Excised roots of barley (Hordeum vulgare, var. Campana) lost organic acids, amino acids, K(+), and Cl(-) within 15 minutes after initiation of anaerobic treatment or treatment with NaCN and 2,4-dinitrophenol. Initial loss of organic acids when roots were placed under N(2) is attributed to a decarboxylation reaction, possibly catalyzed by phosphoenolpyruvate carboxykinase. Organic and amino acid...

The exogenous delivery of organic molecules could have played an important role in the emergence of life on the early Earth. Carbonaceous chondrites are known to contain indigenous amino acids as well as various organic compounds and complex macromolecular materials, such as the so-called insoluble organic matter (IOM), but the origins of the organic matter are still subject to debate. We repor...

The efficiency of HZSM-5 Zeolite, tungestophosphoric acid (H3PW12O40) and tungestosililic acid (H4O40SiW12) were investigated in three-component, one-pot synthesis of coumarin dyes. These green and noncorrosive acids were highly efficient in synthesis of some coumarin dyes in excellent yield during concurrent formation of coumarin and benzimidazole or benzoxazole heterocycles (e.g. C. I. disper...

This study was conducted to evaluate the effects of dietary supplementation of protected organic acid blends including medium chain fatty acids and different nutrient density diets on growth performance, nutrient digestibility and faecal noxious gas content in growing pigs. A total of 80 crossed [(Landrace × Yorkshire) × Duroc] growing pigs with an initial body weight (BW) of 22.61 ± 2.32 kg we...

for determination the effect of lemon pulp levels and organic acid premix (globacid) on performance, carcass traits,immune system, biochemical parameters and intestinal morphology of broilers, 288 ross broilers were used in 3×2 factorial arrangement with three levels of lemon pulp (0, 1.5 and 3 percent) and two levels of globacid (0 and 0.1 percent) in a completely randomized design with six tr...

It has been shown in earlier reports1 that the organic phosphorus compounds of wheat bran which have been isolated after digesting the bran in 0.2 per cent hydrochloric acid differ in composition and properties from phytin or inosite hexaphosphate. It has been found that under these conditions several organic phosphoric acids are obtained. Of these we have isolated and identified t,wo; viz., in...

this study was conducted to study the effect of organic acids on the preservation of alfalfa nutritional value after harvesting. a split plot design with 4 treatments and 3 times was conducted in which organic acids were sprayed on the 30percent moisture content forage before baling. treatments were: 1) forage without additives as control, 2) pure propionic acid, 1percent, 3) acetic acid percen...

The terms acid neutralizing capacity (ANC) and alkalinity (Alk) are extensively employed in the characterization of natural waters, including soft circumneutral or acidic waters. However, in the presence of organic acids, ANC measurements are inconsistent with many conceptual definitions of ANC or Alk and do not provide an adequate characterization of the acid-base chemistry of water. Knowledge...

Objective:  In addition to the role of organic matter in plant nutrition, this material improves soil quality, physical structure, ventilation and water supply, and ease of penetration and expansion is rooted deep in the soil surface. Effects of organic matter due to climatic factors, soil characteristics may vary from region to region, resulting in organic materials management must be given to...
