A novel and efficient screening method for pyrroloquinoline quinone (PQQ) high-yielding methylotrophic strains was developed by using glucose dehydrogenase apoenzyme (GDHA) which depended on PQQ as the cofactor. Using this high-throughput method, PQQ high-yielding strains were rapidly screened out from thousands of methylotrophic colonies at a time. The(More)
Three ultraviolet light-emitting organic acids of 3,3′-(4-phenyl-4H-1,2,4-triazole-3,5-diyl)dibenzoic acid (Tz-1), 4,4′,4″-(4H-1,2,4-triazole-3,4,5-triyl)tribenzoic acid (Tz-2), and 4,4′-(4-(4′-carboxy-[1,1′-biphenyl]-4-yl)-4H-1,2,4-triazole-3,5-diyl)dibenzoic acid (Tz-3) were successfully synthesized and fully characterized by the 1H NMR, the IR absorption(More)
In the title rhenium(I) complex, [ReBr(C(13)H(9)N(3)O)(CO)(3)]·CH(2)Cl(2), the dichloro-methane solvent mol-ecule is disordered over two positions with an occupancy ratio of 0.81 (15):0.19 (15). The Re(I) atom is coordinated by two N atoms from a 2-phenyl-5-(pyridin-2-yl-κN)-1,3,4-oxadiazole (L) ligand, three C atoms from three carbonyl groups and a Br atom(More)
In the title compound, [ReBr(C(14)H(11)N(3)O)(CO)(3)]·CH(2)Cl(2), the coordination geometry of the Re(I) atom is a distorted ReC(3)N(2)Br octa-hedron with the carbonyl C atoms in a fac arrangement. Within the 2-(pyridin-2-yl)-5-p-tolyl-1,3,4-oxadiazole ligand, the dihedral angles between the oxadiazole ring and the pyridine (py) and benzene (bz) rings are(More)
