Research ArticleOpen accessIn the abstractCoupling Analysis of Thermodynamic Equilibrium of Mass Transfer and Microbial Community Succession in Multiphase System of Dark Tea Solid-State FermentationZhanjun Liu, Jiawei Sun, Taotao Li et al.During the solid-state fermentation of dark tea, the limited material migration, the dynamic evolution of the thermodynamic equilibrium state, and the highly dynamic succession of the microbial community make it difficult to analyze the quality formation mechanism systematically. Traditional research has focused on microbial diversity or sensory quality analysis, lacking a systematic discussion on the regulatory effects of material migration … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 10 Aug 2026 · 1,004 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular 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 PDFCite
Review ArticleOpen accessIn the abstractEfficiency and Sustainability of Alternative Protein Sources for Livestock Production in Sub-Saharan Africa: A Systematic Review and Meta-AnalysisOlusegun Oyebade Ikusika, Bulo Luvuyo, Jaja Ishmeal FestusSub-Saharan Africa (SSA) faces growing challenges in sustainable livestock production due to high costs and limited availability of conventional protein sources such as soybean meal and fishmeal. This systematic review and meta-analysis evaluated the nutritional efficiency and sustainability of locally available alternative protein sources for livestock feed in SSA. Following PRISMA guidelines, systematic searches were conducted across five databases (PubMed, … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 4 · 19 Feb 2026 · 1,844 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Fertilization Frequency and Amount on the Chemometric Characteristics, Physiology, and Yield of Tomato Under Substrate CultivationEnling Ji, Qianqian Di, Qingjie Du et al.This study examined the effects of fertilization frequency and quantity on growth, yield, and quality of tomatoes under substrate cultivation. A factorial experiment evaluated two fertilization frequencies (every 5 or 10 days) and three fertilization levels (15.69, 31.38, or 62.76 kg·ha⁻¹), along with an unfertilized control. Plants were assessed for growth and development, photosynthetic pigment content, gas exchange parameters, nutrient … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 16 Feb 2026 · 1,715 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Impact of Carbon Tax on Agricultural Output, Employment, and Rural Income in Indonesia: Insights from an Energy Input-Output ModelSyahrituah Siregar, Luthfy Fatah, M. Handry Imansyah, SunardiThe agricultural sector in Indonesia is crucial for the national economy, contributing significantly to Gross Domestic Product (GDP) and sustaining the livelihoods of millions in rural areas. In light of increasing global environmental concerns, this study examines the potential impacts of a proposed carbon tax on agricultural production, employment, and rural household income in Indonesia. Utilizing the Miyazawa energy input-output … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 12 Jun 2025 · 3,393 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn vitro Ruminal Cumulative Gas and Methane Production, Enzyme Activity, Fermentation Profile and Nutrient Digestibility on Feed Supplemented with Organic SeleniumMoh. Sofi’ul Anam, Andriyani Astuti, Budi Prasetyo Widyobroto et al.Methane (CH4) emissions are indeed a global environmental concern and ruminants are a significant source of these emissions; however, there is limited understanding regarding the contribution of organic Selenium (Se) in mitigating CH4 emissions. Hence, this study investigated the impact of supplementing organic Se from Selenomethionine (Se-Met) on the in vitro ruminal cumulative gas and CH4 production, fermentation profile, enzyme … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 4 · 26 Oct 2023 · 5,215 accessesView PDFCite
