| Description | Ruminococcus sp. SR1/5 is a fascinating microorganism that thrives in temperatures ranging from mesophilic to thermophilic conditions, classified as a thermophilic microbe (Temperature preference category: Thermophile). It is a chemoheterotroph, meaning it obtains energy by breaking down organic matter, specifically by fermenting a wide range of carbohydrates, as its primary energy source. This microbe produces energy through anaerobic respiration, utilizing ATP-generating pathways such as substrate-level phosphorylation and electron transport. A Gram-positive microorganism, Ruminococcus sp. SR1/5 exhibits a characteristic shape of curved or comma-shaped rods. Its morphology is reminiscent of a coccus, with a single cell often resembling a small, curved sphere. As a fermentative microbe, it is found in various body sites, including the gastrointestinal tract, oral cavity, and skin, across all possible species. Ruminococcus sp. SR1/5 is an obligate anaerobe, requiring an environment devoid of oxygen to survive. It is also oxygen-tolerant, able to withstand the presence of oxygen without being harmed, but it cannot metabolize in the presence of oxygen. Furthermore, it has a unique ability to thrive in environments with low redox potential, often found in the gastrointestinal tract. In the gastrointestinal tract, this microbe plays a crucial role in the breakdown of complex carbohydrates, such as cellulose and hemicellulose, into simpler sugars, which are then absorbed and utilized by the host. Its presence also contributes to the production of short-chain fatty acids, which act as energy sources for the host and regulate the gut microbiome. Ruminococcus sp. SR1/5 has been found to produce a variety of enzymes, including cellulase, xylanase, and amylase, which enable it to degrade complex carbohydrates. Its ability to thrive in the gastrointestinal tract, where oxygen levels are low, suggests its potential as a probiotic for the treatment of various gastrointestinal disorders. |
