacilli, and brevibacteria catabolized both branched chain amino acids …

"Bariatic Surgery For Obese Adolescents", Hilary Brooke Spooner

Undergraduate Honors Capstone Projects

With the rise of adolescent obesity, the need for treatment of this life-threatening disease is under consideration. There are several methods for the treatment of this disease, but a newer method is on the rise. Bariatric surgery for adolescents is a new technique that has been performed on adults for years, but the effects on the younger population are still unknown. There are certain criteria and guidelines for the patients undergoing this surgery, but the results seem to be promising. Nutritional and surgical complications are of great concern, but are the chronic disease health benefits brought on by weight loss …

The Composition And Comparison Of Essential Oils And Their Nutritional Benefits To Enhance And Decrease Risk For Chronic Disease, Heather Wollschleger

Undergraduate Honors Capstone Projects

This paper reviews the current status of our knowledge of essential oils and their nutritional contribution to our diet. The effects of dietary fats on our health differ markedly from the type and form of the fat. Special emphasis is placed on omega-3 and omega-6 fatty acids, and their dietary involvement. Specific oils increase our levels of vital vitamin E and the essential omega-3 and omega-6 fats humans need for mental and physical health. Chronic diseases remain a major cause of death and disability, and risk factors include diets high in saturated fatty acids and trans fatty acids. This risk …

The Macrobiotic Diet May Have Benefits In Cancer Prevention, Brittany Lewis

Undergraduate Honors Capstone Projects

Macrobiotics is one of the most popular alternative or complementary approaches to fighting cancer. The diet is primarily plant-based, is centered on the idea of an all encompassing "yin-yang" concept in life, mind, environment and food. The dietary components of the macrobiotic diet, along with the many lifestyle implications are shown to have beneficial effects in cancer prevention and therapy. The diet has many anti-carcinogenic compounds, as well as a decrease in foods thought to promote cancer. A cause for concern is the vitamin deficiencies that may ensue in following a strict macrobiotic diet, which typically results from an all …

The Adverse Health Effects Of Trans Fatty Acids, And Implications For Public Policy, Jonathan D. Atkin

Undergraduate Honors Capstone Projects

Subject: Trans fatty acids (TFAs) are produced either by the process of bacterial hydrogenation in the stomachs of ruminant animals, or the commercial method called industrial hydrogenation. The latter began early in the 20^th century based on purported health benefits and lowered costs. Alarming results from scientific studies in the early 1990's began to raise questions about whether TFAs should be regulated in our food supply.

Findings/Statistics: Scientific research initially discovered that TFAs raise the LDL/HDL ratio, thereby increasing the risk of coronary heart disease (CHD). Recent large, prospective, population-based studies have indicated a 25% increased risk of ischemic …

Replacement Of Fish Meal By Meal Worm (Eisenia Foetida) In The Feed Of Broilers As An Alternative Source Of Protein, Carlos ÁNgel Cervantes Cevallos

Theses and Dissertations

This investigation was conducted in the rural community of Cuambo, located in the northeast of Imbabura province, in the Mira river basin of Salina parish, at 1530 meters above sea level and with an average temperature of 19 C. The principal objective of this investigation was to evaluate the effect of four levels of substitution of fish meal for earthworm meal in broiler chicken diets. The fieldwork occurred in two stages over the course of 20 months: A. Creation of the feed: This step lasted from the installation of an earthworm culturing area through the cultivation, harvest, and drying of …

Biochemical And Molecular Nutrition Blocks As Dietary Supplements In Llamas (Lama Glama) In The Last Third Of The Gestation Period Of The Ceac, Janette Illanes Callejas

Theses and Dissertations

The present work consisted in the use of biochemical and molecular nutrition blocks (BMN) in llamas during the last third of the gestation period, at the Agricultural Experiment Center of Condori (CEAC), located 49 km north of the city of Oruro, and 12 km north of the Caracollo population, in the province of Cercado. For this research work, we used 20 pregnant llamas in the last third of their gestation period, between the ages of 2 and 3 years old, 10 of which belonged to the Khara breed, and 10 to the Thampulli breed. Two corrals of 7 x 7 …
