Bacteria anaerobes

The manner in which many of these bacteria cany on their chemical processes is qmte comphcated and in some cases not fuUy understood. The role of sulfate-reducing bacteria (anaerobic) in promoting corrosion has been extensively investigated. The sulfates in shghtly acid to alkaline (pH 6 to 9) soils are reduced by these bacteria to form calcium sulfide and hydrogen sulfide. When these compounds come in contact with underground iron pipes, conversion of the iron to iron sulfide occurs. As these bacieria thrive under these conditions, they will continue to promote this reaction until failure of the pipe occurs. 

Anaerobic Bacteria (anaerobes) group of bacteria that are unable to multiply in anv but a minute trace of oxygen.

It is difluorinated quinolone effective against gram positive bacteria, anaerobes and mycobacteria. It is used in the treatment of pneumonia, chronic bronchitis, sinusitis etc. 

An action level in microbiological environmental monitoring is that level of microorganisms that, when exceeded, requires immediate follow-up and, if necessary, corrective action. The evaluation does not depend only on the number of colonies but also on the types of microbes isolated and the suspected hazard from them, e.g.. Gram-negative bacteria, anaerobic bacteria, fungi, or organisms not normally isolated. 

To demonstrate that the mixture does not manifest antimicrobial activity, carry out the test as described previously up to the incubation step and add an inoculum of viable cells of the specified aerobic bacteria, anaerobic bacteria, and fungi. 

The sulfur-oxidizing bacteria. Anaerobic conditions prevail in marine sediments, in poorly stirred swamps, and around hydrothermal vents at the bottom of the sea. Sulfate-reducing bacteria form high concentrations (up to mM) of H2S (in equilibrium with HS and s2-)318-320 This provides the substrate for bacteria of the genus Thiobacillus, which are able to oxidize sulfide, elemental sulfur, thiosulfate, and sulfite to sulfate and live where the aerobic and anaerobic regions meet.311 321-323 Most of these small gram-negative...

The lower female genital tract generally is colonized by a large munber of aerobic and anaerobic bacteria. Anaerobes may number 10 organisms per milliliter and often include lactobaciUi, eubacte-ria, Clostridia, anaerobic streptococci, and less frequently, Bacteroides frag il is. Aerobic bacteria most often are streptococci and Staphylococcus epidermidis, and these may munber 10 organisms per milbliter.
