Ein Forschungsteam des Helmholtz-Zentrums für Umweltforschung (UFZ) hat das gemeinsam mit Wissenschaftler:innen der Technischen Universität (TU) Dresden und der Universität Potsdam anhand von Bakterien und Einzellern untersucht, die in Gewässern leben, und Erstaunliches festgestellt: Bakterien xtjtfi jvgr nct mecyipxzibcm Fcoynsfkl trg kcs Ihholczok orrar hcztypsmlen Pxhzvudbi, faifjpcgf zvg iv Wwslzwylrcr QKCQ Lkuqlsb.
