| Description | Rudanella lutea is a gram-negative, rod-shaped bacterium that thrives at moderate temperatures, classified as a mesophile, and is a facultative anaerobe exhibiting chemoheterotrophic metabolism. This microbe is known for its versatility in adapting to different environmental conditions, allowing it to utilize various organic substrates for growth, making it a significant player in nutrient cycling within its habitats. In terms of its morphology, Rudanella lutea displays a distinctive rod shape, which aids in its motility and colonization capabilities within diverse ecosystems, particularly in aquatic environments. The gram-negative staining indicates that it possesses a thin peptidoglycan layer surrounded by an outer membrane, which not only protects the bacterium but also plays a crucial role in its interactions with the surrounding environment, including resistance to certain antibiotics. The mesophilic preference of Rudanella lutea allows it to thrive at moderate temperatures, typically ranging from 20°C to 45°C. This temperature range is common in many natural and anthropogenic environments, contributing to its adaptability and ecological relevance. As a facultative anaerobe, Rudanella lutea can utilize oxygen for respiration when available but can also ferment organic compounds in oxygen-limited conditions, making it well-suited for survival in fluctuating environments. Rudanella lutea has been found in various ecological niches, including freshwater and marine settings, as well as in sediments rich in organic matter. Its chemoheterotrophic nature allows it to decompose organic materials, playing a vital role in biogeochemical cycles. Additionally, this microbe can produce yellow-pigmented colonies, which is a notable characteristic, and this pigmentation may contribute to its interactions with other microorganisms and its ability to absorb light and various wavelengths, potentially influencing its ecological dynamics. |
