'''Eubacterium maltosivorans SA11'''

Eubacterium maltosivorans SA11 (formerly Eubacterium limosum, and sheep acetogen SA11) was isolated from the rumen of a New Zealand sheep grazing fresh forage [1]. SA11 is a metabolically versatile bacterium able to grow on a wide variety of compounds including CO<sub>2</sub>/H<sub>2</sub>, formate, glucose, fructose, xylose, ribose, maltose, pyruvate, L-lactate, methanol, vanillate, syringate, and 3,4,5-trimethoxybenzoatehexoses. Acetate and butyrate are the main fermentation end products [2]. A feature of the SA11 genome is the presence of multiple copies of genes encoding trimethylamine methyltransferase family proteins (COG5598). SA11 has 39 genes in this category, but in most cases their substrate is not known. The genome contains a 55 kb prophage and genes required for the metabolism of 1,2 propanediol.

The SA11 genome consists of a single 4,150,332 bp circular chromosome [2].
