The Effects of Topically Applied Citric Acid on Periodontally Diseased Root Surfaces
… accelerated reattachment and cementogenesis when citric acid was applied to surgically created root surface defects. There are apparently no reports in the literature regarding the effects of citric acid on periodontally diseased root surfaces. This study was designed to determine the effects of …

Phytoextraction of Lead from Contaminated Urban Soils by Panicum virgatum Enhanced with Phytohormone, EDTA, Benomyl, and Citric Acid Application
… the soil-fungicide benomyl, chelates (EDTA and citric acid), and phytohormones for phytoextraction of Pb from contaminated urban soils in Atlanta, GA. EDTA is often regarded as the most effective chelate, but has potential problems associated with its use due to long persistence time in soil and …

Induced Phytoextraction of Lead from Contaminated Soils by Panicum virgatum, Enhanced with EDTA, Citric Acid, Benomyl, Propiconazole and Nitric Oxide
… switchgrass tissues. Ethylenediamintetraacetic acid (EDTA) is regarded as a highly effective chelate, though its long soil persistence leads to potential concerns about Pb mobilization into groundwater. Citric acid has been proposed and found success as an alternative chelate that has a …

Effect of feeding fumaric or citric acid on weanling pig performance and selected intestinal digesta measurements at varying times postweaning
… a possible mode of action of dietary organic acids in weanling pigs (n=536). The effect of feeding 1.5% fumaric or citric acid on growth performance, intestinal digesta pH, chloride ion concentration (Cl-), VFA profile and microflora populations was studied. In study 1, feeding citric acid …

A Specialized Citric Acid Cycle Requiring Succinyl-Coenzyme A (CoA):Acetate CoA-Transferase (AarC) Confers Acetic Acid Resistance on the Acidophile Acetobacter aceti
The characteristic ability of acetic acid bacteria to aerobically oxidize ethanol to acetic acid has been harnessed for millennia to produce vinegar. Acetic acid permeates cell membranes at low pH and generally inhibits bacterial growth at low millimolar concentrations. The strains used for vinegar …

Development of deflector flat spray nozzle with mixed of water and organic citric acid for emissions trap and cooling in the kitchen hood ventilation system
… The other function is to introduce organic citric acid as an agent to absorb gas emitted during cooking, besides looking at the effect of nozzle design in limiting gas emission and reducing kitchen hood temperature during cooking. Several methods were used in this study, such as the …

Degradação microbiana de ácido cítrico em solo contaminado por chumbo
… on the ability of soil microbes to decompose the citric acid used as complexing metal ions in the soil. The global activity microbial was determined by the ability of C-CO₂ soil in 0.1 M NaOH solution under a continuous flow system of air. We used a completely randomized design with three …

Further Evaluation of the Available Phosphorus Requirement of Laying Hens and Methods for Improving the Availability of Phosphorus in Feedstuffs for Poultry
… the efficacy of phytase for increasing amino acid utilization of three different laying hen diets. The results indicated that 300 units phytase/kg did not improve amino acid digestibility in laying hen diets containing corn, soybean meal, meat and bone meal and wheat middlings. Chicks were …

Zitronensäureether als Liganden für die zuverlässige Funktionalisierung von magnetischen Nanopartikeln
Two long-chain citric acid ethers have been synthesized. These ligands are used for the functionalization of magnetite- and alloyed iron/cobalt nanoparticles. These new particles are analysed by a combination of AGM, XRD, TEM, determination of the iron content, IR- and 1H-NMR-spectroscopy. It is …

Effects of Enhancement Solution pH on Fresh and Cooked Color of Dark-Cutting Beef
… strip loins were used to test the effects of citric acid-enhancement pH on visual and instrumental color of fresh and cooked steaks. Dark cutting and normal pH strip loin were injected to 111% of raw product weight with pH 3.5, 4.0, 4.5, or 5.0 solutions by mixing citric acid in either 0.05% …

DYNAMIC SURFACES FOR URINARY CATHETERS: THE EFFECT OF POLY (GLYCEROL SEBACATE CITRATE) COMPOSITION ON DEGRADATION, ENCRUSTATION RESISTANCE AND BACTERIAL RESPONSE
… citrate (PGSC) produced in-house. The effects of citric acid concentration on the degradation characteristics, mechanical behaviour, hydrophilicity and encrustation resistance of bulk samples were investigated and the feasibility of coating a silicone catheter material with PGSC using oxygen …

New Attachment of Connective Tissues to Human Teeth Involved in Chronic Periodontal Disease : A Histologic Study
… in humans. Garrett (1978) has shown that citric acid, after application to root planed tooth surfaces, produces a four micron wide demineralized zone which is characterized by exposed collagen fibers. It is impossible that this demineraIization may lead to new attachment by enhancing …

Investigating a novel in vitro embryo culture system – The Walking Egg Affordable Assisted Reproductive Technology
… was carried out. The utilization of citric acid and bicarbonate of soda for carbon dioxide production, which subsequently facilitate setting of pH values, was tested by injecting increasing citric acid volumes (1.2 ml – 3.0 ml in 0.2 ml increments) into set volumes of bicarbonate of …

Photocatalytic Degradation of Perfluorooctanoic Acid in Water by Free and Immobilised ZnO, g-C3N4 and Their Composite under UV and Visible Light Irradiation
Perfluorooctanoic acid (PFOA) is among perfluoroalkyl and polyfluoroalkyl substances (PFAS) that is widely detected in the environment. ZnO and graphitic carbon nitride are among the most economical semiconductors which have not been widely used for PFOA decomposition. Therefore, ZnO could be an …
