Seven derivatives of plant-derived hydroxybenzoic acid (HBA)—including 2,3-dihydroxybenzoic (2,3-DHB, pyrocatechuic), 2,4-dihydroxybenzoic (2,4-DHB, β-resorcylic), 2,5-dihydroxybenzoic (2,5-DHB, gentisic), 2,6-dihydroxybenzoic (2,6-DHB, γ-resorcylic acid), 3,4-dihydroxybenzoic (3,4-DHB, protocatechuic), 3,5-dihydroxybenzoic (3,5-DHB, α-resorcylic), and 3,4,5-trihydroxybenzoic (3,4,5-THB, gallic) acids—were studied for their structural biological properties. Anti-/pro-oxidant properties were...
The structure of the Zn(II) complex 5-caffeoylquinic acid (chlorogenic acid, 5-CQA) and type interaction between cation ligand were studied by means various experimental theoretical methods, i.e., electronic absorption spectroscopy UV/Vis, infrared FT-IR, elemental, thermogravimetric density functional theory (DFT) calculations at B3LYP/6-31G(d) level. DPPH (2,2-diphenyl-1-picrylhydrazyl), ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid), FRAP (ferric reducing antioxidant power),...
Caffeic acid (CFA) is one of the various natural antioxidants and chemoprotective agents occurring in human diet. In addition, its metal complexes play fundamental roles biological systems. Nevertheless, research on properties CFA with lanthanide metals very scarce, little to no chemical or information known about these particular Most their properties, including activity environmental impact, strictly depend structure, stability, solution behaviour. this work, a multi-analytical-technique...
The main objective of this work was to determine the abundance and species diversity fungi in waters selected rivers Central Europe, NE Poland (Augustów Lakeland), differing size, physical chemical properties, streamflow rate. minimum analysed recorded for a river with low concentration organic matter (8200 CFU/mL, Czarna Hańcza River), maximum strongly anthropogenically polluted (24,800 Kamienny Bród River). A total 49 fungal were identified based on PCR ITS-RFLP DNA sequencing methods....
Abstract Leachate from landfills is a product of complex biological and physicochemical processes occurring during waste storage. In the present study, toxicity landfill leachate (LL) to human bacterial cells was investigated for better understanding LL environmental toxicity. Studies regarding properties cytotoxicity analysis were conducted. Escherichia coli , Pseudomonas fluorescens Bacillus subtilis fibroblasts melanoma A-375 cells, cell viability assays applied. For determination...
The present study was undertaken to test the influence of exogenously applied traumatic acid (TA) upon activity several antioxidant enzymes as well lipid and protein peroxidation in green algae Chlorella vulgaris. Treatment with TA concentration range 10−6–10−5 M resulted an increase enzyme (sodium dismutase, catalase, ascorbate peroxidase, NADH glutathione reductase) activity. Moreover, suppressed oxidative destruction proteins belonging SH groups. This data suggest that plays important...
The aim of this work was to study the role traumatic acid (TA) in adaptation green algae Chlorella vulgaris Beijerinck salt stress. In order achieve aim, studies were conducted concerning influence exogenous TA at a concentration 10−5 M combined with sodium chloride (NaCl) various concentrations (10−7–10−4 M), on growth C. and levels basic biochemical parameters, such as chlorophylls b, monosaccharides, cell proteins activity superoxide dismutase enzyme. carried out demonstrated that...
One of the solutions implemented in order to improve quality soils exposed pesticides is application sewage sludge, which a by-product wastewater treatment. As an organic substrate, it provides soil with important nutrients, such as nitrogen and phosphorus, enriches matter, thanks can be valuable fertilizer. The aim presented research was evaluate influence granulated sludge (GSS) on biological properties treated herbicides (MCPA dicamba) fungicides (thiophanate-methyl azoxystrobin)....
Deep chlorophyll maxima (DCM) are a common phenomenon in low-trophic stratified lakes, and there is much less information about the occurrence of DCM eutrophic dystrophic lakes. Therefore, we performed situ continuous measurements concentration by submersible spectrofluorometer 23 temperate lakes with different trophic conditions (mesotrophic, eutrophic, dystrophic). We perform chemical analyses available nutrient forms to better understand mechanism formation. found highest phytoplankton...
This paper presents the results of a study effects lanthanide ions Ce3+, Pr3+, Nd3+ and Sm3+ on electronic structure antioxidant biological (antimicrobial cytotoxic) properties p-coumaric acid (p-CAH2). Structural studies were conducted via spectroscopic methods (FTIR, ATR, UV). Thermal degradation complexes performed. The are presented in form TG, DTG DSC curves. Antioxidant determined activity tests against DPPH, ABTS OH radicals. reducing ability was tested CUPRAC assays. Minimum...
Abstract The objective of the paper was to determine influence iron(III) ions on growth and metabolism fungi commonly occurring in waters: yeast Rhodotorula mucilaginosa filamentous fungus Cladosporium herbarum . Cells R were shown absorb most at a concentration 1 mg/L ions. Yeast cells showed considerable increase content proteins monosaccharides, as well biomass growth. At higher concentrations ions, limited intake decrease basic metabolites observed, an secretion such into medium....
In this study, we investigated the structures of lanthanide (Eu(III), Dy(III), and Gd(III)) complexes with p-coumaric (p-CAH2) caffeic (CFAH3) acids using FTIRKBr, FTIRATR, Raman spectroscopic methods. The compositions solid phase caffeinates p-coumarates were obtained on basis amounts hydrogen carbon determined an elemental analysis. degree hydration thermal decomposition each compound examined via a analysis TG, DTG, DSC. Antioxidant tests performed DPPH (1,1-diphenyl-2-picrylhydrazyl...

Abstract The effect of exogenous traumatic acid, (2E)-dodecene-1,12-dioic acid (TA), at concentrations 10 -6 - -3 M on the growth and development unicellular green alga Chlorella vulgaris was examined over 7 days. TA plays an important role in algal development. Treatment with -5 resulted greatest increase cell numbers, by 77%, chlorophyll a content, 126%, b , 45%, total carotenoids, 65%, monosaccharides, 111%, water-soluble proteins, 37%, relation to control. After three days treatment...
Abstract The research presented here was conducted in order to determine the influence of exogenous traumatic acid (TA) on growth, metabolism, and antioxidative activity vascular water plant, Wolffia arrhiza Wimm. concerned with TA influences, concentrations 10−8 M − 10−4 M, fresh W. arrhiza, primary metabolites, such as monosaccharides, proteins, chlorophylls a b, carotenoids.
