The results of investigations on the morphology, physiology, pigment composition, light-harvesting antenna and reaction center organization, and electron carriers of five Erythromicrobium representatives, and on phylogenetic relations among them, are summarized. On the basis of clear phenotypic differences and distinct phylogenetic positions shown by 16S(More)
The sequences of the 16S rRNA gene of 40 strains of bacterial symbionts isolated from the nematodes Heterorhabditis spp. and seven bacterial symbionts of the nematodes Steinernema spp. which were isolated from different geographical areas, as well as the type strain of Xenorhabdus japonicus, were determined and compared to each other and to the sequences of(More)
β-keto esters are used as precursors for the synthesis of β-amino acids, which are building blocks for some classes of pharmaceuticals. Here we describe the comparison of screening procedures for hydrolases to be used for the hydrolysis of β-keto esters, the first step in the preparation of β-amino acids. Two of the tested high throughput screening (HTS)(More)
We present a model for electron scattering off nuclei and photon absorption in the resonance energy region (W ≦ 2 GeV). The elementary γ/γ ⋆ N-vertex is described using in-medium kine-matics and up-to-date form factors for QE-scattering, π-production form-factors and resonance helicity amplitudes of the MAID analysis. We find good agreement with inclusive(More)
Current long baseline (LBL) experiments aim at measuring neutrino oscillation parameters with a high precision. A critical quantity is the neutrino energy which can not be measured directly but has to be reconstructed from the observed hadrons. A good knowledge of neutrino-nucleus interactions is thus necessary to minimize the systematic uncertainties in(More)
In the present paper we investigate a method to describe low-energy scattering events of pions and nuclei within a Boltzmann-Uehling-Uhlenbeck (BUU) transport model. Implementing different scenarios of medium modifications, we studied the mean free path of pions in nuclear matter at low momenta and compared pion absorption simulations to data. Pursuing(More)
