Bacillus subtilis strain HM-66

Bacillus subtilis strain HM-66 is a facultatively anaerobic, gram-positive bacterium characterized by its rod shape and the presence of flagella, which facilitates its mobility. This strain thrives optimally at 25°C and falls within the mesophilic temperature range. It possesses a single replicon and a single membrane, and it is known for its ability to sporulate, which is a key survival mechanism under unfavorable conditions. This bacterium is classified as free-living, indicating that it does not rely on a specific host for survival. However, it has been isolated from various hosts, including the domestic chicken (Gallus gallus), several plant species such as Triticum aestivum (wheat), Solanum lycopersicum (tomato), and Theobroma cacao (cacao), as well as the fish Salmo salar (salmon) and the plant Fagonia indica. This wide range of host associations suggests that Bacillus subtilis strain HM-66 may play significant roles in various biological and ecological contexts, such as plant growth promotion, nutrient cycling, and disease suppression in both terrestrial and aquatic ecosystems. The diverse habitats and biotic relationships of Bacillus subtilis strain HM-66 underscore its ecological importance. Its ability to interact with a variety of hosts contributes to its role as a beneficial microorganism in agriculture and aquaculture, highlighting its potential applications in sustainable practices. The strain's adaptability and sporulation capability further enhance its resilience in fluctuating environments.
