Research ArticleOpen accessPhrase in the titleBiodegradation of Phenolic Compounds in Creosote Treated Wood Waste by a Composting Microbial Culture Augmented with the Fungus Thermoascus aurantiacusAbdel E. Ghaly, Bopeng Zhang, Deepika DaveProblem statement: Creosote is used as a wood preservative and water proof agent in railway sleepers, utility poles, buildings foundations and fences and garden furniture. It is a mixture of over 300 hydrocarbons which include 75% polycyclic aromatic hydrocarbons, 2-17% phenolic compounds and 10-18% heterocyclic organic compounds. Exposure to creosote may result in several health problems including damage to kidney, … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 2 · 26 Aug 2011 · 9,446 accessesView PDF Cite

Review ArticleOpen accessPhrase in the titleChemical Coagulation/Flocculation Processes for Removal of Phenolic Compounds from Olive Mill Wastewater: A Comprehensive ReviewMounia Achak, Fatima Elayadi, Wafaa BoumyaOlive oil extraction processes generate three phases: Olive oil, solid residue (pomace) and aqueous liquor Olive Mill Wastewater (OMW). OMW causes serious environmental deteriorations such as coloring of natural waters, alteration of soil quality, phytotoxicity and odor nuisance. The direct discharge of this effluent into the soil bring various negative effects on the environment, due to its high load of … …American Journal of Applied Sciences, Vol. 16, Issue 3 · 30 Mar 2019 · 10,494 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleProfiling of Phenolic Compounds of Somatic and Reproductive Tissues of Agave Durangensis Gentry (Agavaceae)Norma Almaraz-Abarca, Elí Amanda Delgado-Alvarado, Vicente Hernández-Vargas et al.Problem statement: In Durango, Mexico, mescal is elaborated from wild plants of Agave durangensis. This species shows a high morphological variability within and among populations, what makes its taxonomic delimitation a hard task. Approach: In this study the pollen and foliar phenolic compositions of Agave durangensis were analyzed by HPLC/DAD with the aim of determining the significance of phenol profiles … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,740 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsEffect of Water Bath Heating on Tannin Content and Quality Improvement Potential of Gambier (Uncaria gambir Roxb.)Daimon Syukri, Bastian Nova, Rina Yenrina et al.Gambir (Uncaria gambir Roxb.) is a source of natural phenolic compounds rich in catechins and tannins and has potential as a sustainable industrial raw material. During heating, phenolic compounds may undergo structural changes, including possible oxidation and polymerization, which can affect gambier quality beyond its catechin content. This study evaluated the effect of indirect heating duration using a water bath … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 23 Sep 2026 · 704 accessesView PDF Cite
