Research ArticleOpen accessIn the keywordsIsolation and Characterization of Superior Symbiotic Bacterial Isolates from the Oenggae Sea with Potential as AntibacterialLukas Pardosi, Adelya Irawan Manalu, Charles Venirius LisnahanSponges are one of the marine biota that have a symbiotic relationship with bacteria which can produce secondary metabolites as antimicrobials. The main aim of this research was to isolate and identify bacteria that had potential as antibacterials against multi-drug resistant test bacteria. The sponsor samples used in this research were Stylissa massa, Salvador Dali, and Angelas sp. The methods … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 26 Mar 2024 · 5,053 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPlant Growth Promoting Activity of Actinomycetes Isolated from Soybean RhizosphereAris Tri Wahyudi, Jepri Agung Priyanto, Resti Afrista et al.Plant Growth Promoting Rhizobacteria (PGPR) is considered as the biological agent for improving plant growth. One Group of PGPR that have an important role in growth promoting of plant is Actinomycetes. The objective of this study was to isolate and screen Actinomycetes isolated from soybean rhizosphere as growth promoter of soybean in vitro. Fifty-three Actinomycetes isolates have successfully been isolated … …OnLine Journal of Biological Sciences, Vol. 19, Issue 1 · 5 Jan 2019 · 14,604 accessesView PDFCite
Research ArticleOpen accessIn the keywordsScreening and Characterization of Sponge-Associated Bacteria Producing Bioactive Compounds Anti-Vibrio sp.Aris Tri Wahyudi, Jepri Agung Priyanto, Wenang Maharsiwi, Rika Indri AstutiIn Indonesia, vibriosis is the main disease in shrimp. This disease is caused by Vibrio sp that may decrease the productivity of shrimp cultivation. Thus, exploration for new bioactive compounds as vibriosis biocontrol agent is necessary. Marine sponge-associated bacteria is one of many sources for bioactive compounds. The aim of this study was to screen marine sponge-associated bacteria producing anti-Vibrio … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 3 · 5 Oct 2018 · 10,357 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIDENTIFICATION, MOLECULAR CHARACTERIZATION AND EVALUATION OF SOME RUMINAL BACTERIA THAT CATALYZE AND DEGRADE PLANT CELLULOSIC MATERIALSAhmed A. Mansour, T. S. El-Tayeb, N. E. El-BordenyIn the last few years there was a growing economic awareness about plant wastes and use it in compost production or in feeding of farm animals, some of these wastes are useless and cause a lot of problems in Egyptian environment. This study was designed to isolate, identify and evaluate some ruminal bacterial isolates to facilitate the in vitro degradation … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 10 Dec 2013 · 7,134 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBioremediation Potential of Heavy Metal-Resistant Bacteria in Koto Panjang Reservoir, Riau, IndonesiaIrda Sayuti, Darmadi, Adrian Hartanto et al.Koto Panjang Reservoir serves as a vital water resource supporting the social well-being of the local community in the Riau Province. The flow of the Kampar River, acting as the riverine zone and water inlet to the reservoir, provides environmental support for the construction of hydroelectric power plants (PLTA) and the aquaculture practice of Floating Net Cages (FNC). Over the … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 10 Feb 2025 · 4,534 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDiversity of Culturable Halophilic Archaea and Bacteria from Chott Tinsilt and El Malah Salt-Lake in AlgeriaAkmoussi-Toumi Siham, Khemili-Talbi Souad, Kebbouche-Gana Salima et al.At the limits of life, hyper-saline aquatic ecosystems; Chott and Sebkha are a model of choice of extreme environments, housing a halophilic microflora that had to adapt to these conditions. In Algeria, these ecosystems are poorly studied. However, our study was carried out on the waters of Chott Tinsilt and Sebkha El Malah. The study of this microflora revealed the … …Current Research in Bioinformatics, Vol. 8, Issue 1 · 28 Feb 2020 · 7,536 accessesView PDFCite
Research ArticleOpen accessIn the abstractMechanism of Mulberry's Effect on Intestinal Flora and MotilityHuizhen Zhao, Shijing Xie, Yuwen Li et al.Studies have indicated that mulberry consumption promotes intestinal motility and alleviates constipation, but the specific mechanism remains unclear. This study adopted a constipation mouse model to empirically analyze the effects of mulberry on intestinal motility, gut microbiota composition, and neurotransmitter levels, aiming to elucidate its mechanism of action. Key findings are as follows: 1) Compared with the model group, the … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 2 Jul 2026 · 1,189 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization and Molecular Identification of Protease-Producing Thermophilic Bacterial Isolate TUA-26Anthoni Agustien, Mufidhatul Muqarramah, Feskaharny AlamsjahProtease enzymes are used as biocatalysts that can accelerate a reaction. Thermostable enzymes produced by thermophilic bacteria are needed in the industrial field because of their ability to withstand high temperatures. The thermophilic bacterial isolate TUA-26 that produces protease was to analyze the optimum conditions of temperature, pH, agitation, trace elements, carbon sources, and nitrogen sources; the stability of protease … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 6 Apr 2024 · 4,935 accessesView PDFCite
Research ArticleOpen accessIn the abstractDiversity of Cellulolytic Bacteria from the Digestive Tract of Oryctes rhinoceros LarvaeAhmad Faisal Nasution, Erman Munir, Dwi Suryanto et al.Lignocellulose is a ubiquitous biopolymer that, once degraded into monomeric products, could be used to produce a wide range of products. Bioconversion using indigenous microbes could be a solution to the large array of cellulosic waste and it could be sourced from exotic organisms such as Asiatic rhinoceros beetle (Oryctes rhinoceros L). This study aimed to cellulolytic bacteria from the … …OnLine Journal of Biological Sciences, Vol. 23, Issue 4 · 2 Sep 2023 · 4,972 accessesView PDFCite
Research ArticleOpen accessIn the abstractDiversity and Resistance of Bacteria Isolated from a Neonatal Intensive Care Unit (NICU) Surfaces and the Hands of Nurses in Jeddah-Saudi ArabiaRoqaiah M. Al-Jabri, Ahmed M. Al-Hejin, Rukaia Gashgari et al.Healthcare-Associated Infections (HAIs) are a serious problem for neonates when admitted to NICUs. The healthcare environment and healthcare workers' hands may be a source of transmission.
