The anaerobic monotrichous butyric acid-producing curved rod-shaped bacteria of the rumen.
During studies of bacteria isolated from rumen contents, several workers have encountered anaerobic, gram negative, butyric acid-producing curved rods (Hungate, 1950; Huhtanen and Gall, 1952; and Wilson, 1953). Bryant and Burkey (1953a) published brief descriptions of three groups of anaerobic, motile, curved rods. Further studies have shown that four fundamentally different kinds of bacteria w...
متن کاملMore monensin-sensitive, ammonia-producing bacteria from the rumen.
Two monensin-sensitive bacteria which utilized carbohydrates poorly and grew rapidly on amino acids were isolated from the bovine rumen. The short rods (strain SR) fermented arginine, serine, lysine, glutamine, and threonine rapidly (greater than 158 nmol/mg of protein per h) and grew faster on casein digest containing short peptides than on free amino acids ().34 versus 0.29 h(-1)). Gelatin hy...
متن کاملConstruction and characterization of shuttle vectors for succinic acid-producing rumen bacteria.
Shuttle vectors carrying the origins of replication that function in Escherichia coli and two capnophilic rumen bacteria, Mannheimia succiniciproducens and Actinobacillus succinogenes, were constructed. These vectors were found to be present at ca. 10 copies per cell. They were found to be stably maintained in rumen bacteria during the serial subcultures in the absence of antibiotic pressure fo...
متن کاملThe Aerobic Dissimilation of Lactic Acid by the Propionic Acid Bacteria.
The hydrogen reacts with lactic acid to form propionic acid. Pyruvic acid has been isolated from the fermentation of glucose (1934) and of lactic acid (unpublished data) by Wood and Werkman. These investigators supported Van Niel's proposed dissimilation of pyruvic acid inasmuch as the occurrence of acetaldehyde could not be demonstrated. Little information is available concerning the aerobic d...
متن کاملDisappearance and passage of propionic acid from the rumen of the beef steer.
Studies were conducted to define steady state pH, propionic acid concentrations and fluid turnover in the rumen of steers fed every 3 h and to determine whether rates of ruminal propionic acid disappearance were linearly related to their in situ production rates. Ruminally fistulated beef steers (326 +/- 11 kg; n = 3) were fed eight times daily a 54% mixed hay: 46% corn-based concentrate diet t...
