Research ArticleOpen accessEvery word in the titleExposure to Mercury at Trace Concentrations Leads to Collapse of the Hepato-Nephrocitic System in Two Neotropical Species of BumblebeeFelipe Lissoni de Andrade Nogueira, Paulo José Bálsamo, Monica Jones Costa, Fábio Camargo AbdallaThis research aimed to investigate the effects of exposure to safe concentrations of mercury on the morpho-physiology of cells of the hepato-nephrocitic system of two species of neotropical bees. Workers of the neotropical bumblebee species Bombus morio and B. atratus were exposed to 0.2 ppb mercury for 48 h by ingestion. Bioassays were performed according some direction of OECD (2017) … …American Journal of Agricultural and Biological Sciences, Vol. 14, Issue 1 · 14 Dec 2018 · 8,617 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImplementation of Species-Transport Model in Numerical Simulation to Predict the Performance of Downdraft Gasifier with Biomass BlendsMurugan P. C., G. Arun Prasad, S. Joseph SekharThe demand for energy from biomass gasification is increasing due to the depletion of fossil fuels and serious environmental issues. Due to this, usage of individual biomass in a gasifier is not sufficient to meet the demand in rural areas. However, an enormous study have been reported on the gasifier with single biomass as working fuel. In addition, only a … …Energy Research Journal, Vol. 10, Issue 1 · 11 Sep 2019 · 7,639 accessesView PDFCite
Research ArticleOpen accessIn the keywordsModeling Growth of Microalgae Dunaliella Salina under Different Nutritional ConditionsSergio Santos Jesus, Rubens Maciel FilhoProblem statement: The aim of this study was to find the empirical model that describes the growth kinetics of Dunaliella salina, with low production cost and to estimate parameters of this model. Approach: In this study the strain of D. salina UTEX 200 was cultivated in seawater (0.5 M NaCl) at room temperature with agitation of 150 rpm and luminous … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 4 · 31 Dec 2010 · 9,014 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTrace Metal Mercury Levels in Residential Homes in KuwaitL. AL-Awadi, A. R. Khan, R. Al-KandariKuwait is an oil rich state on the northeastern corner of Arabian Peninsula and has faced the unprecedented man made environmental disaster in early 1991 of igniting over 600 oil wells those continually burnt for a period of over six months. The use of crude and heavy fuel oil in the power generating facilities has aggravated the pollution due to … …American Journal of Environmental Sciences, Vol. 4, Issue 1 · 29 Feb 2008 · 6,827 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioethanol Production from Graminoid Weeds in Bayero University Kano: A Potential Feedstock for Future Sustainable Aviation Fuel ApplicationsAdam Salihu Kila, Sa’idu Hassan Musa, Umar Aliyu Ahmed et al.This study evaluates the potential of selected graminoid weeds from Bayero University, Kano (BUK), Nigeria, as feedstock for bioethanol production. Ten (10) abundant weed species, including Cenchrus species, Cynodon dactylon, and Setaria barbata, were subjected to physicochemical pretreatment (ultrasonication, hydrothermal treatment, and enzymatic hydrolysis) followed by fermentation using Bacillus subtilis, Saccharomyces cerevisiae, and their co-culture. Pretreatment significantly enhanced reducing sugar … …Energy Research Journal, Vol. 15, Issue 1 · 15 Jul 2026 · 1,170 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Metal Ions on The Functional Properties of Taro Protein IsolateYouru Huang, Yingtong Li, Zheng Zhang, Maoqiang ZhengThis study investigated the effects of metal ion species and concentrations on the functional properties of taro protein isolate (TPI), extracted from Colocasia esculenta corms. The results demonstrated that metal salt solutions could modulate the unfolding and aggregation of TPI, thereby altering its protein-protein and protein-water interactions and significantly affecting the functional properties. When monovalent cation concentration [M+] was less … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 6 Jan 2026 · 2,012 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of the Saccharomyces Boulardii Supplement in Combined Feed on the Health, Growth, and Fecal Microbiota of Growing CalvesDulat Zhalelov, Serkan Ozkaya, Mehmet Gündoğdu et al.The aim of this study was to study the effect of a specific strain of yeast, Saccharomyces cerevisiae boulardii T8-3C (SCB), on the growth, health, and bacterial profile of calves' feces. A total of 12 animals were included in the experiment on a commercial calf farm for a total of 90 days. The calves were fed hay and alfalfa twice … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 27 Nov 2025 · 2,309 accessesView PDFCite
Research ArticleOpen accessIn the abstractCadmium Stress Responses in Medicinal and Oilseed Plants: Safflower as a Promising Candidate for Soil Cadmium RemediationChristos Kikis, Giorgos Thalassinos, Vasileios AntoniadisThis study investigated the growth responses of five economically important plants—chamomile (Matricaria recutita), oregano (Origanum vulgare), safflower (Carthamus tinctorius), sage (Salvia officinalis), and wormwood (Artemisia absinthium) exposed to increasing Cd levels. Over 60 days, plants were subjected to Cd concentrations of 0, 1, 2, 3, and 4 mg per pot. Growth parameters and Cd accumulation were then assessed. At the … …American Journal of Agricultural and Biological Sciences, Vol. 20, Issue 1 · 13 Nov 2025 · 3,410 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Fructan Content from Stem Juices of Different Varieties of Agave Atrovirens, Traditionally Used for the Production of Pulque. Production of a Sweetening Syrup by Chemical and Enzymatic ProcessingKaren Gott-Bravo, Arnulfo Pluma-Pluma, Victor Eric López-López et al.Agave atrovirens, the hardiest species of Agave in Mexico, thrives in tough, infertile soils and extreme temperatures across a wide range of altitudes, particularly in impoverished rural areas of Central and Northern Mexico. Its potential for agroindustrial use could offer a pathway to social and economic prosperity for many communities. Traditionally, A. atrovirens is tapped for its sap, known as … …American Journal of Agricultural and Biological Sciences, Vol. 19, Issue 1 · 4 Mar 2025 · 7,670 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation and Identification of Bacteria Leading to Microbial Spoilage of Sweet Potato and Screening for Antistaling Agents Running HeadDaoqi Liu, Huili Liu, Yuanyuan Dang et al.To develop natural preservatives tailored for sweet potatoes, the control effect of essential oils on the spoilage microorganisms of sweet potatoes is uncertain. Therefore, we first isolated and identified the dominant spoilage bacteria from spoiled sweet potatoes. Micrococcus aloeverae, Priestia aryabhattai, and Glutamicibacter arilaitensis were identified through screening, morphological observation, gram staining, and 16S rDNA assays. Subsequently, five plant essential … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 1 · 26 Apr 2024 · 5,221 accessesView PDFCite
