| AC medium |
General growth medium. Peptone, beef extract, yeast
extract, malt extract, dextrose, ascorbic acid, 0.1% agar, pH 7.2.
AC Broth does not have agar. |
| ACES |
(2-[(2-amino-2-keto-ethyl)amino]ethanesulfonic acid.
Buffer for pH range 6.1-7.5 |
| Acid food |
Generally, a food with pH naturally < 4.0, so that it is (relatively) safe
from bacterial spoilage |

N-[2-acetamido]-2-iminodiacetic acid; Buffer for pH
range 6.0-7.2 |
| Agar diffusion |
(1) a procedure for detecting growth inhibitors (antibiotics)
by measuring the diameter of a zone of inhibition around a sample
of growth inhibitor on an agar plate. (2) a procedure for detecting
antigen-antibody reactions from samples diffusing toward each other
through agar |
| Agar droplet (count) |
Counting procedure in which the a dilution of sample
is placed (at increasing dilutions) into three tubes of melted agar.
Small droplets of the agar are placed on the bottom of a Petri dish,
incubated, and examined under magnification. |
| Agar, Noble |
Specially washed agar, by the method of Noble and Tonney.
Highly purified. |

| ARS |
Autonomously replicating sequence (DNA) |
| ATP |
Adenosine triphosphate. |
| ATP assay |
A procedure for detecting living cells by
using their ATP content to excite chemiluminescence, typically
with the luciferin/luciferase reaction. |
| ATS medium |
