Effects of hydrochloric acid washing on the microstructure and pyrolysis bio-oil components of sweet sorghum bagasse

Acid washing is an alternative and promising approach for biomass to produce high-quality bio-oil. The hydrochloric acid washing pretreatment of sweet sorghum bagasse was performed in this study. The effects of acid washing on the ultrastructure of sweet sorghum bagasse were investigated using scanning electron microscope and Fourier transform infrared, and the effects on pyrolysis using thermogravimetric analyzer and a fast pyrolysis device. The results indicated acid treatment obviously changed the surface morphology of the cell walls of sweet sorghum bagasse, effectively removed most metals from sweet sorghum bagasse, and increased the volatiles and bio-oil yields. The results showed that bio-oil produced from pretreated sweet sorghum bagasse contained less components categories, lower contents of phenols, aldehydes, furans and alcohols, while much higher contents of d-allose and ketones than that from the original sample. Hydrochloric acid-washing pretreatment of sweet sorghum bagasse can increase the contents of some high-value chemicals in bio-oil.

Growth media affect the volatilome and antimicrobial activity against Phytophthora infestans in four Lysobacter type strains

Bacterial volatile organic compounds (VOCs) play important ecological roles in soil microbial interactions. Lysobacter spp. are key determinants of soil suppressiveness against phytopathogens and the production of non-volatile antimicrobial metabolites has been extensively characterised. However, the chemical composition and antagonistic properties of the Lysobacter volatilome have been poorly investigated. In this work, VOC emission profiles of four Lysobacter type strains grown on a sugar-rich and a protein-rich medium were analysed using solid-phase microextraction gas chromatography?mass spectrometry and proton transfer reaction-time of flight-mass spectrometry. Lysobacter antibioticus, L. capsici, L. enzymogenes and L. gummosus type strains were recognised according to their volatilome assessed using both headspace mass spectrometry methods Moreover, the chemical profiles and functional properties of the Lysobacter volatilome differed according to the growth medium, and a protein-rich substrate maximised the toxic effect of the four Lysobacter type strains against Phytophthora infestans. Antagonistic (pyrazines, pyrrole and decanal) and non-antagonistic (delta-hexalactone and ethanol) VOCs against Ph. infestans or putative plant growth stimulator compounds (acetoin and indole) were mainly emitted by Lysobacter type strains grown on protein- and sugar-rich media respectively. Thus nutrient availability under soil conditions could affect the aggressiveness of Lysobacter spp. and possibly optimise interactions of these bacterial species with the other soil inhabitants.

On the regioselectivity of Wittig reactions with unsymmetrically substituted succinic anhydrides

Phosphorane ylids react readily with succinic anhydrides to give enol-lactones.With highly substituted succinic anhydrides, condensation occur at the less substituted carbonyl group, suggesting that the reaction is sterically controlled.This, however, is not the case in monosubstituted anhydrides where effects other than steric become dominant.Condensation of phosphorane 1a with methoxysuccinic anhydride occurs selectively at the carbonyl group adjacent to the substituent.Stabilization of the transition state through complexation between the oxygen atom of the substituent and an electron-deficient phosphorus of the ylid is proposed.Key words: cyclic anhydrides; Wittig reaction, regioselectivity; stabilized ylid.

Synthesis of perfluorinated analogs of DOTA and NOTA: Bifunctional chelating groups with potential applications in hybrid molecular imaging

The synthesis of novel NOTA (1,4,7-triazacyclononane-1,4,7-triacetic acid) and DOTA (1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid) chelating groups bearing perfluorinated appendages is described. DOTA and NOTA groups are used in the production of radiopharmaceutical agents for PET and SPECT imaging (by chelation of radioactive metal ions), as well as MRI contrast agents (by chelation of lanthanide Ln3+ ions). The novel perfluorinated variants disclosed herein will enhance the synthesis and purification of such agents, as they are compatible with fluorous purification strategies. Moreover, the perfluorous tag is anticipated to be detectable by 19F-MRI, suggesting future applications in hybrid molecular imaging such as PET-MRI.
