Egta → Ethylenediaminetetraacetic Acid

Participants

Reaction Steps

EGTA was purchased from the Aldrich Chemical Company (Milwaukee, Wis.). EGTA was dissolved in 0.04 M PPB according to the procedure described by Harafuji and Ogawa (J. Biochem. 87:1305-1312 (1980)). After heating EGTA for 15 minutes at 80° C., the pH was adjusted to 7.0 by addition of NaOH. EGTA was filter-sterilized using a 0.2 μm Acro disc filter (Gelman Sciences; Ann Arbor, Mich.) prior to the assay. Further dilutions were made in sterile PPB. The results of these studies, in Table D-3, show that Na2 -EDTA and EGTA were ineffective against S. typhimurium in our model on viability testing.
