The myeloid lineage to which HL-60 promyelocytic leukemia cells will differentiate in response to a chemical differentiation inducer can be switched by altering the pH of the growth medium. Cells passaged previously at pH 7.2 become neutrophiles, and those passaged previously at pH 7.6 become eosinophiles after 5 to 7 days of culture in the presence of 0.5 mM butyric acid. Butyric acid and its ...
Biosynthetic pathways of ebelactone A and B were studied by 13C NMR spectroscopy. By using 13C labeled compounds as precursors it was determined that ebelactone A was derived from one molecule of acetic acid and six propionic acids and ebelactone B from one molecule of acetic acid, five propionic acids and one butyric acid.
UNLABELLED Clostridium tyrobutyricum is a Gram-positive anaerobic bacterium that efficiently produces butyric acid and is considered a promising host for anaerobic production of bulk chemicals. Due to limited knowledge on the genetic and metabolic characteristics of this strain, however, little progress has been made in metabolic engineering of this strain. Here we report the complete genome se...
This study was designed to separate the effect of fermentation quality on voluntary intake of grass silage from other feed factors affecting intake. Variations in DMI were quantified, and the impact on intake was modeled. The relationships between individual silage components and intake were examined. A partially balanced changeover experiment with 30 Norwegian Red steers (137 +/- 16.4 kg of BW...
