Globe artichoke is an intriguing source of indigestible sugar polymers such as inulin-type fructans. In this study, the effect ultrasound in combination with ethanol precipitation to enhance extraction long chain fructans from wastes has been evaluated. The content both bracts and stems was measured using enzymatic fructanase-based assay, while its average degree polymerization (DP) determined by HPLC-RID analysis. Results show that method provides extracts 70% DP between 32 42 stems....
In this paper, we demonstrate that the antimicrobial activity of L. plantarum PBS067 strain against antagonist microorganisms was mediated by production a bacteriocin-like compound secreted at stationary phase growth. The novel compound, designed plantaricin P1053, identified using sorption–desorption method, butanol extraction and SEC-HPLC. molecular mass P1053 shown to be 1053 Da ESI-MS analysis. Plantaricin exhibited broad-spectrum Gram-positive bacteria as S. aureus Gram-negative E....
ABSTRACT Pseudomonas stutzeri OX1 meta pathway genes for toluene and o -xylene catabolism were analyzed, loci encoding phenol hydroxylase, catechol 2,3-dioxygenase, 2-hydroxymuconate semialdehyde dehydrogenase, hydrolase mapped. Phenol hydroxylase converted a broad range of substrates, as it was also able to transform the nongrowth substrates 2,4-dimethylphenol 2,5-dimethylphenol into 3,5-dimethylcatechol 3,6-dimethylcatechol, respectively, which, however, not cleaved by 2,3-dioxygenase. The...
Rhodococcus members excrete secondary metabolites, especially compounds which act as biosurfactants. In this work, we demonstrated the ability of opacus R7 to produce a novel bioactive compound belonging class biosurfactants with antimicrobial properties during growth on naphthalene. Chemical and biochemical analyses isolated that biosurfactant could be classified hydrophobic peptide. The ESI-full mass spectrometry revealed showed molecular weight 1292 Da NMR spectra evidenced composition...
ABSTRACT We developed a biocatalyst by cloning the styrene monooxygenase genes ( styA and styB ) from Pseudomonas fluorescens ST responsible for oxidation of to its corresponding epoxide. Recombinant Escherichia coli was able oxidize different aryl vinyl ethenyl compounds their optically pure epoxides. The results bioconversions indicate broad substrate preference potential production several fine chemicals.
Bacteria belonging to the Rhodococcus genus play an important role in degradation of many contaminants, including methylbenzenes. These bacteria, widely distributed environment, are known be a powerhouse numerous functions, due their ability metabolize wide range organic molecules aliphatic, aromatic, polycyclic aromatic compounds (PAHs), phenols, and nitriles. In accordance with immense catabolic diversity, spp. possess large complex genomes, which contain multiplicity genes, high genetic...
The reaction of α-haloesters and carbonyl compounds in the presence metallic zinc to give β- hydroxy esters represents a powerful synthetic tool for carbon-carbon bond formation. Since its discovery by Reformatsky, this has been undergoing several improvements scope selectivity have considerably extended. To purpose many parameters, such as metal activation, temperature, solvent, properly designed reactants substrates investigated. Furthermore, reactions are not restricted use zinc, but...
α,β-Unsaturated esters were synthesized in open atmosphere via mild and efficient one-pot Wittig reactions performed both water sodium dodecyl sulfate (SDS)-water solution.

The importance and variety of glycosides in nature together with the lack a conclusive synthetic methodology prompted us to study electrochemical reductive behavior glycosyl halides generate suitable intermediates for glycosidation both aliphatic aromatic acceptors. A special case considered here is almost quantitative synthesis C‐C dimers.
This review will present recent achievements in the use of novel reactants and synthetic procedures for transformation substrates into epoxide derivatives. include both classical chemical methods using catalysts and/or cleaner methodologies, enzymatic preparations enzymes or cells. Special attention is paid to preparation chiral compounds. A comparison advantages disadvantages different also included.
