Light micrograph of isolate BInIXT grown in ST-medium for 12 h at 37 °C. - Source:5

Short-chain fatty acids

POSNEGVariableNot assessed


Strictly anaerobic, chemoorganotrophs with a fermentative metabolism 6. Sugars are mainly utilised as carbon sources for growth 6 7 3 1 5 8 2 9 10 11. Some species may utilise H2/CO2 as a major energy source and produce acetate 6 1 2. Cells of Blautia are cocci 12 to coccobacilli 6 10 9, which can occur singly, in pairs 1 and sometimes in short-long chains 7 5 8 2 13 3. No physiological information is known for the genus in activated sludge.
