Chromate reduction by cell-free extract of Bacillus firmus KUCr1.
Microbial enzymatic reduction of a toxic form of chromium [Cr(VI)] has been considered as an effective method for bioremediation of this metal. This study reports on the in vitro reduction of Cr(VI) using cell-free extracts from a Cr(VI) reducing Bacillus firmus KUCr1 strain. Chromium reductase was found to be constitutive and its activity was observed both in soluble cell fractions (S12 and S1...
متن کاملSubstrate-binding site of family 11 xylanase from Bacillus firmus K-1 by molecular docking.
The three-dimensional structure (3D structure) of Xyn11A, a family 11 xylanase from Bacillus firmus K-1, was obtained through homology modeling. To study the substrate-binding site of Xyn11A, six xylooligosaccharides, xylobiose to xyloheptaose (X2-X7), were docked into the active site of Xyn11A by molecular docking. Based on the docked energy and estimated free energy of binding combined with m...
متن کاملJuvenile hormone titer and morph-specific reproduction in the wing-polymorphic cricket, Gryllus firmus.
Juvenile hormone titers and reproductive characteristics were measured in adult wing and flight-muscle morphs of the wing-polymorphic cricket, Gryllus firmus, during the first week of adulthood. This species has three morphs: one flight capable morph with fully-developed wings and fully-developed flight muscles [LW(F)], one flightless morph with fully-developed wings and histolyzed (non-functio...
متن کاملGrowth and bioenergetics of alkaliphilic Bacillus firmus OF4 in continuous culture at high pH.
The effect of external pH on growth of alkaliphilic Bacillus firmus OF4 was studied in steady-state, pH-controlled cultures at various pH values. Generation times of 54 and 38 min were observed at external pH values of 7.5 and 10.6, respectively. At more alkaline pH values, generation times increased, reaching 690 min at pH 11.4; this was approximately the upper limit of pH for growth with doub...
متن کاملStructure of a mosaic hybrid zone between the field crickets Gryllus firmus and G. pennsylvanicus
Hybrid zones provide insight into the nature of species boundaries and the evolution of barriers to gene exchange. Characterizing multiple regions within hybrid zones is essential for understanding both their history and current dynamics. Here, we describe a previously uncharacterized region of a well-studied hybrid zone between two species of field crickets, Gryllus pennsylvanicus and G. firmu...
