when they are coming together to form biofilms, a manoeuvre that greatly strengthens their defences against immune-system attacks.
and silver ionisation to eradicate biofilm and legionella from water systems. We started this project in 2009 together with our SME partners in The netherlands Greece
The BIFIPRO system releases copper and silver ions into the water to eliminate biofilm a breeding ground for harmful bacteria like legionella.
which is a determining factor in the removal of biofilm and legionella. Mr van der Linde explains that the copper
The Geobacter biofilm encased by a network of nanowires and slime gives the bacteria a shield
As the biofilm concentrates many nanowires around the Geobacter cells more uranium can be mineralized bound
which surrounds the biofilm cells and boosts the Geobacter s pili armor so the biofilm now can pull double duty by helping mineralize uranium.
The shield keeps the uranium from penetrating deep into the Geobacter biofilm. By keeping this process on the surface of the film the bacteria are exposed not to uranium
and as a community they are able to clean up more toxic waste. he results surpassed our most optimistic predictionsreguera says. ven thin biofilms immobilized uranium like sponges.
They reduced it to a mineral all while not suffering any damage to themselves for prolonged periods of time. ven
when exposed to extremely high and toxic concentrations of uranium levels that would destroy individual Geobacter cells the biofilms didn t just survive they thrived she adds.
Reguera s future research will focus on deciphering how the biofilm matrix that encases the cells shields them so effectively
They have coaxed bacterial cells to produce biofilms that incorporate nonliving materials, essentially creating"living materials"that can be integrated into everyday objects and devices, from solar panels to adjustable furniture,
for the research because it naturally produces biofilms that contain so-called"curli fibers, "which are amyloid proteins that attach to surfaces.
Researchers then programmed the E coli cells to produce biofilms with the conducting properties of gold nanowires.
thus having the ability to change the composition of their biofilms over time.""It a really simple system but what happens over time is you get curli that increasingly labeled by gold particles.
and biofilms with enzymes that catalyze the breakdown of cellulose could be used for the conversion of agricultural waste into biofuels.
and other substances including living cells MIT engineers have coaxed bacterial cells to produce biofilms that can incorporate nonliving materials such as gold nanoparticles and quantum dots.
because it naturally produces biofilms that contain so-called curli fibers amyloid proteins that help E coli attach to surfaces.
These peptides can capture nonliving materials such as gold nanoparticles incorporating them into the biofilms. By programming cells to produce different types of curli fibers under certain conditions the researchers were able to control the biofilms properties
and create gold nanowires conducting biofilms and films studded with quantum dots or tiny crystals that exhibit quantum mechanical properties.
They also engineered the cells so they could communicate with each other and change the composition of the biofilm over time.
First the MIT team disabled the bacterial cells natural ability to produce Csga then replaced it with an engineered genetic circuit that produces Csga
which forms curli fibers that coalesce into a biofilm coating the surface where the bacteria are growing.
The two types of engineered cells can be grown together in a colony allowing researchers to control the material composition of the biofilm by varying the amounts of AHL and atc in the environment.
Cells that talk to each other The researchers also demonstrated that the cells can coordinate with each other to control the composition of the biofilm.
The researchers are interested also in coating the biofilms with enzymes that catalyze the breakdown of cellulose
Lu engineered phages that could break apart antibiotic-resistant biofilms coatings where bacteria live and thrive by injecting bacteria with certain enzymes to make the biofilms self-destruct.
This discovery would earn Lu the $30, 000 Lemelson-MIT Student Prize, in 2008, and a spot on Technology Review 2010 list of top innovators under 35.
Seeing phages as better antimicrobial treatments than antibiotics to which biofilms and bacteria can build immunity Lu, Sample6 cofounder and now vice president of operations Michael Koeris,

to break apart the biofilms that build up and corrode oil pipelines, or to detect the pathogenic bacteria that sometimes cause oil to sour by changing its composition.
Stocker says in some cases that phenomenon could lead to new approaches to tuning flow rates to prevent fouling of surfaces by microbes potentially averting everything from bacteria getting a toehold on medical equipment to biofilms causing drag on ship hulls.
One prominent location is near the walls of tubes where the result is a strong enhancement of the bacteria s tendency to adhere to those walls and form biofilms.
But this effect varies greatly depending on the speed of the flow opening the possibility that the rate of biofilm formation can be tweaked by increasing or decreasing flow rates.
Biofilms are found everywhere Rusconi says adding that the majority of bacteria spend significant fractions of their lives adhering to surfaces.
Bacteria concentrated in biofilms are up to 1000 times more resistant to antibiotics than those suspended in liquid.
and idea owing to the major importance of bacterial biofilms The research was supported by the National Science Foundation and by a Gordon and Betty Moore Marine Microbial Initiative Investigator award to Stocker r

"Anodized metals could be used to prevent buildups of biofilms slick communities of bacteria that adhere to surfaces
As a result, the coating primarily counteracts the formation of an extensive biofilm. The researchers were able to prove the double microbicidal
and biofilm-inhibiting action using the standardised ASTM E2 180 test process. The new material can be applied to a variety of substrates such as plastic,
Researchers say that being able to control the production of the biofilm in agricultural products could enable improved protection for plants.

or biofilms, already growing on the bone fragments. They demonstrated this by first allowing bacteria to colonize the bone
It was also able to remove bacterial biofilms that typically cause dental disease and was effective at removing soft tissue from bones,
Starstream's effectiveness was demonstrated further with the publication of two additional papers--further results on its effectiveness against dental biofilms were published in the Journal of Dental Research,
Researchers at Unit 1121"Biomaterials and Bioengineering"(Inserm/Strasbourg university) have succeeded in creating a biofilm with antimicrobial, antifungal and anti-inflammatory properties.

"Research has shown that people with chronic sinusitis often have bacteria in their sinuses that have created biofilms--communities of bacteria with sticky protective covers that help them evade antibiotics and flourish unchecked.
These properties also give biofilms a unique biochemical fingerprint. Thinking that biofilms could be part of the solution, in 2008,
Das received a KL2 trainee award from Ohio State's Center for Clinical and Translational Science (CCTS) to start working with one of the nation's leading bacteriologists, Lauren Bakaletz, Phd.
had made already several critical discoveries about a type of biofilm-building bacterium called nontypeable Haemophilus influenzae (NTHI),
Bakaletz and Das started searching for the unique biochemical signature of NTHI's biofilm. In the process, they developed a novel chinchilla model of bacterial sinusitis following a viral infection.
After looking at hundreds of proteins secreted by NTHI biofilms, they landed on two candidates:
outer membrane protein (OMP) 2 and 5--proteins that were predominantly present within biofilms formed by NTHI.
With the biofilm signature in hand, the two scientists then invented a technology that reacts to the presence of NTHI proteins by changing color, much like a rapid strep or pregnancy test.
These large complex molecules form slimy biofilms and bind waterborne organic matter into larger particles in which disease-causing microorganisms can become embedded
Secondly the polymers help to form sticky biofilms which can trap the T. gondii egg cells and coat kelp on which marine snails graze.
The study is the first to demonstrate how leptospira mutates to form a biofilm, an extra protective layer of microbial cells,
This biofilm, created with help from the plant bacteria, made leptospira almost invincible when attacked with normal doses of antibiotics, ultraviolet radiation or even heat.
"The biofilms showed very high resistance to Penicillin g, ampicillin and tetracycline, some of the leading antibiotics used to treat acute leptospirosis in humans
"The biofilms also increased leprospira's tolerance to UV radiation and high temperature. It could withstand up to 49 degrees C,
"This biofilm protects the leptospira from adverse environmental conditions, and is probably the key factor for its persistence and survival,
