Thus it is little difficult to completely control them. For example, the oil industry uses bacteria to clean up pollution created by spills and underground leaks and to clean up waste products from oil production.

Bioremediation is to clean up contaminated soil or water through using microorganisms. Biofeterioration page was last modified on 9 Decemberat Biofilms are the communities of micro organisms and have a self developed polymeric matrix and adherent to an inert or living surface. Bioaugmentation is addition of a group of natural microbial strains or a genetically engineered variant to treat contaminated soil or water. Biofilms usually have high resistance against antibiotics and disinfectants.

They are now also selling the biodeteriorationn to the nearby businesses. It depends on the chemical structure of the material and also the chemical and physical properties of materials and the invading organism.


These are huge tanks which sludge is pumped into from the settling tanks. It is full of nutrients and can be made into a supplement for livestock.

Retrieved from ” http: There are many reasons for microorganism having biofilms some of the advantages and disadvantages are outlined at “Bakers’ yeast Blooms into Biofilms. The deterioration of rubber by various fungi and actinomycetes might cause serious electrical problems to buried cables. It is usually formed with the attachment of the free floating microorganisms oc a surface.


Biodeterioration of sandstone under the influence of different humidity levels in laboratory conditions. Biodeterioration of stored diesel oil: Community Community portal Web chat Mailing list.

This is because the xenobiotics have been developed recently, from a geological viewpoint, and the existing microorganisms haven’t encountered them and therefore are not biodeteriorqtion to biodegrade them.

Remocion de colorantes reactivos empleando el hongo Bjerkandera adusta. Websites with more examples of biodegradation of xenobiotics: Certain organisms produce pigment or growth of cellular fibers.

Paper pulp can be produced chemically or mechanically. Bioventing is a process which provides oxygen by stimulating naturally occurring soil microorganisms to degrade components in soil. This historic site has suffered corrosion, despite treatment with synthetic polymers. The Palmerston North City Council Sewage Treatment Plant uses their methane to operate the central heating system and for maintaining the temperature in the digesters.

They use the carbohydrates, proteins and fats which they convert to organics and alcohols mostly acetic biodeteriroation propionic acids. It is found in the cell wall and appears as a complex with cellulose and hemicellulose polysaccharides. Bacteria when organised in biofilms can produce effective substances which cannot be produced by an individual bacteria.

It distributes the incoming sludge and keeps the organisms active by keeping a continuous supply available to them.

Produce consoritia which allows the recycling of substance 5.

For future work on smoke treatment for enhancing wood resistance to biodeterioration attack, wood species producing smoke via pyrolysis could be desirable for investigation because the chemical compounds of the wood species would be different from each other. Genitic exchange become easier due to proximity to progeny and other bacteria [6].

Suitable environmental conditions like temperature, moisture and oxygen are necessary for wood decay. Pseudomonas aeruginosa produces exopolysaccharide which makes it slimy. This is some current research into useful biodegradation on contaminated water: This website is a study conducted from samples of the Milan Cathedral.


Metals used in marine environments or the walls of the fuel tanks of jet aircraft are susceptible to microbial corrosion. Biodegradation of rubber is a slow process, bacteria utilizing rubber as a sole carbon source is also slow. When fiber is continuously exposed to temperature and moisture it changes. Biodegradation is the process of breaking down an organic substance by enzymes produced by living organisms.

The corrosion of metal pipes due to some bacteria triggers serious problems, particularly in oil and gas delivery systems. Wood decay is mainly caused by fungus. Bacteria bioodeterioration fungus cause deterioration in paper resulting in poor quality of sheets.

Valdes, is and the different types of Bioremediation [29]. Inside the tank, mixing is constantly moving the sludge around. Microbes are even able to last long within a low-nutritive environment of a biofilm. It is used against specific contaminants.

Microbial mats can be considered as complex biofilms. Chemical paper pulp produces less nutrients for microorganisms than the mechanical one. Prevention of biofilm formation and further biodeterioration on material used in space should emphasize surface engineering of materials so that initial attachment and susceptibility to microorganism can be minimized.

Minimises and prevents scum biodeteriodation up. These websites out line the prevention methods [26] used for Stone and Wood.

Living things found in teeth, gums, cells of intestinal or vaginal tract, and non living things found in medical devices such catheters. It maintains the same temperature throughout the tank.

This website outlines why biofilms occur and why microorganisms live in them Biofilms.
