| Description | Succinivibrio dextrinosolvens is a gram-negative, rod-shaped bacterium that thrives at mesophilic temperatures, is classified as a chemoheterotroph, and is an obligate anaerobe. This microbe is primarily found in the intestines of various mammals, contributing to the complex gut microbiota, though it can also be isolated from other environments rich in organic matter, such as ruminal fluid in herbivores. As a gram-negative bacterium, S. dextrinosolvens possesses a thin peptidoglycan layer surrounded by an outer membrane, which contains lipopolysaccharides. This structure not only plays a crucial role in its resistance to environmental stresses but also influences its interactions with the host’s immune system. Being rod-shaped, these cells exhibit a characteristic bacillus morphology, which aids in motility and colonization in diverse environments. As a mesophilic organism, S. dextrinosolvens optimally grows in moderate temperature ranges, typically between 30°C and 40°C, aligning well with the body temperature of its hosts. Its classification as a chemoheterotroph indicates that it obtains its energy through the oxidation of organic compounds, which are vital for its metabolism and growth. The obligate anaerobic nature of this bacterium means it thrives in environments devoid of oxygen, relying on fermentation processes to generate energy, resulting in beneficial by-products such as short-chain fatty acids. This microbe plays an essential role in the digestive processes of herbivores, particularly in the breakdown of complex carbohydrates, assisting in nutrient absorption. Furthermore, its capacity to synthesize succinate, a key intermediate in numerous metabolic pathways, aids in maintaining the microenvironment in the gut, promoting the growth of beneficial microbes while inhibiting harmful ones. |
