What Are Probiotics?<\/h2>\n\n\n\n
Probiotics are live microorganisms that, when applied in adequate amounts, can help maintain or restore the balance of microbial ecosystems. While best known in the context of digestive and animal health, probiotics are increasingly used in cleaning technologies to support healthier indoor environments. In MBCPs, probiotics are introduced to surfaces where they support microbial stability and contribute to ongoing surface cleanliness through enzyme production.<\/p>\n\n\n\n
Among probiotic microorganisms, Bacillus<\/em> species are especially valued in external cleaning products due to their resilience and enzymatic activity.<\/p>\n\n\n\n <\/p>\n\n\n\n Written by Sofija Andric<\/a>, Scientific Manager at Probiotic Group Luxembourg S.A.<\/a><\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" R&D laboratory level 2 situated in Esch-Belval, Grand-Duchy of Luxembourg.<\/p>\n","protected":false},"author":3,"featured_media":38175,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[369],"tags":[647,645,646,644,643],"class_list":["post-38171","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-our-articles","tag-mbcp","tag-microbiology","tag-probiotics","tag-rd","tag-science"],"_links":{"self":[{"href":"https:\/\/www.provilan.com\/en\/wp-json\/wp\/v2\/posts\/38171","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.provilan.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.provilan.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.provilan.com\/en\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.provilan.com\/en\/wp-json\/wp\/v2\/comments?post=38171"}],"version-history":[{"count":1,"href":"https:\/\/www.provilan.com\/en\/wp-json\/wp\/v2\/posts\/38171\/revisions"}],"predecessor-version":[{"id":38208,"href":"https:\/\/www.provilan.com\/en\/wp-json\/wp\/v2\/posts\/38171\/revisions\/38208"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.provilan.com\/en\/wp-json\/wp\/v2\/media\/38175"}],"wp:attachment":[{"href":"https:\/\/www.provilan.com\/en\/wp-json\/wp\/v2\/media?parent=38171"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.provilan.com\/en\/wp-json\/wp\/v2\/categories?post=38171"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.provilan.com\/en\/wp-json\/wp\/v2\/tags?post=38171"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Why Bacillus?<\/h2>\n\n\n\n

Modes of Action of Probiotics in MBCPs:<\/h2>\n\n\n\n
\n
Bacillus<\/em> spores introduced through MBCPs adhere to treated surfaces, integrate into the surface microbiota, and germinate into active cells in response to environmental moisture and\/or the presence of nutrients (dirt). Once metabolically active, they interact with the surroundings and persist over time. If the unfavourable environmental conditions appear (no humidity, no nutrients), Bacillus<\/em> can survive them by its natural spore-forming capacity. These spores will persist until the new optimal conditions develop.
<\/li>\n\n\n\n
After attachment and successful colonisation, activated Bacillus<\/em> cells secrete extracellular enzymes, such as proteases, lipases, amylases, etc. These enzymes break down complex organic materials, such as food particles, grease, and other residues, into smaller molecules, which are further used as a nutrient source by Bacillus<\/em>. This contributes to surface cleanliness by enabling the removal of micro-scale organic matter that would otherwise accumulate.
<\/li>\n\n\n\n
By occupying available ecological space and consuming shared organic nutrients, Bacillus<\/em> strains help stabilize microbial communities on treated surfaces. This reduces microbial volatility and fosters a more consistent surface ecosystem, without exerting direct selective pressure or antimicrobial activity.
<\/li>\n\n\n\n
The enzymatic degradation of odor-releasing compounds (e.g., fatty acids, ammonia, sulfur compounds) by Bacillus<\/em> results in less volatile, non-odorous byproducts (e.g., CO\u2082, water, organic acids). In combination with ecological surface balance, this contributes to sustained odor control without masking agents.<\/li>\n<\/ol>\n\n\n\n![\"\"](\"https:\/\/www.provilan.com\/wp-content\/uploads\/2025\/04\/CrolleAgency_Provilan-171-sur-250-1024x683.jpg\")
