Die Tiefsee ist der größte und am wenigsten erforschte Lebensraum der Erde. Dort hat Gerhard J. Herndl, Meeresbiologe an der Universität Wien, erstmals Bakterien entdeckt, die wie Pflanzen das Enzym Ribulose-Biphosphat-Karboxylase (RuBisCO) besitzen. Dieses Enzym spielt bei der Photosynthese der Pflanzen eine wichtige Rolle, sie wandeln damit Kohlendioxid in organischen Kohlenstoff und Biomasse um. Bei den neu entdeckten Tiefsee-Bakterien dient jedoch nicht Sonnenlicht als Energiequelle, sondern sie ernähren sich von Schwefelverbindungen. Zu den aktuellen Forschungsergebnissen publizieren die ForscherInnen der Universität Wien zusammen mit KollegInnen aus den USA in der renommierten Fachzeitschrift "Science".
