Research ArticleOpen accessIn the keywordsModelisation of Nitrification under Inhibited Environment by Moving Bed Bio-Film Reactor TechniquePham Thi Hong Duc, Le Van Cat, Jean-Luc VaselProblem statement: Nitrification by Moving Bed Biofilm Reactor (MBBR) involves physical, chemical and biological processes to remove toxic ammonia for aquaculture that are governed by a variety of parameters, like substrate and dissolved oxygen concentrations, organic matters, temperature, pH, alkalinity and turbulence level, which impact negatively or positively on nitrification kinetics. Approach: The situation becomes more serious as the reaction … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 6,946 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptimization of Ultrasonic-Assisted Total Flavonoids Extraction from Flower of Albizia Julibrissin Durazz. by Response Surface Methodology for Characterization of Chemical Profile and Evaluation of Antioxidant and Tyrosinase Inhibitory ActivitiesYijie Cheng, Yuwen Zhang, Hanzhang Sun et al.To investigate the flavonoids in flower of Albizia julibrissin (‘He Huan Hua’ in Chinese), the ultrasonic-assisted extraction of total flavonoids from ‘He Huan Hua’ was optimized by response surface methodology and the chemical profile was characterized by HPLC- QTOF-MS/MS. What’s more, the antioxidant and tyrosinase inhibitory activities of ‘He Huan Hua’ were also evaluated in this study. The extraction time, … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 1 · 14 Mar 2022 · 6,733 accessesView PDF Cite

Research ArticleOpen accessIn the abstractExtraction Optimization of Essential Oil from Medicago hispida and Preliminary Inhibitory Mechanism Against Escherichia coliXiulan Chu, Qianfeng Chen, Tong Wang et al.In this study, the extraction optimization, characterization, antioxidant evaluation and preliminary inhibitory mechanism against Escherichia coli of the essential oil from dried Medicago hispida (EOMH) were explored to uncover the pending questions that had been raised in our previous work and to enlarge the industrial potential of EOMH production. The optimal parameters for EOMH extraction were: Extraction time of 7 … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 4 · 20 Nov 2021 · 5,789 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Steam Conditioning and Extrusion Temperature on Some Anti-nutritional Factors of Soyabean (Glycine max) for Pet Food ApplicationsB. Purushotham, P.M. Radhakrishna, B.S. SherigaraExtrusion processing of vegetable ingredients such as soyabean (Glycine max) characteristically depends on associating process conditions that influence the product qualities. The process parameters were optimized for extrusion of steam-conditioned material in order to obtain the maximum nutritive value by inactivating the anti-nutritional factors such as urease, trypsin inhibitors and lipase. The processing conditions such as moisture content, temperature and … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 1 · 31 Jul 2007 · 9,021 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInterleukin 10 Induces the Maturation of Putative Tolerogenic Monocyte-derived Dendritic Cells as Revealed by GeneArray AnalysisMarianne A. Jakobsen, Bjarne K. MØller, Klaus Rieneck et al.IL-10 is a multifunctional cytokine with known inhibitory effect on DC maturation. In the present study, we show that the presence of IL-10 during the first 6 days of maturation of Mo-DC has severe effects on the phenotype with IL-10 treated Mo-DC retaining a high expression of factors involved in antigen uptake and having low expression of costimulatory factors and … …American Journal of Immunology, Vol. 1, Issue 4 · 31 Dec 2005 · 6,621 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPHENOTYPING, VIRULENCE CHARACTERISTICS OF AEROMONAS SPECIES AND THE EFFECTS OF ESSENTIAL PLANT OILS AS ANTIMICROBIAL AGENTS AGAINST PATHOGENIC ISOLATES FROM DIFFERENT SOURCESAhmed M.A. Mansour, Hoda M. Zaki, Nibal A. Hassan, Nihad A.M. El-NasharAeromonas species are increasingly recognized as enteric pathogens. Faecal samples from 20 cow, 45 sheep; 60 goat and 60 camels were examined for the presence of Aeromonas species, which was also sought in the available drinking water (55 well water and 52 drinking chlorinated tap water were also examined). Aeromonas species was isolated more frequently from goats (21.7%) than from … …American Journal of Infectious Diseases, Vol. 10, Issue 1 · 18 Jan 2014 · 8,020 accessesView PDF Cite
