Microbial symbiosis is a research area that focuses on the interactions between different microorganisms living in close association with each other. These interactions can be beneficial, detrimental, or neutral, and can occur between different species of bacteria, fungi, viruses, and other microorganisms. Microbial symbiosis plays a crucial role in various ecological processes, such as nutrient cycling, pathogen resistance, and host-microbe interactions in plants and animals. Studying microbial symbiosis can provide insights into how microorganisms coexist and interact with each other in diverse environments, and how these interactions can impact the health and functioning of ecosystems.
