Micobiology website of Nicholas Pleat The goal here is to take the organisms that grew and grid them, therefore they are labeled and then I would be able to see if they grew in either or both an anaerobic environment as compared to an aerobic environment. Anaerobic bacterium are very diverse in their structure, and can be in the shape of rods, cocci, vibrios, spirilla, cornyforms, and sarcinas are common; the cells may be motile. Anaerobic bacteria are present in soil and are a part of the normal flora of humans and all other animals. web.rollins.edu /~npleat/index1.html   (1448 words)

Cellular Respiration We were able to observe first aerobic and then anaerobic respiration of yeast, and we saw how an export but lack of import of gases in anaerobic environments can add gas to an enclosed environment. To observe aerobic and anaerobic respiration of yeast in an enclosed, fluid environment, and in that way learn about cellular respiration as a whole. Yeast is a facultative anaerobe, meaning that it can participate in aerobic respiration when possible, but when this is impossible, it respires anaerobically. www.sidwell.edu /us/science/vlb5/Labs/Cellular_Respiration/cellular_respiration.html   (1572 words)

Metabolic Typing -- Oxygen and Anti-Oxidants While it is true that certain infections, cancers and other adversities thrive in an anaerobic environment, it is not true that anaerobic is “bad” and that aerobic is “good” or that everyone should do whatever possible to increase oxygen and aerobic metabolism in the body. A prolonged anaerobic metabolism is undesirable since many pathogens including bacteria, viruses, cancer, yeast, fungus and molds can thrive in that biochemical environment. For example, oxygen therapies are extremely beneficial, but only for someone who has an Anabolic, anaerobic imbalance. www.healthexcel.com /docs/_oxygen1.html   (1572 words)

Anaerobic Digestion Anaerobic digesters provide an environment for the oxygen-free decomposition of organic materials by bacteria.   In contrast, anaerobic digestion requires a sealed and often heated environment that has no oxygen present—similar to conditions in your own stomach. In each situation described above, different kinds of decomposing bacteria present work to break down complex fats, proteins and carbohydrates into simpler constituent elements.  When this happens in an anaerobic digester, one byproduct is methane, which can be used for energy.   www.michigan.gov /cis/0,1607,7-154-10401-83804--,00.html   (160 words)

Anaerobic Digestion Anaerobic processes can occur naturally or in a controlled environment such as a biogas plant. Anaerobic digestion is the bacterial breakdown of organic materials in the absence of oxygen. In controlled environments, organic materials such as sewage sludge and other relatively wet organic materials, along with various types of bacteria, are put in an airtight container called a digester where the process occurs. www.ciwmb.ca.gov /Organics/Conversion/Anaerobic   (134 words)

Feature Anaerobic digestion refers to the various reactions and interactions that, takes place converting complex organic materials to produce biogas, nutrient rich solids and liquid in an oxygen free environment. The anaerobic digestion process is one of the established technologies for sustainable processing of residues and wastes in the agro-food industry. Anaerobic micro-organisms digest the organic matter in the absence of oxygen, to produce Methane, Carbon dioxide and solid residue. www.dailynews.lk /2005/09/29/fea02.htm   (1221 words)

G1881 Generating Methane Gas From Manure, MU Extension The gas obtained in anaerobic digestion of animal wastes is a mixture of carbon dioxide and methane with trace amounts of hydrogen sulfide and hydrogen gas. The design volume of an anaerobic digester is sized according to the amount of volatile solids that must be treated daily and the period of time the material remains in the digester (detention time). A digester must be loaded with manure on a regular basis to ensure a continuous supply of food for the anaerobic bacteria. www.muextension.missouri.edu /xplor/agguides/agengin/g01881.htm   (3180 words)

Anaerobic Digestion Anaerobic processes could either occur naturally or in a controlled environment such as a biogas plant. Anaerobic digestion is a biological process that produces a gas principally composed of methane (CH4) and carbon dioxide (CO2) otherwise known as biogas. Many anaerobic digestion technologies are commercially available and have been demonstrated for use with agricultural wastes and for treating municipal and industrial wastewater. www.energy.ca.gov /development/biomass/anaerobic.html   (451 words)

Infection With Anaerobic Bacteria If infection with aerobic bacteria or facultative anaerobic bacteria occurs these bacteria may use up available oxygen thus making the environment more suitable for growth of anaerobic bacteria. These anaerobic bacteria are good things to have in a colon but bad things to have in a wound (infection),a brain or a lung (abscess). It is often the case that anaerobic bacteria and facultative anaerobes are both present in infected tissue. www.nuigalway.ie /bac/anaerobes.htm   (1241 words)

What are the byproducts of anaerobic respiration? Respiration (more commonly called breathing when applied to mammals) is what an organism is doing when it exchanges gas with the environment. When this happens, our muscle cells switch to anaerobic respiration -- instead of reacting with oxygen, the glucose breaks in half and forms lactic acid. The yeast and bacteria found in oxygen-deprived environments use compounds such as sulfate, carbonate, or nitrate in place of oxygen. www.yesmag.bc.ca /Questions/respiration.html   (437 words)

33930.980806&ELEMENT_SET=DECL Although the succinate ion is a common intermediate in the metabolic pathway of several anaerobic microorganisms, a need exists in the art for a fermentation process to economically produce succinic acid as well as other carboxylic acids such as malic acid and fumaric acid, in large amounts or with high yields. Anaerobic fermentation is the most ancient pathway for obtaining energy from fuels such as glucose. One problem is that the organism is a strict anaerobe, its cultivation must be performed in an environment absolutely free of oxygen. www.wipo.int /cgi-pct/guest/getbykey5?KEY=98/33930.980806&ELEMENT_SET=DECL   (7075 words)

Ch05 The biology of anaerobic hypersaline environments has been relatively little studied, though it is curious to note that the first bacteria ever isolated from the hypersaline environment (though not halophilic ones), Clostridia, causing tetanus and gas gangrene, was isolated by Lortet from Dead Sea mat in the end of the 19th Century (Oren 1983). Studies of anaerobic digestion showed that, in most ecosystems (including anaerobic digesters, aquatic sediments, black mud, marshes, swamps and other non-gastrointestinal environments), 70% or more of the methane formed is derived from acetate, depending of the type of starting organic carbon. The literature on anaerobic digestion is replete with information on the microbiology and biochemistry, environmental factors, biodegradability, kinetics, and health aspects of the anaerobic digestion process. www.fao.org /docrep/t0541e/T0541E05.htm   (7075 words)

Anaerobic Digestion (AD) Technical Pages. Anaerobic treatment and disposal.

Anaerobic Bacteria Anaerobic infection causes the formation of purulent abscesses.  There is tissue breakdown, invasion by PMNs, and finally, the abscess is walled off.  However, in the damaged and poorly oxygenated abscess tissue, the phagocytes are not able to eliminate the anaerobes.  For this reason, abscesses usually have to be drained. Obligate anaerobes cannot survive in an oxygen environment because they lack sufficient levels of the enzymes that allow them to detoxify the super oxide ion (i.e., peroxidases, catalase, and most importantly, superoxide dismutase). However, even severely neutropenic patients rarely get anaerobic infections, indicating that it is the oxygenation of tissues that provides the major protection against anaerobes. www.ratsteachmicro.com /Anaerobic_Bacteria_Notes/HCOE_CAI_Review_Notes_Anaerobic_Bacteria.htm   (1057 words)

Botulism, Botlulinum Toxin - MedPix™ Medical Image Database and Teaching Files The anaerobic organism Clostridium botulinum produce a potent neuromuscular toxin. Spores of the causative microorganism are found everywhere, but the growing conditions are relatively rigid - a non-acidic environment with low or no available oxygen. A related organism, C. tetani, produces a toxin with the opposite effect "tetany" - hence the disease nickname "Tetanus" or "lockjaw". rad.usuhs.mil /medpix/medpix.html?mode=single&comebackto=mode=geo_browse&recnum=971   (303 words)

Tetanus, Lockjaw, Clostridium tetani - MedPix™ Medical Image Database and Teaching Files Clostridium tetani is an anaerobic organism that produces a potent neuromuscular toxin that cause persistent muscle contractions (spasms, including opithotonos) or "tetany" - hence the nicknames "tetanus" and "lockjaw". Although the organism is everywhere, the growing conditions are quite specific - a non-acidic environment with low or no available oxygen. The classic "rusty nail" is a source of the living organism, that then causes a potentially fatal infection. rad.usuhs.mil /medpix/medpix.html?mode=single&comebackto=mode=geo_browse&recnum=972   (273 words)

Chapter 1 In anaerobic decomposition the pathogenic organisms do eventually disappear in the organic mass, as a result of the unfavorable environment and biological antagonisms. Considerable cellulose and lignin decomposition by actinomycetes and fungi can occur near the end of the composting period when the temperatures have begun to drop and the environment in a larger part of the pile is satisfactory for their growth. Anaerobic decomposition takes place in nature, as in the decomposition of the organic muds at the bottom of marshes and in buried organic materials to which oxygen does not have access. aggie-horticulture.tamu.edu /extension/compost/chapter1.html   (5727 words)
