An Exceptionally Large Pyoverdin from a Pseudomonas Strain Collected in Thailand+

So far all pyoverdins with a C-terminal cyclopeptidic substructure have in common that the ε -amino group of an in-chain Lys is bound amidically to the carboxyl group of a C-

Observation of both tensio-active and emulsifying activities indicated that biosurfactants were produced by the newly isolated and promising strain Pseudomonas putida 21BN.

We show here that the newly isolated strain Pseudomonas putida 21BN produces a surfactant which substantially changes the surface tension of the culture meduim when grown

These compounds represent diverse classes of chemical struc- tures and provide evidence for the untapped biosynthetic potential of marine bacteria
