Der vermeintlich \u201erutschige Schimmel\u201c ist in den meisten F\u00e4llen gar kein Pilz, sondern ein Bakterien-Biofilm \u2013 meist verursacht durch das Bakterium Serratia marcescens<\/em><\/strong> (oder Hefepilze wie Rhodotorula<\/em>). Es bildet auf feuchten Oberfl\u00e4chen im Bad einen charakteristischen rosa, orangefarbenen oder gelblichen, glitschigen Belag.<\/p>\n\n\n\n
