Regulation and characterization of the nitrogen assimilatory gene cluster in Clostridium acetobutylicum P262
Published 2023“…The identity of the gltA and gltB genes were functionally confirmed by complementation studies involving their co-expression from separate constructs in an E. coli glutamate auxotroph (strain: Mx:3004), which restored the ability of this mutant to grow with ammonia as the sole source of nitrogen. …”

Exploring the factors at play to make wastewater biorefineries a reality
Published 2019“…Each reactor group is considered in detail and evaluated with regards to its suitability to the wastewater biorefinery, leading to selection of appropriate reactor designs. Stoichiometric mass balances of all unit operations are established, showing the material value flows, and combined to model this multi-bioreactor approach. …”

Peculiar flow fields in the zone of avoidance from the near-infrared Tully-Fisher relation
Published 2017“…We also simulate the effect of dust extinction on the shape of galaxies and derive a correction model. We show the ability of this model to reproduce the intrinsic axial ratio from the observed parameters up to extinction levels of AV ~ 11 mag. …”

A geochemical and stable isotope study of some rocks from the Bandelierkop formation, southern marginal zone of the Limpopo Belt, South Africa( vol.1 Text)
Published 2017“…Peak metamorphic conditions of 730°C + 65°C at pressures of 6.1 ± 1.5 kbars may be deduced from a careful application of several cation thermometers and barometers on selected mineral analyses. A rigorous application of garnet-biotite thermometry to the pelitic rocks indicates that the transition from orthoamphibole gneisses in the south to orthopyroxene-bearing rocks in the north of the SMZ terrane, is a function of changing biotite composition and/or decreasing water activities rather than an increase in metamorphic temperatures. …”

From proteomics to biotechnology. using the resurrection plant eragrostis nindensis to genetically engineer drought tolerant crops
Published 2026“…Of great relevance are regionally adapted crops, known as orphan crops, which tend to have very little economic value but can provide a source of alternative food security. Vegetative desiccation tolerance is a remarkable feat of selective evolution and is only present in a small number of angiosperms. …”
