Antibiotic Drug Resistance
This book presents a thorough and authoritative overview of the multifaceted field of antibiotic science – offering guidance to translate research into tools for prevention, diagnosis, and treatment of infectious diseases.
Antibacterial effects of Algae
An alarm increase in the rate of emerging of resistance bacteria have been causing a great public concern worldwide. This problem of increasing resistance has necessitated the search for safe and effective factors that may be used to treat persistent bacterial infections or modify the currently available antibiotic. This study deals with the antimicrobial potential assessment of ulva flexuosa , ulva flexuosa was collected from at MAZAR ELKHODER. Crude organic extracts were prepared using methanolic and chloroformic extract and tested against 6 indicator microorganisms using the disk diffusion method and also applied against biofilm ( dental plaque).
Amino acid biosynthesis : Pathways, regulation and metabolic engineering
Amino Acids Biosynthesis presents the current knowledge of fundamental as well as applied microbiology of amino acids. Topics discussed are the amino acid biosynthetic pathways, their genetic and biochemical regulation, transport of amino acids and genomics of producing microorganisms. The characterization of the control mechanisms of amino acid biosynthesis has revealed insights into principles of genetic and biochemical regulation, such as transcriptional regulators and a new class of regulatory elements, the riboswitch. The volume further deals with the metabolic engineering of microorganisms for the biotechnological production of amino acids for use as pharmaceuticals and, particularly, as food and feed additives.
Alkaliphiles : Genetic properties and applications of enzymes
The pioneering work of Dr. Koki Horikoshi on the discovery, research and applications of alkaliphilic bacteria are described here in their entirety. The isolation, distribution and taxonomy of alkaliphilic microorganisms as well as their cell structure and physiology are discussed for a basic understanding of these entities. The molecular biology and genome sequencing of some alkaliphilic bacterial strains are also presented. Part II of the volume focuses on enzymes of alkaliphiles and their applications. These include alkaline proteases, starch-degrading enzymes and numerous others. Some of these enzymes are currently in wide commercial use as laundry detergent additives and in wastewater treatment. Alkaliphiles are a relatively recent field of research that will no doubt provide avenues to a wide range of further discoveries and applications for a new generation of workers in bioscience and technology.
Adaptation to Life at High Salt Concentrations in Archaea, Bacteria, and Eukarya
This book complements “Halophilic Microorganisms”, edited by A. Ventosa and published by Springer-Verlag (2004), “Halophilic Microorganism and their Environments” by A. Oren (2002), published by Kluwer Academic Publishers as volume 5 of “Cellular Origins, Life in Extreme Habitats and Astrobiology” (COLE), and “Microbiology and Biogeochemistry of Hypersaline Environments” edited by A. Oren, and published by CRC Press, Boca Raton (1999).
A Closer Look at Antibiotic Resistance
Bacterial infections have become more difficult, and sometimes impossible, to treat due to antibiotic resistance, which occurs when bacteria develop the ability to defeat the available drugs designed to kill them. According to the Centers for Disease Control and Prevention, each year, 2 million Americans become sick with antibiotic-resistant infections, and of that, about 23,000 die. This book examines the challenges related to antibiotic resistance, the development and use of diagnostic testing to identify antibiotic resistance, the development of treatments for resistant infections, and appropriate antibiotic use.
