CHAPTER I INTRODUCTION 1.1 Background Food is one of human sources of calorie‚ protein‚ fats‚ and nutrition. Yet‚ because of the highly nutritious content‚ food is susceptible to growth of microorganisms. By the presence of microorganisms in food‚ the food is more likely to have shorter shelf life. Thus‚ mostly it is resolved by the addition of antimicrobial substances to food‚ such as condiments and preservatives. Condiments and preservatives could inhibit the growth of microorganisms

Escherichia coli Microbiology Lab NAS 185-14L Introduction In this lab experiment we did several test to determine what our unknown bacteria was. To determine this we recorded the results of how the bacteria reacted to different media. Depending on the results of each test we could narrow down the different bacteria to determine what our unknown is. This experiment will also determine if our bacteria is a fermenter of sugars and if it is catalase positive. If the bacteria is

Open Reading Frames * (ORFs) are regions with no stop codons. All genes reside in long open reading frames * Note that stop codons in other reading frames have no effect on the gene. * Can be searched in the genome sequence. Valid only for prokaryotes and lower eukaryotes. Protein Sequencing vs. DNA sequencing * We compare protein sequences‚ not DNA‚ because protein is more conserved in evolution than DNA * The organism’s survival depends on the protein being

Gram-negative bacteria based on their cell wall. Most of the bacteria or yeast in the starter cultures used are Gram-positive. Gram staining requires 4 types of solutions used in the procedure: crystal violet‚ mordant‚ alcohol and safranin. The Gram-positive microbes will have blue stain while Gram-negative stains pink after the procedure. Methylene blue solution is a

What is Food Microbiology Food microbiology is the study of food micro-organisms; how we can identify and culture them‚ how they live‚ how some infect and cause disease and how we can make use of their activities. Microbes are single-cell organisms so tiny that millions can fit into the eye of a needle. They are the oldest form of life on earth. Microbe fossils date back more than 3.5 billion years to a time when the Earth was covered with oceans that regularly reached the boiling point‚ hundreds

Quantification of Microbes in Milk and Water Naomi Hall 10/20/14 BSC 381L H003 Group: Megan Baker‚ Katie Coe and Meagan Williams Abstract Coliforms are gram negative bacteria commonly found in the intestines of birds and mammals and are the most widely utilized indicators of fecal contamination. The purpose of this experiment was to test various water and milk samples for the presence of coliforms‚ specifically fecal coliforms. It was expected that fecal coliforms would be found in all
