Research ArticleOpen accessIn Vitro and in Silico Evaluation of Bioactive Compounds from Usnea longissima Ach. as Antimicrobial AgentsOky Kusuma Atni, Erman Munir, Nursahara Pasaribu et al.Lichens, formed from symbiotic association between of fungi with phototrophic organisms, generate a variety of bioactive chemicals having medicinal potential. This research aimed to examine the antibacterial characteristics of Usnea longissima Ach. using both in vitro and in silico methodologies. The effectiveness of lichen methanol extracts against different diseases was evaluated using the disc diffusion technique. Pathogens included gram-positive, gram-negative, … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 10 Feb 2026 · 1,721 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 accessThe Diversity of Fungi in Landfill and their Potential to Degrade PlasticErman Munir, Yitro Pasaribu, Syahira Mubtasima, Ahmad Faisal NasutionPlastic has been known as a recalcitrant material and is very difficult to degrade in nature, resulting in its accumulation and threatening the environment if it is not managed properly. Studies on the degradation of plastics have been obtaining much attention recently. This study aimed to determine the diversity of fungi isolated from plastic wastes in landfills and to identify … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 1 Mar 2024 · 6,693 accessesView PDF Cite

Research ArticleOpen accessDiversity 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 PDF Cite

Research ArticleOpen accessIsolation and Characterization of Phosphate Solubilizing Activity of Endophytic Fungi from Zingiberaceous SpeciesErman Munir, Yurnaliza, Anisa Lutfia, Adrian HartantoPhosphorus (P), which is one of the less available soil macronutrients, is important for plant growth and metabolism. A promising strategy to increase the P uptake by plants is by introducing Phosphate-Solubilizing Microorganisms (PSM) into the P-deficient regions, to convert P into soluble forms through organic acids secreted by the PSMs. The aim of this study was to characterize the … …OnLine Journal of Biological Sciences, Vol. 22, Issue 1 · 27 Mar 2022 · 6,651 accessesView PDF Cite

Research ArticleOpen accessExamination of Chitinolytic Bacteria in Alginate-Chitosan Encapsulation on Chili Seed Against Damping off Caused by Fusarium oxysporumDwi Suryanto, Affan Indarwan, Erman MunirOne alternative in biological control of plant pathogenic fungi is to provide biological agent inoculant in coated seed. This study was to evaluate potential control and viability of two chitinolytic bacteria, Enterobacter sp. BK15 and Bacillus sp. BK17 of alginate-chitosan encapsulation coated on chili seed against damping off caused by Fusarium oxysporum. Chili seed beads were stored at refrigerator and … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 4 · 5 Dec 2012 · 7,913 accessesView PDF Cite
