A new episomic element controlling fermentative metabolism and excretion of amino acids by Citrobacter intermedium C3.
Glutamate excretion by colonies of Citrobacter intermedium C3 was detected by using the auxotrophic strain Leuconostoc mesenteroides P-60. A constant ratio of strain C3 colonies did not excrete glutamate. These colonies were subcultured, and colonial analysis of their descendants established that the change from non-excretor to excretor (Sg(-) --> Sg(+)) is a spontaneous and random process with...

Metabolism and Nutrition: Amino Acids
In the United States, guinea fowl (GF) production has continued to increase due to increased demand and consumption of specialty meats . However, there is lack of information on optimum nutrients, such as amino acids, that would support optimum growth performance and minimize production cost of the GF . The amino acid methionine is most limiting in poultry feeding while methionine and cysteine ...
متن کاملMetabolism and Nutrition: Amino Acids
Feed accounts for 60 to 70% of broiler production costs . Thus, improvement in feed efficiency is needed. Ileal digestibility (ID) and total-tract amino acid (AA) utilization are the parameter used to evaluate feed ingredients . However, ID of AA can be affected, for example, by gut inflammation as a result of a coccidial vaccine challenge. Adedokun et al. (2014) showed significantly high ileal...
