The contamination of agricultural lands by pesticides is a serious environmental issue. Consequently, the development bioremediation methods for different active ingredients, such as pyrethroids, essential. In this study, enantioselective biodegradation (±)-lambda-cyhalothrin ((±)-LC) marine-derived fungi was studied. Experiments were performed with strains (Aspergillus sp. CBMAI 1829, Acremonium 1676, Microsphaeropsis 1675 and Westerdykella 1679) in 3% malt liquid medium 100 mg L-1 (±)-LC....
Dihydropinidine is a piperidine alkaloid found in spruce needles that has shown promising antifeedant activity against the large pine weevil, widespread and economically relevant pest of coniferous tree plantations. Chemo-enzymatic approaches have previously been to enable step-economic access both enantiomers this alkaloid, but scalability these syntheses limited. Herein, we report chemo-enzymatic route dihydropinidine dominated by biocatalytic steps affords target excellent stereoisomeric...
The growth and biodegradation potential of marine-derived fungi were evaluated by measuring the radial colonies.It was observed that Penicillium raistrickii CBMAI 931, Aspergillus sydowii 935, Cladosporium sp.CBMAI 1237, Microsphaeropsis sp.Dr(A)6, Acremonium sp.Dr(F)1, Westerdykella sp.Dr(M2)4 sp.Dr(M2)2 able to grow develop in presence pyrethroid insecticide esfenvalerate (S,Sfenvalerate) its main metabolites (3-phenoxybenzaldehyde, 3-phenoxybenzoic acid, 3-phenoxybenzyl alcohol...
Abstract Oleate hydratases (Ohys, EC 4.2.1.53) are a class of enzymes capable selective water addition reactions to broad range unsaturated fatty acids leading the respective chiral alcohols. Much research was dedicated improving applications existing Ohys as well identification undescribed with potentially novel properties. This study focuses on latter by exploring genus Rhodococcus for its plenitude oleate hydratases. Three different clades showed presence whereby each clade represented...
Several marine-derived fungi were evaluated by the bioreduction of 2-azido-1-phenylethanone 1, and strains A. sydowii CBMAI 935 M. racemosus 847 selected for reduction derivatives 2–4. Whole cells promoted 2-azido-1-phenylethanones 1–4 with high selectivities to yield (S)-2-azido-1-phenylethanols 1a–4a. Bioreduction compounds led (R)-2-azido-1-phenylethanols 2 4 (S)-2-azido-1-phenylethanol 3. Enantiomerically enriched 2-azido-1-phenylethanols 1a–4a phenylacetylene 5 applied in synthesis...
Abstract The C12 specific oxidation of hydroxysteroids is an essential reaction required for the preparation pharmaceutical ingredients like ursodeoxycholic acid (UDCA) and chenodeoxycholic (CDCA), which can be synthesized by Wolff‐Kishner reduction obtained 12‐oxo‐hydroxysteroids. 12α‐hydroxysteroid dehydrogenases (12α‐HSDHs) have been shown to perform this with high yields, under mild conditions without need protection deprotection steps, in chemical synthesis. Here, recombinant expression...
Abstract This paper reports the enantioseparation of β‐hydroxy‐1,2,3‐triazole derivatives, which present a broad range biological properties, by supercritical fluid chromatography (SFC) and high‐performance liquid techniques (HPLC). Polysaccharide‐based chiral columns (cellulose amylose) were used to evaluate separation in SFC HPLC. Time analyses, consumption solvent, parameter optimization reduced using technique. The based on cellulose stationary phase 2‐propanol ethanol as modifiers...
Abstract The implementation of a stereoselective Michael addition with water as substrate is still major challenge by classical, chemical means. Inspired nature's ability to carry out this attractive reaction both high selectivity and efficiency, the interest in hydratases (EC 4.2.1.x) accomplish selective steadily rising. gram‐positive bacterial genus Rhodococcus known biocatalytic powerhouse has been reported hydrate various acceptors leading chiral alcohols. This study aimed at in‐depth...
Palm biomass (Archontophoenix alexandrae) is a natural crop of the food industry, even with high potential to produce sustainable and innovative products. Thus, purpose this work was evaluate effect sequential acid-alkali treatment followed by precipitation concentrated H2SO4 on fiber’s microstructure, chemical, physical properties. So, raw fiber, pre-treated precipitated lignin were characterized scanning eléctron microscopy (SEM), X-ray diffraction (XRD), Fourier-transform infrared (FTIR)...
Na perspectiva de contribuir com o fortalecimento do Sistema Nacional Meio Ambiente (SISNAMA), para que se torne mais robusto, faz-se necessária a articulação entre os três níveis governo, Federal, Estadual e Municipal, deverão, instituir implementar seus Sistemas Ambiente, constituídos pelas unidades executivas responsáveis pela gestão ambiental, isto é, respectivos Conselhos Fundos Ambiente.O campo atuação dos municípios na área ambiental é bastante diversificado complexo, exigindo órgãos...
