Isolation of high quality RNA from soil-grown Ilex paraguariensis roots suitable for next-generation sequencing and gene expression analyses [PDF]
, 2017 Extraction of high quality RNA is a prerequisite for downstream application in functional genomics analyses. However, the extraction and purification of pure nucleic acids from root tissues is generally difficult due to the high concentration of ...

Untangling nutrient co‐regulation of ombrotrophic peatland development
Boreas, EarlyView.Multi‐method (FTIR, FT‐NIR and TGA) approaches characterizing the organic peat constituents at Holcroft Moss reveal a record of switches that reflect broadly hydroclimate variability governing the decomposition patterns. There are periods, however, where hydroclimate does not fully explain the variability observed and instead changes appear linked to ...

Fluorescence Analysis for Multi-Site Aluminum Binding to Natural Organic Matter [PDF]
, 1998 Natural organic matter (NOM) samples isolated from different water sources in Norway were compared using their fluorescence properties. Fluorescence surfaces were observed at pH 4.36 and deconvoluted using SIMPLISMA (Windig and Guilment 1991). There were

Facilitated Transport of Organic Contaminants in a High Concentration, Multicomponent Plume
Groundwater Monitoring &Remediation, EarlyView.Abstract A field experiment evaluated the transport of organic contaminants in a plume from hazardous waste disposal areas at the Rocky Mountain Arsenal. The plume contained many xenobiotic contaminants, with widely varying expected mobilities.

Complexations of Divalent Metallic Ions with Fulvic Acids
Eclética Química, 2018 In this work, the interactions of the functional groups of fulvic acids with copper, cadmium and zinc bivalent ions was investigated by potentiometry. The BEST7 software was employed to investigate the interactions of the functional groups.

Acid-base Properties of Modified Peat Fulvic Acid
Procedia Chemistry, 2014 AbstractThe Effect of Mechanochemical modification on the acid-base properties of fulvic acid peat has been studied. It is found that modifying reagent CS(NH2)2 increases the amount of aromatic fragments and has no effect on the depletion of functional groups.

Journal of Fish Biology, EarlyView.Abstract This study aimed to investigate how exposure to elevated water temperature and metal concentration jointly affect the physiology of Amazonian fish. Aboard a research vessel in the Amazon, we evaluated the effects of water temperature (river T°C at 31.5°C and a + 4°C increase to 35.5°C) and of 3‐h copper (Cu) exposure (up to 600 μg/L) in ...

GROWTH INCREMENT OF JUVENILE ACER PLATANOIDES L. AND SOIL ORGANIC MATTER AFTER APPLICATION OF ORGANIC FERTILIZERS [PDF]
Natural Resources and Sustainable Development, 2018 The effect of fertilization with organic fertilizers (Siapton and Biohumus) on the growth of Acer platanoides L. saplings was investigated. Four variants were used: Variant V1 - "Siapton" - 1 ml per sapling; variant V2 - "Siapton" 50 ml per sapling ...

Physiological Effects of Five Different Marine Natural Organic Matters (NOMs) and Three Different Metals (Cu, Pb, Zn) on Early Life Stages of the Blue Mussel (Mytilus galloprovincialis) [PDF]
, 2017 Metals are present in aquatic environments as a result of natural and anthropogenic inputs, and may induce toxicity to organisms. One of the main factors that influence this toxicity in fresh water is natural organic matter (NOM) but all NOMs are not the
