Factory farming is a system of rearing livestock using intensive methods, by which poultry, pigs, or cattle are confined indoors under strictly controlled conditions. Factory farms control the U.S. food production. According to Safe.org.nz “Factory farming began around the nineteen sixties and nineteen seventies with the popularity of fast food” (paragraph 2). It created the ability for companies to buy larger quantities of meat for a lesser amount of money. Factory farming also affects the…

The purpose of performing physiological tests is to figure out certain characteristics of microorganisms or to reach a conclusion on what an unknown microorganism is. It can be also used to determine what is needed for bacteria to be cultured in or on certain media. Culture media can either be liquid or solid, and they can be used to identify certain characteristics of different bacterial species. This is indicated by the growth or lack of growth in or on certain media. Solid media can also be…

part of the antigen that is recognised by the immune system, specifically by antibodies. Extended Learning: Antisera evaluation: bacterial agglutination. Introduction: The Direct Agglutination Test (DAT) For over 80 years, subtyping of Salmonella enterica by serotyping has been a standard practise, a process in which surface antigens are recognised through agglutination reaction (2). Global health issues among developing countries Prevalence in Developing Countries: Future Research: …

Experimental trials were performed by students over a timeframe of three weeks to determine the identity of three unknown bacteria contained in broth medium stored in labeled test tubes that were randomly assigned containing: one Gram positive bacterium, one Gram-negative paracolon, and one Gram-negative coliform (Carson, 2016). The unknown sample assigned in this experiment was #19. After initially streaking the solution on clean streak plates and TSA agar, the identity was determined from a…

Introduction Over the past few years, there is a worldwide increasing tendency for the consumption of functional foods, including probiotics, prebiotics or both. Influenza epidemics cause numerous deaths and millions of hospitalization each year. Because of the alarming emergence of resistance to anti-influenza drugs, there is a need to identify new naturally occurring antiviral molecules. Punicaceae has been used for centuries in many cultures for the prevention and treatment of a wide…

1. INTRODUCTION Electrochemical Impedance Spectroscopy is an effective method of analyzing the intricate electrical resistance of a process and it is sensitive to surface phenomena and changes in the bulk properties. Thus it plays a major role in electrochemical research. It has been diligently used for the interpretation of corrosion mechanisms and in the characterisation of charge transport over the membrane. In the area of biosensors, it is especially appropriate for the detection of…

Introduction: The purpose of the tests (culture media, motility, enzymes, etc.) we preform on the numerous bacteria in lab is to show any biological or chemical characteristics of the bacteria that may help it survive or adapt in the wild, how it may be useful or hazardous to humans, and use as general knowledge to differentiate bacteria from each other. In the Culture Media test we can use solid and liquid media to grow multiple bacteria in lab. It can help us determine what processes the…

Raw material Boneless, skinless chicken breasts were purchased freshly from the butcher shops. Samples were prepared in average weight of 80±7 g fillets. All fillets including control and treated were packed in polypropylene trays and kept under refrigerated condition (4 °C) for 16 days. Preparation of LPOS LPOS was made at weight ratios of 1.00; 0.35; 108.70; 1.09 and 2.17 for LPO, glucose oxidase, α-D glucose, KSCN, and KI, respectively (15.5 mg of LPO was added) (Cissé et al.…
