A simple membrane dialysis bioreactor was developed for a large-scale axenic culture of Symbiobacterium thermophilum, a symbiotic thermophile that requires co-cultivation with an associating thermophilic Bacillus strain S for normal growth. The bioreactor consisted of an outer- and an inner-coaxial cylindrical compartment bordered across a dialyzing(More)
Mouse cytotoxic T-lymphocyte antigen-2α (CTLA-2α), Drosophila CTLA-2-like protein (crammer), and Bombyx cysteine protease inhibitor (BCPI) belong to a novel family of cysteine protease inhibitors (I29). Their inhibitory mechanisms were studied comparatively. CTLA-2α contains a cysteine residue (C75), which is essential for its inhibitory potency. The(More)
We have prepared four new Cu(II) complexes containing valine moieties with imidazole ligands at the fourth coordination sites and examined their photo-induced reactions with TiO2 in order of understanding the reaction mechanisms. Under a nitrogen atmosphere, the intermolecular electron transfer reactions (essentially supramolecular interactions) of these(More)
