CT: The objective of this study was to evaluate the role of reductive acetogenesis as an alternative H2 disposal mechanism in the rumen. H2/CO2-supported acetogenic ruminal bacteria were enumerated by using a selective inhibitor of methanogenesis, 2-bromoethanesulfonic acid (BES). Acetogenic bacteria ranged in density from 2.5 × 105 cells/ml in beef cows fed a high-forage diet to 75 cells/ml in finishing steers fed a high-grain diet.

N: 1. – aceto-: before vowels acet-, word-forming element from comb. form of acetic and generally indicating compounds from or related to acetic acid.
acetic (adj.): 1808, from French acétique “pertaining to vinegar,” from Latin acetum “vinegar” (properly vinum acetum “wine turned sour;” see vinegar), originally past participle of acere “be sour,” related to acer “sharp” (see acrid).
acetate (n.): 1827, “salt formed by combining acetic acid with a base,” from Latin acetum “vinegar” (see acetic) + chemical suffix -ate (3). As a type of synthetic material, it is attested from 1920, short for acetate silk, etc.
– genesis (n.) Old English Genesis, first book of the Pentateuch, from Latin genesis, adopted as title of first book of Old Testament in Vulgate, from Greek genesis “origin, creation, generation,” from gignesthai “to be born,” related to genos “race, birth, descent” (see genus). As such, it translated Hebrew bereshith, literally “in the beginning,” which was the first word of the text, taken as its title. Extended sense of “origin, creation” first recorded in English c.1600.
2. Acetogenesis is one of the oldest metabolic processes on Earth and still has a major global significance. In this process, acetate is produced via the reduction and condensation of two carbon dioxide molecules.
