Biofilm is a term that refers to any group of microorganisms such as bacteria, fungi and protozoa or products of corrosion that are contained in a slimy biological product known as extracellular polymeric substance. It is a combination of nucleic acids, proteins, lipids and polysaccharides, EPS, which are secreted by the microorganisms themselves as a protective instinct. EPS provides protection for the microbes under conditions that are detrimental to their survival such as dessication and ultraviolet rays. Also, the slimy film allows the microbes to stick to surfaces for their nutritive requirements and is, thus, favorable to them.
However, to human beings, biofilms can be destructive and can lead to several diseases. The most toxic of these risks can be found in medical equipment which has been exposed to pathogens. But people may encounter biofilms in their own homes, offices and in public places without their knowing each single day. The usual effects of these microorganisms on human beings are not felt when their immune sytem is functioning normally. But when their immune system is compromised by certain factors such as age and pregnancy, the effects can be disastrous.
Usually, biofilms are found in aqueous environments. In a typical home, they can be in bathrooms, sinks, swimming pools and other areas where moisture is present. This is due to the fact that most microorganisms thrive in humid environments. Thus, it is vital to make it a point that these particular areas in our home are kept dry and clean to steer clear from these microbial conglomerations. It is true that these biofilms have positive contributions to make, but mostly, they are for laboratory or industrial purposes. For example, to make it fit for human consumption, non pathogenic bioflims may be used to eat harmful organic material in wastewater. Of course, to prevent them from contaminating the water prior to distribution to homes and establishments, these biofilms will also be filtered out.
Chemical methods of eliminating these films may be done in in laboratory settings through the use of enzymes and other chemical substances. But in ordinary households, it can be made possible with manual, ordinary approaches such as brushing or using special vacuums. There is a impression that warm water kills these microorganisms, but it doesn't do the trick. In fact, for these organisms, cold water may be more uncomfortable. Also, there are chemical agents produced commercially for household use and they can be found online.
