coli bacteria, which, when found in high concentrations during routine water monitoring, can initiate a boil order.īiofilms can also be problematic in any fluid distribution system. These biofilms may get quite large in size until they eventually fall off in chunks, an event termed sloughing. The dead carcasses then form a barrier to the chlorine, which shelters the bacteria living inside. In this case, there are a few “poor souls” on the outside of the biofilm that sacrifice themselves for the preservation of the community. Biofilm bacteria can live on the distribution piping and may not be effectively killed by the continuous chlorination. This is often the root cause of boil orders for public drinking water systems. The character of the slime matrix shields the bacteria from harsh or caustic environments.

Protection is provided by “safety in numbers” from predation and attack by amoebae and macrophage. Bacteria do not have to move as the “nutrient conveyor belt” goes by they can pick and choose from the available “smorgasbord”. An attached existence in a flowing environment allows energy conservation for nutrient acquisition. There are many advantages for bacteria to live in a biofilm. These microscopic communities have been found to exist in nearly all aqueous environments where bacteria thrive, from deep-sea hydrothermal vents, distilled water systems, heart valves, and human teeth. Biofilms can be widely characterized as a community of microorganisms encased in a slime matrix attached to a surface. As more research evolved in this area, biofilms were discovered in virtually every hydrated environment.īacteria prefer biofilm communities, which afford protection and resistance conditions that are not available to their free-floating counterparts. To the surprise of the researchers, bacterial communities were found to be existing and even thriving in these environments with very low nutrients. Biofilms were first documented in alpine streams. One fairly recent discovery is that bacteria have the ability to live in a communal nature attached to a surface, termed a biofilm. The propensity of bacteria to live in myriad environments is testimony to their opportunistic nature. Some estimate that bacteria have existed on this planet for billions of years. Bacteria are extremely prolific and adapt to virtually all environmental conditions on the planet. SIP is performed to remove or kill attached bacteria within the piping systems. SIP is a process commonly used to sanitize or sterilize process piping. This approach, albeit good in theory, is misleading and can have dangerous consequences. This may be the reason many validation protocols do not recommend biological indicators and only specify thermal monitoring. Of great concern is the loss of biological indicators within the expanse of process piping during validation. Validation engineers face many challenges when validating steam-in-place or sterilization-in-place (SIP) systems. Mesa BGI Ambient Particulate Air Samplers
