The use of Bacillus spores as probiotics and bio-control agent increased significantly, compared to previous years. A new approach in the abatement of certain pathogenic microorganisms is the use of antagonistic microorganisms. This approach is based on the application of probiotic bacteria in human and animal intestines to create a pathogen unfriendly environment, stimulating the host’s overall health. Expansion of the probiotic concept towards the environment has designated a biocontrol, when the application is antagonistic towards a certain pathogen [10]. Recently, the ‘health’ of hospital surfaces has been re-thought as the health of the human body, considering that, rather than eradicating all pathogens, replacing them by beneficial microbes might be more effective in preventing infections [11, 12].
In 2018 The Biology and Built Environment Center (BioBE) conducted controlled trials of the BetterAir
Biodify™ device. The conclusion of the study’s final report that was issued on February 20th, 2019, is summarized by the following words: “There were significantly lower numbers of Cladosporium sp. in treated versus control samples, as well as a decrease over time in Cladosporium numbers during treatment with Enviro-Biotics. This evidence suggests that Enviro-Biotics treatment could play a role in decreasing Cladosporium sp., and potentially other molds and mildews within the environment.”
This study was conducted in a controlled environmental chamber by the BIOBE staff led by Dr Jessica Green. Furthermore, we are still in process of gathering data from recent trials.
