The microbial community, microflora and biofilm are a living entity, with continuous changes depending on the conditions (humidity, power, temperature …). Despite these changes, it is the aim of the microbial community to continue existing, and remain alive as long as possible The microorganisms can do that by adapting to the circumstances and by communicating (called quorum sensing) with each other.
Suppose one has a surface that provides adequate nutrition, moisture and space with a microbial community of up to 100 micro-organisms. The present micro-organisms interact with each other to ensure that they do not exceed that limit, preferably remaining a little below the limit to ensure they do not have a sudden problem..
An example of such a surface is set out below:
(Total 100: 42 good, 18 bad, 40 empty))
The surface is covered with harmless microorganisms (green spheres), harmful micro-organisms (red spheres) and some spaces that serve as a backup. Since the micro-organisms have an average life span of a few days, there will be a process of continuous dying and growing from micro-organisms, and the total microbial community remains approximately constant. Without human influence, there is a microbial ecosystem or natural microflora balance.
In Chemical cleaning and disinfection we show you the impact of chemical cleaning and disinfection on this microbial balance.
