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 · 1,413 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 · 5,002 accessesView PDF Cite

Research ArticleOpen accessEnhanced Amylase Activity by Modulating Abiotic Factors and Enzyme Stability in the Thermophilic Bacterial IsolatesAnthoni Agustien, Denny Bendrianis, Feskaharny Alamsyah et al.Amylase is one of the enzymes that is widely used in bioprocess technology, amylase from different microbial sources also varies in form, so it is suitable for its specific application. The purpose of this study was to determine the optimum temperature, pH, agitation, and stability of the amylase enzyme from two thermophilic bacterial isolates, TUA-07 and TUA-09. This study used … …OnLine Journal of Biological Sciences, Vol. 24, Issue 2 · 7 Feb 2024 · 5,500 accessesView PDF Cite
