Option F: Microbes and Biotechnology Diversity of Microbe F.1.1 Outline the classification of living organisms into three domains. Three domains of living organisms: 1. Archaea - very primitive; live in extreme habitats 2. Eubacteria - more advanced 3. Eukaryota - all life forms with eukaryotic cells (have a nucleus) Use of ribosomal RNA sequences for classification rRNA is found in all cells rRNA is easy to isolate Analyzed to determine the exact sequence of nucleotide bases

Jane Ventura Dr. John Schillinger HSCI 132 November 10‚ 2012 Climate Change and Food Borne Illness Climate has always played a significant role in placing food on the tables of millions of families. It seems that we have regressed judging from the way that our ancestors have lived their lives to the way that we have become dependent on mass production of food. We have managed to sabotage our health as well as that of the Earth’s. The changes in weather patterns have gradually impacted agriculture

Rennet (pron.: /ˈrɛnɨt/) is a complex of enzymes produced in any mammalian stomach‚ and is often used in the production of cheese. Rennet contains many enzymes‚ including a proteolytic enzyme (protease) that coagulates the milk‚ causing it to separate into solids (curds) and liquid (whey). They are also very important in the stomach of young mammals as they digest their mothers ’ milk. The active enzyme in rennet is called chymosin or rennin (EC 3.4.23.4) but there are also other important enzymes

INTRODUCTION Pneumonia is an inflammation of the lungs caused by an infection. It is also called Pneumonitis or Bronchopneumonia. Pneumonia can be a serious threat to our health. Although pneumonia is a special concern for older adults and those with chronic illnesses‚ it can also strike young‚ healthy people as well. It is a common illness that affects thousands of people each year in the Philippines‚ thus‚ it remains an important cause of morbidity and mortality in the country. There are many

I. INTRODUCTION Pneumonia is an inflammation of the lung parenchyma caused by various microorganisms‚ including bacteria‚ mycobacteria‚ fungi‚ and viruses. Pneumonias are classified as community- acquired pneumonia (CAP)‚ hospital-acquired (nosocomial) pneumonia (HAP)‚ pneumonia in the immunocompromised host‚ and aspiration pneumonia. There is overlap in how specific pneumonias are classified‚ because they may occur in differing settings. Those at risk for pneumonia often have chronic underlying

were studied. The findings of the chemical study of essential oil of L. camara leaves revealed the presence of a high amount of sesquiterpenes and this oil remarkably inhibited the growth of most tested bacteria and fungi; Pseudomonas aeruginosa‚ Aspergillus niger‚ Fusarium solani and Candida albicans appearing as the most sensitive (Sousa et al.‚ 2012). Considerable research‚ such as this one‚ has focused primarily on the antibacterial properties the essential oil of the Lantana camara has. This research

Use of Enzymes in Food Industry - Food industry utilizes a variety of enzymes for processing of various foods‚ e.g.‚ production of various types of syrups from starch or sucrose (a- and β- amylases‚ glucamylase‚ pullulanase‚ invertase‚ and glucose isomerase)‚ meat/protein processing using proteases‚ removal of glucose and or molecular oxygen (O2) using glucose oxidase and catalase‚ use of lactase in dairy industry and use of enzymes in fruit juice and brewing industries. Glucose oxides are obtained
