| Description | Bacillus nealsonii is a gram-positive, rod-shaped bacterium that thrives at moderate temperatures, classified as a mesophilic organism that prefers an environment rich in organic matter. This microbe is considered a chemoheterotroph, obtaining its energy through the oxidation of organic compounds, and can grow in a variety of environments, including soil, water, and even in association with plant roots. As a gram-positive organism, *Bacillus nealsonii* possesses a thick peptidoglycan layer in its cell wall, which is characteristic of this group. This structural feature not only provides rigidity but also influences its response to antibiotics. Its rod shape, typical of many bacilli, contributes to its mobility and ability to colonize various habitats effectively. The mesophilic temperature preference indicates that it thrives best between 20°C to 45°C, a range that coincides with many natural and human-modified environments. Being a chemoheterotroph means that *Bacillus nealsonii* relies on organic substrates for both carbon and energy, making it an essential player in nutrient cycling within ecosystems. This bacterium is classified as a facultative anaerobe, allowing it to grow in both the presence and absence of oxygen. This adaptability enables it to inhabit diverse ecological niches, from oxygen-rich environments to more anaerobic conditions. Beyond its ecological roles, *Bacillus nealsonii* has garnered interest for its potential in bioremediation and agriculture. Its ability to degrade organic pollutants and promote plant growth through various biochemical pathways makes it a candidate for sustainable practices. Furthermore, studies have indicated that it may produce biologically active compounds that could contribute to disease resistance in plants, highlighting its potential applications in improving agricultural productivity. |
