Research ArticleOpen accessIn the keywordsModeling Water Quality in RiversLiren Yu, N. N.B. SalvadorThis study reports a PC software, used in a Windows-based environment, which was developed based on the first order reaction of Biological Oxygen Demand (BOD) and a modified Streeter and Phelps equation, in order to simulate and determine the variations of Dissolved Oxygen (DO) and of the BOD along with the studied river reaches. The software considers many impacts of … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,858 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Pseudomonas aeruginosa Infecting Bacteriophages from Swiftlet House Pond Water and Sewage in South Kalimantan, IndonesiaSiti Gusti Ningrum, Dyah Widhowati, Titin Yulinery et al.Pseudomonas aeruginosa is an opportunistic bacterium that may occur in animal-production environments and contribute to microbial contamination of animal-derived products. However, information on P. aeruginosa-infecting bacteriophages in artificial swiftlet-house environments remains limited. This study aimed to isolate and evaluate P. aeruginosa-infecting bacteriophages from the swiftlet-house environment in South Kalimantan, Indonesia. A total of 75 samples involving pond waters (n = … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 3 · 26 Oct 2026 · 55 accessesView PDFCite

Research ArticleOpen accessIn the abstractFabrication of Polysaccharides from a Fermented Tea and Their Antioxidant and Hypoglycemic ViabilityJun Li, Lingxian Tong, Bing Li et al.The hypoglycemic effects of tea have been extensively studied, with fermented tea demonstrating notable efficacy owing to its distinct processing methods. This study involved the extraction of tea polysaccharides from Wuniuzao Black Tea (WTP) using a water extraction and ethanol precipitation method. WTP-1 and WTP-2 were obtained by separation and purification using DEAE-52 cellulose columns. Antioxidant activity was evaluated utilizing … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 30 Jul 2026 · 655 accessesView PDFCite
Research ArticleOpen accessIn the abstractSwiftlet Bacteriophages Concerning Diversity and Biological Features in South Kalimantan, IndonesiaSiti Gusti Ningrum, Hana Cipka Pramuda Wardhani, Intan Permatasari HermawanWe aimed to isolate and characterize bacteriophages infecting Nitrobacter spp. from swiftlet house environments and to evaluate their biological properties as potential biocontrol agents to mitigate nitrate accumulation in edible bird’s nest (EBN) production. Environmental samples were collected from multiple swiftlet houses in South Kalimantan, Indonesia. Samples were enriched with Nitrobacter cultures, and bacteriophages were detected using spot assays followed … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 1 · 17 Apr 2026 · 1,759 accessesView PDFCite
Research ArticleOpen accessIn the abstractScreening of Bioactive Constituents from the Aerial Parts of Dictamnus dasycarpus Turcz. With Antioxidant, Immunoenhancing, and Anticoagulant PotentialJiaqi Sun, Shiyu Ji et al.The cultivation of Dictamnus dasycarpus Turcz (DdT) is expensive and difficulty associated with growing, making its root bark the only commonly used medicinal part, while other parts are discarded. Therefore, in order to improve the limited utilization of resources, the new medicinal parts were screened from polysaccharide-rich aqueous extracts. The samples were the purified polysaccharides from the aerial part on … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 9 Oct 2025 · 2,018 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Study on the Microbial Community Structure of the Sediment of Pi River under the Different pH in WinterCairui Yu, Dongmei Shen, Wanfeng Wang et al.In order to solve the poor self-purification ability of low temperature water in winter, the microbial community structure in the sediment of Pi River water (located in West Anhui) was investigated experimentally in this study. Firstly, the sediment was sampled in the lower reaches of Pi River and prepared with the different pH (5.0, 5.5, 7.0 and 8.5); secondly, the … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 15 Mar 2021 · 6,122 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 · 7,908 accessesView PDFCite
Literature ReviewOpen accessIn the abstractReview of Blue-Green Infrastructure in Some Selected CountriesTariku Neme Afata, Seyoum Derib, Reda NemoBlue-Green Infrastructures (BGI) integrate solutions implemented to enhance water management and landscape values for more climate-resilient and livable cities.
