Duke University scientist Bruce Donald and colleagues recently announced the successful application of their K* algorithm to engineer new versions of an enzyme involved in the production of a natural antibiotic called gramicidin S.
Some evidence such carriers cases detected gramicidin brain on gramicidin s benign.
Synge has shown this in some very beautiful investigations on the structure of gramicidin, an antibiotic active against certain bacteria.
From 1942 to 1948 he worked almost exclusively with the antibiotic peptides of the gramicidin group.
For perforated patch-clamp recordings, gramicidin-D (50 mg/ml in dimethylsulfoxide) was dissolved at 50 µg/ml in the internal medium.
- Constructed with liquid crystalline gramicidin and blue / purple filters.
- Constructed with liquid crystalline gramicidin, hardened epoxy, and blue / purple filters.

In 1939 and 1944, they purified the antibiotics gramicidin and streptomycin from soil samples, in Waksman’s case, from a farmyard where chickens had gotten sick.4
