The vitamin requirements of staphylococci have been studied by numerous investigators with considerable diversity of results. Much of this confusion undoubtedly results from the failure of most such studies to consider the physiological characteristics of the organisms investigated. The classical investigations of Knight (1937) showed that strains of Staphylococcus aureus required thiamin and n...
Virtanen and Laine (1937) were the first to suggest the existence of an aspartic acid decarboxylase in Rhizobium trifolii, by the isolation of beta-alanine from a 47-day fermentation mash containing aspartic acid. Shive and Macow (1946), working with hydroxyaspartic acid as a competitive analogue for aspartic acid in the metabolism of Escherichia coli, found that the addition of this compound t...
Two experiments evaluated effects of added pantothenic acid on performance of growing-finishing pigs. In Exp. 1, 156 pigs (PIC, initial BW = 25.7 kg) were used in a 3 x 2 x 2 factorial to evaluate the effects of added pantothenic acid (PA; 0, 22.5, or 45 ppm), ractopamine.HCl (RAC; 0 or 10 mg/kg), and sex on growth performance and carcass traits. Pigs were fed increasing PA from 25.7 to 123.6 k...
