Bacillus subtilis strain NRS 231

Bacillus subtilis strain NRS 231 is a Gram-positive, rod-shaped bacterium that exhibits facultative anaerobic respiration. This strain is motile, possessing flagella that enable movement. It thrives optimally at a temperature of 25°C and is classified as mesophilic, indicating it grows well in moderate temperature ranges. NRS 231 is notable for its ability to sporulate, a trait that allows it to survive in adverse conditions by forming resilient spores. This characteristic is advantageous for its survival in various habitats, particularly as it is host-associated and can inhabit diverse organisms. The strain has been identified in association with several hosts, including Gallus gallus (chickens), various plants such as Viridiplantae, Triticum aestivum (wheat), Solanum lycopersicum (tomato), Phaseolus vulgaris (common bean), Salmo salar (Atlantic salmon), Theobroma cacao (cocoa), Fagonia indica, and Camellia reticulata. With a biotic relationship classified as free-living, B. subtilis NRS 231 contributes to the microbial community in the environments it inhabits. The presence of two replicons suggests a complex genetic architecture, which may be related to its adaptability and ecological roles. The diverse range of hosts indicates that this strain could play significant roles in nutrient cycling and plant health, potentially benefiting agricultural practices through its interactions with crops. Thus, B. subtilis NRS 231 exemplifies the intricate relationships between microorganisms and their environments, highlighting the importance of microbial diversity in ecological systems.
