Research ArticleOpen accessMolecular Identification and Antioxidant Profiling of Penicillium heteringtonii EUA-017 from Mangrove (Avicennia alba) in West Sumatra, IndonesiaAnthoni Agustien, Djong Hon Tjong, Yetria Rilda et al.Mangrove ecosystems harbor diverse endophytic fungi that produce bioactive secondary metabolites with potential antioxidant activities. This study aimed to identify an endophytic fungal isolate (EUA-017) from Avicennia alba mangroves in West Sumatra, Indonesia, and characterize its antioxidant metabolites. Molecular identification was performed using internal transcribed spacer (ITS) region sequencing. Secondary metabolites from ethyl acetate extracts were characterized using Fourier-transform infrared … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 25 Mar 2026 · 1,410 accessesView PDF Cite

Research ArticleOpen accessCultivation of Antioxidant-Producing Endophytic Fungus in Rhizophora apiculata Mangrove PlantsAnthoni Agustien, Putra Santoso, Siti Zaharani Zalamah et al.West Sumatra is known as one of the largest areas of mangrove forests in Indonesia, dominated by Rhizophora. Therefore, there will be huge opportunities to discover new types or strains of endophytes and antioxidant compounds, which play an important role in protecting cells caused by free radicals, preventing oxidation, and protecting the human body from ROS. This study aims to … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 4 Aug 2024 · 4,991 accessesView PDF Cite

Research ArticleOpen accessExploration and Characterization of Thermophilic Bacteria from the Kerinci-Jambi Geothermal Source for Alcohol ProductionAnthoni Agustien, Weni Cahyati, Yetria RildaAlcohol produced by thermophilic bacteria is renewable and a safe fuel because it is mainly based on microbial fermentation. This research needs to be done to find out the potential alcohol production of thermophilic bacteria because have many advantages such as degrading a much wider range of carbohydrates, the possibility of direct alcohol recovery from the fermentation broth, tolerance to … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 10 Feb 2024 · 5,199 accessesView PDF Cite
