Description

Proteiniphilum are facultatively anaerobic 1, fermenters 3. They are proteolytic bacteria that utilise proteins, yeast extract, pyruvate 3 and carbohydrates 1 as substrates for anaerobic growth in pure culture. Alcohols and most fatty acids are not utilised 3. Acetic acid is produced from the fermentation of yeast extract, peptone 3 1, pyruvate, glycine, and L-arginine 3. Cells of Proteiniphilum are rods, which occcur singly or in pairs. Occassionally, P. saccharofermentans forms filamentous cells in pure culture 1.
