Two co-cultures, each of a coccobacillus plus a Gram-negative rod, were isolated from a cattle waste digester. The cultures were distinguished by production of methane from acetate only, or from either acetate or butyrate. 2-Methylbutyrate, added initially as a growth factor, was degraded to propionate but only during growth on acetate or butyrate. Valerate and 2- and 3-methyl valerate were not degraded.
