Isolation and characterization of episulfoxides

Applying PICRUSt and 16S rRNA functional characterisation to predicting co-digestion strategies of various animal manures for biogas production

“…They are mostly pathogenic 86 , 87 Clostridium Cow < Pig < horse Most members of these species are pathogenic to animals. They are capable of converting various carbohydrates to succinate and acetate 70 , 88 Sporobacter Horse = pig Members of the genus are capable of using organic compounds in metabolism yielding acetates 89 , 90 Bacteria genera in consortia that are likely pathogenic Asaccharospora Horse One identified species Asaccharospora irregularis resembling in characteristics Clostridium irregularis described as pathogenic 70 Aerococcus Horse < cow < pig Members of the genus produce acids from a variety of carbohydrates and are directly involved in acidogenesis The KEGG pathway shows involvement of A. urinae in anaerobic energy and selenocompound metabolism. Some species are considered pathogenic 62 – 64 Acinetobacter Horse = pig < cow Most members of this genus are pathogenic and possess virulence factors but enzymes produced are also involved in amino acid, carbohydrate and lipid transport and metabolism 91 Pseudomonas Horse = pig < cow Pseudomonas spp.…”

Photoacoustic FTIR Spectroscopy, a Nondestructive Method for Sensitive Analysis of Solid-Phase Organic Chemistry

“…Treatment of 2 with 4-cyanobenzoyl chloride in the presence of triethylamine in THF−CH 2 Cl 2 afforded resino-(2 R ) -S -benzyl- N -( p -cyanobenzoyl)cysteinate 3 as determined by the appearance of the amide carbonyl band at 1674 cm -1 , the nitrile band at 2231 cm -1 , and the amide NH at 3413 cm -1 (Figure c). Oxidation of the thioether using excess m -CPBA in dichloromethane then yielded the resino sulfone 4 as observed by the appearance of the strong O=S=O stretch at 1140 cm -1 (Figure d) . The formation of resino- N -( p -cyanobenzoyl)dehydroalanine 5 on treatment of resino sulfone 4 with DBU was finally indicated by the disappearance of the sulfone stretch at 1140 cm -1 (Figure d,e) .…”

The Synthesis of [2-2H1]Thiirane-1-oxide and [2,2-2H2]Thiirane-1-oxide and the Diastereoselective Infrared Laser Chemistry of [2-2H1]Thiirane-1-oxide

“…[10] We have therefore undertaken a more detailed study of the chiral thiirane-1-oxides CH 2 CHDSO and CH 2 CD 2 SO shown in Figure 1. While ordinary thiirane-1-oxide was well characterized some time ago [11,12] and cis and trans isotopomers of CHDCHDSO have been synthesized and used for mechanistic studies on the stereochemistry of the reaction by Aalbersberg and Vollhard, [9] the title compounds of the present investigation (Figure 1) have not been prepared and investigated before. We report here their synthesis and spectroscopic characterization.…”

“…Diagram of the syntheses for ethylenecarbonates according to Daub, [17] for thiiranes according to Searles, [18,19] and the final oxidation according to Kondo. [11] gous ethylene carbonate, [17±19] from which the sulfide is prepared. Both approaches were tested in our laboratory.…”

“…From 6 b (13.2 g, 0.20 mol, 98 % purity) we obtained 7 b (16.3 g, 0.17 mol, 94 % purity, 84 % yield) as a colorless crystalline substance. [11,12] Compound 9 b was prepared according to the method used for 9 a. From 8 b (5.15 g, 82 mmol, 98 % purity) we obtained 9 b (5.2 g, 63 mmol, 95 % purity, 77 % yield) after removing the solvent on a rotary evaporator and vacuum distillation of the residues.…”
