Humic acids (HAs) possess diverse functionalities, endowing them with multiple applications as bioactive compounds in agriculture. Alkaline extraction is key to obtaining HAs from their source material. The presence of oxygen during can lead oxidative changes the humic structure. extent HA transformation depending on origin remains poorly understood, and effect alkaline biological activities yet be estimated. Here, we compare physicochemical properties extracted fresh organic material,...
A new approach to performing an accelerated sequential extraction of trace elements from solid samples has been proposed. It shown that rotating coiled columns (RCC) earlier used in counter-current chromatography can be successfully applied the dynamic leaching heavy metals soils and sediments. sample was retained column as stationary phase under action centrifugal forces while different eluents (aqueous solutions complexing reagents, mineral salts acids) were continuously pumped through....
'Large' and 'small' fractions of laccase were found in the thalli lichens Solorina crocea Peltigera aphthosa. In both lichens, 'large', possibly dimeric, laccases determined as 175 165 kDa (based on gel filtration data), ones 76 97 (according to sodium dodecyl sulfate-polyacrylamide electrophoresis respectively. By their substrate specificity, pH optima, thermostability, they typical laccases. The 45 from S. 55 P. aphthosa consisted two enzymes.
Abstract Soil organic matter (SOM) turnover by ligninolytic fungi is a large‐scale process that controls carbon geochemistry in terrestrial ecosystems. However, the role of certain oxidative enzymes (e.g., laccase) humus degradation remains unclear, as well molecular structure and recalcitrance SOM components. In order to address these questions, forest soil humic acid (HA) presence laccase versatile peroxidase (VP) has been studied liquid culture Lentinus tigrinus . Contrary evolving views...
Biochemical stability of soil humus is an important factor affecting quality. Fungi are among the most efficient decomposers humic matter due to presence oxidative enzymes, including phenoloxidase laccase. Production laccase by zygomycetes, a group cellulolytic fungi widespread in soil, poorly studied. The potential role from zygomycetes turnover unknown. Here, we show for first time that zygomycetous fungus Mortierella elasson can effectively depolymerize acids vitro. produced...
Abstract Soil organic matter (SOM) is the largest reservoir of carbon in biosphere. However, little known about processes its formation at pre‐vascular stage. Lichens are among pioneer colonizers on mineral substrates and possible early land flora. This study first report identification quantification water‐soluble phenolic compounds (PCs), potential precursors humic substances, epigeyic lichens from two systematic groups. Results show (Folin–Denis assay) that cyanobiont‐containing (order...
