In the present study, we aimed to obtain a high yield and productivity for glucosamine using a low-cost solid-state culture with Aspergillus sydowii BCRC 31742. The fermentation conditions, such as inoculum biomass, moisture content, and supplemental volume and mineral salt, were chosen to achieve high productivity of glucosamine (GlcN). When the initial supplemental volume used was 3 mL/g substrate, the yield and productivity of GlcN were 48.7 mg/gds and 0.69 mg/gds·h, respectively. This result will be helpful for the industrialization of the process.

Computational Strategy

ABSTRACTRuthenium-nitrosyl (RuII(NO)) complexes are stable in the dark, but exhibit a unique photoreactivity which can lead either to a solid state isomerization from RuII(NO) to RuII(ON), or to a nitric oxide (NO·) release in solution. From our recent discovery of a high yield of isomerization (> 92%) in [RuII(py)4Cl(NO)](PF6)2, we have developed a computational strategy aimed at designing switchable nonlinear optical (NLO) material with high contrast (large difference in the on / off NLO response) in the solid state. Our synthetic targets are terpyridine based RuII chromophores in which various substituents can be introduced to adjust the NLO response which, at best, should be vanishing in the off state. Alternatively, these complexes can undergo a photo-induced NO· release in solution, a possibility which becomes increasingly appealing in relation to the discovery of the numerous biological roles of NO·, in the context of the emergence of the photodynamic therapy. A promising fluorene-terpyridine RuII(NO) complex was investigated, which could find an additional interest in relation to its capability for releasing NO· by a two-photon absorption process.

Bromide Solutions

In spite of the extensive and diversified uses of wood and wood products for millenia, there are still a number of basic deficiencies of these pro ducts which limit their use and pose difficult and as yet not satisfactorily solved problems to the engineer and consumer. The most prominent of these problems are: flammability, dimensional stability, and fungal attack. Review of work carried out at the Israel Fiber Institute indicates that treating solid timber and polywood with acidified bromate-bromide solutions is capable of overcoming these deficiencies to a large extent. The treatment is carried out in autoclaves with application of vacuum and pressure. The lignin component of the wood is brominated in the solid state by the treatment solution with a high yield of bromine. The mechanical properties of the treated products are un changed. The treatment is stable to prolonged leaching, aging, and storage. Water absorption and swelling are drastically decreased-dimensional stabi lization. The brominated products are shown not to be attacked by wood fungi.

Exclusive, high-yield formation of the cyclotrimers of ethynylferrocene (1) was observed when TaCl5 in benzene was employed as catalyst. Analysis of the resulting isomer mixture by means of HPLC and 1H NMR revealed the presence of 1,3,5-triferrocenylbenzene (sym-2) and 1,2,4-triferrocenylbenzene (asym-2) in the ratio of 4 : 6. A small amount of pure sym-2 isomer was isolated, and its solid-state structure was established by single-crystal X-ray diffraction. The molecules of sym-2 possess a distorted up-up-down arrangement of the ferrocenyl groups attached to the benzene ring.

Malaysia is the largest country that has produced many types of waste. One of it is Meranti wood sawdust. These wastes result in a significant environmental problem if not dispose it in the proper manner. The main objective of this article is to produce the high yield of sorbitol by solid state fermentation (SSF) process from pretreated Meranti wood sawdust using bacterium Lactobacillus plantarum (BAA 793; NCIMB 8826). One factorat a time (OFAT) was studied for further process using solid state fermentation (SSF) process and investigated the effect of relevant parameters (fermentation time, range: 2 hours to 14 hours, moisture content, range: 40% to 90%, temperature, range: 25 oC to 45 oC) to the solid-state fermentation (SSF) process in producing high yield of sorbitol. The highest product yield was obtained at 50% moisture content, at 10 hours of fermentation time and 35 oC of incubation temperature where the concentration of sorbitol was 25.68 g/L respectively. This study also showed that the solid state fermentation (SSF) process will produce the high yield of sorbitol production compared to the submerged fermentation and could serve as a-low cost substrate for bioproducts production especially sorbitol

The One

New synthetic routes to aerobically stable and substitutionally labile a-diimine rhenium(I) dicarbonyl complexes are described. The molecules are prepared in high yield from the cis-cis-trans-[Re(CO)2(tBu2bpy)Br2]- anion (2, where tBu2bpy is 4,4'-di-tert-butyl-2,2'-bipyridine), which can be isolated from the one electron reduction of the corresponding 17-electron complex (1). Compound 2 is stable in the solid state, but in solution it is oxidized by molecular oxygen back to 1. Replacement of a single bromide of 2 by s-donor monodentate ligands (Ls) yields stable neutral 18-electron cis-cis-trans-[Re(CO)2(tBu2bpy)Br(L)] species. In coordinating solvents like methanol the halide is replaced giving the corresponding solvated cations. [Re(CO)2(tBu2bpy)Br(L)] species can be further reacted with Ls to prepare stable cis-cis-trans-[Re(CO)2(tBu2bpy)(L)2]+ complexes in good yield. Ligand substitution of Re(I) complexes proceeds via pentacoordinate intermediates capable of Berry pseudorotation. In addition to the cis-cis-trans-complexes, cis-cis-cis- (all cis) enantiomers are also formed. In particular, cis-cis-trans-[Re(CO)2(tBu2bpy)(L)2]+ complexes establish an equilibrium with all cis enantiomers in solution. The solid state crystal structure of nearly all molecules presented could be elucidated. The molecules adopt a slightly distorted octahedral geometry. In comparison to similar fac-[Re(CO)3]+complexes, Re(I) diacarbonyl species are characterized by a bend (ca. 7°) of the axial ligands towards the a-diimine unit. [Re(CO)2(tBu2bpy)Br2]- and [Re(CO)2(tBu2bpy)Br(L)] complexes may be considered as synthons for the preparation of a variety of new stable diamagnetic dicarbonyl rhenium cis-[Re(CO)2]+ complexes, offering a convenient entry in the chemistry of the core.
