bio gas Co-digestion of Biomass for Methane Production: Recent Research Achievements Wei Wu ABSTRACT Anaerobic digestion (AD) is a process by which microorganisms break down biodegradable material in the absence of oxygen. Anaerobic digestion can be used to treat various organic wastes and recover bio-energy in the form of biogas‚ which consists mainly of CH4 and CO2. A great option for improving yields of anaerobic digestion of solid wastes is the co-digestion of multiple substrates. Numerous

Bacterial Biology █ BRIAN D. HOYLE An understanding of the fundamentals of bacterial biology is critical to bacteriologists and other forensic investigators attempting to identify potential biogenic pathogens that may be exploited as agents in biological warfare or by bioterrorists. Fundamentals of Bacterial Biology Bacteria are one-celled prokaryotic organisms that lack a true nucleus (i.e.‚ a nucleus defined by a membrane). Bacteria maintain their genetic material‚ deoxyribonucleic

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

BIO 113 Spring 2012 - Dr. MJ Bernot Study Guide – Exam 2 Chapter 7- IS AT THE BOTTOM. Bernot wrote it so hopefully it is useful • Describe the structure of DNA and discuss how it facilitates the ability of DNA to act as genetic material • Compare and contrast prokaryotic and eukaryotic chromosomes • Describe the process of DNA replication as a semi-conservative process. Compare and contrast the synthesis of the leading and lagging strands in DNA replication. • Explain

Water is one of the many things that all human being need in order to survive. Considering the vast amount of water that is on the planet‚ it is reasonable to believe that there is more than enough water for everyone to have their fair share and more. Yet this sadly is not the case‚ as the majority of the water on Earth is unsuitable to drink due to the fact that it is tainted with a numerous amount of contaminants‚ such as bacteria and salt. The amount of safe drinking water is decreasing more

Lyme disease is a bacterial disease that affects over 200‚000 each year. It is caused by the bacteria Borrelia burgdorferi. It is transmitted through the bite of blacklegged ticks (deer ticks). These ticks are found in grassy and wooded areas. Female nymphal or young black-legged ticks carry and transmit the Lyme disease bacteria Borrelia burgdorferi the most. Common symptoms of Lyme disease are fever‚ muscle pain‚ joint pain‚ headache‚ fatigue‚ and a characteristic skin rash called Erythema migrans

Abstract The Greek-Roman Isis temple is located on the west bank of Luxor; Upper Egypt was made of sandstone and decorated with different kinds of wall paintings. It suffers from many causes of deterioration and degradation mainly ground water‚ salt weathering‚ and different types of dirt accumulations on the relives and paint surface such as soot‚ grease‚ wax‚ biodeteriorated colored patches‚ bat patches‚ waste of birds and even house fly specks. All these lead to the gradual disappearance of paintings
