Research ArticleOpen accessIn the keywordsBioaccumulation of Cr(III) ions by Blue-Green alga Spirulina sp. Part I. A Comparison with BiosorptionKatarzyna ChojnackaThe paper presents the results of studies on kinetics and equilibrium of bioaccumulation process of Cr(III) ions by blue-green alga Spirulina sp. Bioaccumulation was described as the process that consists of two stages, passive (identical with biosorption) and active (accumulation inside the cells). The passive stage (similarly as biosorption itself) was found to be quick process and the subsequent active … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,708 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCo-Digestion of Palm Oil Mill Effluent and Refined Glycerin Wash Water for Chemical Oxygen Demand Removal and Methane ProductionA. Sulaiman, M. R. Zakaria, M. A. Hassan et al.Problem statement: Refined Glycerin Wash Water (RGWW) from the oleochemical industry contains high Chemical Oxygen Demand (COD) and requires proper treatment before disposal. Unfortunately the wash water also contains high concentration of sodium chloride (NaCl) that could cause inhibition to the normal biological treatment process. However, there is feasibility of co-digesting the RGWW and Palm Oil Mill Effluent (POME) for … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,937 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New Method to Estimate Intrinsic Parameters in the Ping-pong Bisustrate Kinetic: Application to the Oxipolymerization of PhenolJosé L. Gómez, Antonio Bódalo, Elisa Gómez et al.A new method for determining the intrinsic parameters of reaction in processes involving a high initial rate has been developed. The usefulness of this alternative, which consists of determining several sets of apparent parameters at different times and then extrapolating these to time zero, is demonstrated proved by the linear dependence obtained between the apparent parameters and the reaction time. … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,534 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnaerobic Fermentation for Ceftriaxone Sodium Degradation in Excess Sludge: pH-Dependent Performance, Metabolite Formation, and Microbial Community DynamicsWeiwei Li, Hong Niu, Yonghui Zhang et al.The accumulation of ceftriaxone sodium (CTX), a third-generation cephalosporin antibiotic, in wastewater and sludge poses significant environmental and health risks, necessitating effective degradation strategies. This study investigated anaerobic fermentation of excess sludge (12,000-14,000 mg/L) spiked with 15 mg/L CTX under varying pH conditions (4, 7, 10, 12) to evaluate sludge reduction, metabolite formation, and microbial community dynamics. Results demonstrated that … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 31 Jul 2026 · 865 accessesView PDFCite
Review ArticleOpen accessIn the abstractMicrobial Degradation of Paracetamol in Pharmaceutical Wastewater: A ReviewYahya Seun Yisau, Naeif Hamoud Al-Makishah, Mohamed Abou El-Fetouh BarakatParacetamol (4′-hydroxyacetanilide or N-acetyl-p-aminophenol or Acetaminophen) is an analgesic and antipyretic over-the-counter commonly used drug. Paracetamol has been detected in, surface waters, wastewater, and drinking water globally because of its significant utilization and unregulated release into the surroundings which have been a great concern and require an urgent approach. Microbial degradation of paracetamol is considered a desirable choice because of … …American Journal of Environmental Sciences, Vol. 20, Issue 1 · 3 Aug 2024 · 6,925 accessesView PDFCite

Research ArticleOpen accessIn the abstractOptimization of Temperature and pH for Protease Production from Some Bacterial Isolates of Mangrove WatersFeskaharny Alamsjah, Yorasakhi Ananta, Anthoni AgustienProtease enzymes are widely used in biotechnology to produce amino acids and peptides from high molecular substrates, as well as in the leather industry for wastewater treatment, textiles, pharmaceuticals, cosmetics, leather processing, and poultry industry. Indonesia's demand for protease enzymes is increasing. This study aims to optimize the temperature and pH for the production of protease from certain bacterial isolates … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 11 Sep 2024 · 4,427 accessesView PDFCite
Research ArticleOpen accessIn the abstractWater Reuse in Industry: Necessities and PossibilitiesKaveh Ostad-Ali-Askari, Saeid EslamianTo begin with, lack of water, declining quality of it and environmental restrictions caused to increase requirements of reusing wastewaters extremely. By industrialization and reduction of pressure on water sources, using water in industry has adequate potential to reduce costs in saving water and treatment of wastewater. Wastewater can be recycled direct and indirect based on the type and quality. … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 23 Jan 2021 · 7,522 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Treated Wastewater in Terms of Environmental StandardsSona Pazdar, Saeid Eslamian, Hossein Gholami, Kaveh Ostad-Ali-AskariThe desired use of refined wastewater has not yet found its proper place in many countries, therefore, achieving a relative equilibrium in the field of urban wastewater evacuation and re-utilizing it is a fundamental principle. And this great matter is not possible except by developing a comprehensive refinery waste management system. The set of measures that have been taken so … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 4 · 27 Sep 2019 · 7,914 accessesView PDFCite
Review ArticleOpen accessIn the abstractChemical 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).
