Incollaboration with Ivan Berg (Univ. Münster), we were able to provide definitive proof for the existence and biochemical activity for four crucial enzymes involved in the unusual carbon fixation cycle (DC/HB cycle) in Ignicoccus cells, and in particular their subcellular distribution: NO, they are NOT present in the "central cytoplasmic compartment", but in the "peripheric cytoplasmic compartment", close to the outer cytoplasmic membrane. In contrast, DNA, RNA, and protein synthesis are all found in the central compartment, only. Thus, there is a need to understand the transport of proteins and metabolites, crossing the inner cytoplasmic membrane. - This paper was published in the Proceedings of the National Academy of Sciences USA.



JUNE 2021
In collaboration with researchers from the University Hospital Regensburg, we investigated on interactions of carbonate and phosphate ions with flavin photosensitizers and the implications for bacterial inactivation.

Power-to-Gas is one of the promising technologies to transform energy systems towards renewable generation. In this paper, we describe the fully automated process of the ORBIT trickle-bed reactor, which we developed in only 3 years from lab scale to field test level. The methanation reaction is catalyzed by a pure culture of Methanothermobacter thermoautrotrophicus IM5 that was isolated many years ago at our Institute.

In this review published in Journal of Molecular Biology, we discuss single-molecule approaches suitable to examine molecular mechanisms of transcription and highlight findings that shaped our understanding of the archaeal transcription apparatus. We furthermore explore the possibilities and challenges of next-generation single-molecule techniques, for example, super-resolution microscopy and single-molecule tracking, and ask whether these approaches will ultimately allow us to investigate archaeal transcription in vivo.

Power-to-Gas technology has been recognized globally as one of the key elements for the transition towards a sustanaible energy system. However, studies on biological CO2-methanation as one part of this technology are difficult to compare since they lack a coherent nomenclature. In this article, we attempt to set standards for a comprehensive description of biological methanation processes including not only technical but also microbiological parameters.
May 2019

The joint project ORBIT reached an important milestone: at a news conference at the OTH Regensburg, the trickle-bed bioreactor of the project was initially operated by inoculation with methanogenic archaea. Aim of this innovative research facility is to produce “green methane” out of power from renewable energies. During the next year, Andrea Böllmann and Annett Bellack will analyze and optimize the efficiency of the microorganisms to produce high-quality methane, which should be directly fed into the gas grid in the next step of the project.

The most conserved initiation factor is the TATA-binding protein (TBP), which is of crucial importance for all archaeal-eukaryotic transcriptioninitiation complexes. Recent structural, biochemical and genome-wide mapping data showed that the functional importance of TBP in the RNAP I system is divergent from the canonical role TBP plays in RNAPII transcription. Here, we review the role of TBP in the different transcription systems including a TBP-centric discussion of archaeal andeukaryotic initiation complexes.

Reinhard Wirth

January 2019

We are grieving for our colleague and friend Reinhard Wirth who passed away on 3 January 2019. His untimely death cames as a shock to us.

Reinhard Wirth accepted a call to the University of Regensburg in 1994 and was a passionate scientist and teacher. Reinhard Wirth's research focused - among others - on gene transfer in and mobility of Archaea. He also isolated and characterised a number of new archaeal strains. In 2017 Reinhard retired and looked back at his career in his farewell lecture (see https://mediathek.uni-
). Since 2017, he dedicated himself to translate "the Brock" - the standard reference work for Microbiologist - into German.

Reinhard Wirth will be greatly missed and we will always remember Reinhard Wirth as a friend, mentor and colleague.
