Unveiling the Bacteriophage Reservoir of the Ganga River: Ecological Roles, Environmental Drivers, and Biotechnological Potential

What is it about?

The review article “Unveiling the Bacteriophage Reservoir of the Ganga River: Ecological Roles, Environmental Drivers, and Biotechnological Potential” explores the diversity, ecological significance, and practical applications of bacteriophages (viruses that infect bacteria) in the Ganga River ecosystem. The Ganga has long been known for its remarkable self-purifying ability, and this review examines the possibility that naturally occurring bacteriophages contribute to this phenomenon by regulating bacterial populations and maintaining microbial balance. However, increasing pollution from untreated sewage, industrial effluents, agricultural runoff, and religious activities has significantly altered the river's microbial ecosystem, making it essential to understand how bacteriophages respond to these environmental changes. The article reviews the distribution of bacteriophages throughout different stretches of the Ganga River and discusses how environmental factors such as pH, temperature, dissolved oxygen, nutrient availability, and pollution influence phage diversity and activity. It highlights several important bacteriophage families, including Myoviridae, Siphoviridae, Podoviridae, and Microviridae, which interact with diverse bacterial hosts and play critical roles in controlling bacterial abundance, recycling nutrients, and maintaining ecological stability. By lysing bacterial cells, these viruses help regulate microbial communities and support the natural functioning of aquatic ecosystems. Beyond their ecological importance, the review emphasizes the growing biotechnological potential of bacteriophages. It discusses their applications in phage therapy as an alternative to antibiotics, particularly against antimicrobial-resistant bacteria, as well as their use in wastewater treatment, environmental monitoring, bio-surveillance, and bioremediation. The authors also identify major research gaps, including limited virome studies, insufficient genome-level characterization, and the need for long-term monitoring across the entire Ganga River. Overall, the review concludes that understanding the bacteriophage reservoir of the Ganga will not only improve our knowledge of river ecology but also contribute to sustainable environmental management, public health protection, and the development of innovative antimicrobial strategies for the future.
