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

INTRODUCTION Bioinformatics is a branch of biological science which deals with the study of methods for storing‚ retrieving and analyzing biological data‚ such as nucleic acid (DNA/RNA) and protein sequence‚ structure‚ function‚ pathways and genetic interactions. Simply we can say that bioinformatics is the combination of computer systems and biological systems (figure: 1). It generates new knowledge that is useful in such fields as drug design and development of new software tools to create

Chapter 21 Notes: Kingdom Fungi! Name_________________________ 21-1: The Kingdom Fungi A. What Are Fungi? Fungi include MANY DIFFERENT types of organisms From tiny yeast cells To the one of the largest organisms in the world! Fungi are: Multicellular (except for yeasts) Eukaryotic Heterotrophic Decomposers: decompose dead and decaying material -Recyclers! -Secrete enzymes OUTSIDE bodies - Absorb digested nutrients Hyphae: long‚ slender‚ root-like filament Septa: cross-walls

microbial behavior (genetic and phenotypic expression) and the environmental conditions18. 2.3. Fed-batch processes The fed-batch technique was originally devised by yeast producers in the early 1900s to regulate the growth in batch culture of Saccharomyces cerevisiae18. Yeast producers observed that in the presence of high concentrations of malt‚ a by-product - ethanol - was produced‚ while in low concentrations of malt‚ the yeast growth was restricted. The problem was then solved by a controlled

History of Bread Grown in Mesopotamia and Egypt‚ wheat was likely first merely chewed. Later it was discovered that it could be pulverized and made into a paste. Set over a fire‚ the paste hardened into a flat bread that kept for several days. It did not take much of a leap to discover leavened (raised) bread when yeast was accidentally introduced to the paste. Instead of waiting for fortuitous circumstances to leaven their bread‚ people found that they could save a piece of dough from a batch
