Coal induced production of a rhamnolipid biosurfactant by Pseudomonas stutzeri, isolated from the formation water of Jharia coalbed

- Pseudomonas stutzeri was isolated from the formation water of an Indian coalbed.
- The P. stutzeri isolate produced biosurfactant in response to coal supplementation.
- The coal induced biosurfactant produced by P. stutzeri was a rhamnolipid.
- P. stutzeri produced more biosurfactant with lignite than bituminous or anthracite.
