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 is a biofilm. EPS is made of a combination of proteins, nucleic acids, lipids and polysaccharides which are secreted by the microorganisms themselves as a protective instinct. EPS offers protection for the microbes under conditions that are hazardous to their survival such as dessication and ultraviolet rays. The slimy film also allows the microbes to stick to surfaces for their nutritive requirements and is, thus, favorable to them.
However, to humans, biofilms can be destructive and can lead to different 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. On humans, the usual effects of these microorganisms are not felt when their immune sytem is functioning normally. The effects can be disastrous when they are sick or have medical condition or when their immune system is compromised by certain factos such as age and pregnancy.
Usually, biofilms are found in aqueous environments. In a typical home, they can be in areas where moisture is present. This is because most microorganisms thrive in humid environments. It is, thus, important to make sure that these particular areas in our home are kept dry and clean to avoid these microbial conglomerations. It is true that these biofilms have positive contributions to make, but mostly, they are for laboratory or industrial purposes. Non-pathogenic biofilms for example may be used to eat harmful organic material in wastewater to make it fit for human consumption. These biofilms of course will also be filtered out to prevent them from contaminating the water prior to distribution to homes and establishments.
Chemical methods of getting rid of 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. Cold water, as a matter of fact may be more uncomfortable for these organisms. There are chemical agents produced commercially as well for household use and they can be found on the internet.
