Abstract

The environmental microbiome plays an important role in various ecosystems around the world, influencing nutrient cycling, disease dynamics and ecosystem stability. This bibliometric analysis provides a comprehensive overview of the current state and future directions of environmental microbiome research from a global perspective from 2009–2024. Through systematic examination of Scopus publications, 2154 documents were found. The results show a significant increase in the number of publications since 2017 and a peak in 2024. The most cited document was "The hidden world within plants: Ecological and evolutionary considerations for defining functioning of microbial endophytes" with 1887 citations and “Structure and function of the global ocean microbiome” with 1843 citations. The most productive countries in environmental microbiome research are the United States (n = 748), China (n = 533), India (n = 308), Germany (n = 172) and the United Kingdom (n = 157). Microbiome, microbial community, microfolora, microbiota, microbiology, bacteria, and bacterium are the most popular topics that will continue to develop in the future. Although the United States has published the highest total number of papers, more recent studies have predominantly been published from China, indicating shift in the centre of study from the United States to China. Insights gained from this analysis contribute to a deeper understanding of the environmental microbiome research landscape, guiding future research priorities and collaborations in the field.

Abstract

This study aims to determine the structure of the gastropod community and the relationship between environmental parameters and gastropod abundance in the mangrove ecosystem of Kejawanan Beach. This study used a survey method using 10 x 10 m quadrant transects with 1 x 1 m subplots inside, with five points placed at each corner and in the center. The results of the study showed 12 families, including Potamididae, Littorinidae, Cerithiidae, Ellobiidae, Naticidae, Melongenidae, Coniidae, Nassariidae, Clavatulidae, Assimineidae, Ampullariidae, and Achatinidae. The total abundance of gastropods was 32.78 ind/m2. The diversity (H’) obtained falls into the moderate diversity category, with a value of 1.61. The evenness (E) obtained falls into the moderate evenness category and indicates a stable community, with a value of 0.62. The dominance (C) of gastropods indicates that no single species dominates across all research stations. The abundance of gastropods in the mangrove ecosystem of Kejawanan Beach shows a strong and positive relationship with environmental parameters such as silt fraction and salinity, and has a negative correlation with sand fraction and Dissolved Oxygen (DO).

Abstract

Endophytic fungi produce a wide array of secondary metabolites with diverse biological activities, including antibacterial, antifungal, insecticidal, and immunosuppressive effects. The increasing prevalence of infections caused by pathogenic bacteria, such as Escherichia coli, Bacillus subtilis, Salmonella typhi, Pseudomonas aeruginosa, Listeria monocytogenes, Bacillus pumilus, and Staphylococcus aureus, highlights the urgent need for novel antibacterial agents. This study aimed to determine the optimal concentration of ammonium sulfate for the isolation of endophytic fungus KT31 from Kappaphycus alvarezii based on its antibacterial activity. Fungal proteins were extracted using ammonium sulfate precipitation at varying saturation levels and subsequently tested for antibacterial activity against a panel of seven pathogenic bacterial strains. Crude protein extracts demonstrating promising activity were further purified using gel filtration chromatography with Sephadex G-50, followed by molecular weight determination usingDS-PAGE and protein quantification using a Bicinchoninic Acid (BCA) assay. The highest antibacterial activity was observed in the protein fraction precipitated at 80% ammonium sulfate saturation, exhibiting inhibition zones of up to 14 mm against E. coli and B. pumilus. A notable inhibition zone of 12 mm was observed for the most active chromatographic fraction. SDS-PAGE analysis revealed that the active protein had an estimated molecular weight of 11.27 kDa. These findings suggest that endophytic fungi, particularly the isolate KT31, represent a promising source of novel antibacterial peptides, warranting further investigation for therapeutic applications.
