Largely unquenched Re 5d orbital magnetic moments in half-metallic Ba2FeReO6 drive a symmetry lowering transition from a cubic paramagnet to a compressed tetragonal (c/a < 1) ferrimagnet below Tc ~ 305 K, with a giant linear magnetoelastic constant and the spins lying spontaneously along the unique tetragonal axis. The large orbital magnetization and degree of structural deformation indicate pr...

Single-crystal high-pressure X-ray diffraction studies on the protein crystals of orthorhombic and tetragonal hen egg-white lysozyme polymorphs were carried out using a Merrill-Bassett diamond-anvil cell, image-plate detector and synchrotron radiation. The orthorhombic crystal has been squeezed to 85.5% of its ambient pressure volume at about 1.0 GPa; the crystal compresses anisotropically, and...

An in vivo experiment was conducted to study the effects of probiotic Bacillus coagulans spores, with and without prebiotic, inulin, on gastrointestinal (GI) microbiota of healthy rats and its potentiality to survive in the GI tract. Forty-eight male Wistar rats were randomly divided into four groups (n=12) and fed as follows: standard diet (control), standard diet supplied with 5% w/w long cha...

We studied the effects of combinations of Bacillus thuringiensis spores and toxins on the mortality of diamondback moth (Plutella xylostella) larvae in leaf residue bioassays. Spores of B. thuringiensis subsp. kurstaki increased the toxicity of crystals of B. thuringiensis subsp. kurstaki to both resistant and susceptible larvae. For B. thuringiensis subsp. kurstaki, resistance ratios were 1,20...

The aim of this work is to demonstrate the role of conidial spores as a reservoir of glucose oxidase and their stability as a biocatalyst in the bioconversion reaction for the production of gluconic acid. Solid-state fermentation (SSF) was carried out in fixed-bed column bioreactor for the production of Aspergillus niger spores. Growth parameters, sporulation and kinetics of gluconic acid produ...

Introduction Spores of Bacillus and Clostridium species are metabolically dormant and extremely resistant to acute environmental stresses such as heat, desiccation, UV and γ-radiation, mechanical disruption, enzymatic digestion and toxic chemicals. In addition to the spore’s resistance to acute stress, spores can survive for extremely long periods in milder environmental conditions. Indeed, the...

No occurrence of milky disease resulted when third-instal' larvae of the Japanese beetle, Popillia iaponica, were exposed to soil containing 2 billion spores/kg of strain NRRLB-2.309l'vI of tile milky disease bacterium, Bacillus popilliae, produced on a laboratory medium, or when the larvae imbibed 200,000 of the spores of strain NRRL B-2309M in aqueous suspension; however, 24% of the larvae we...
