Abstract
A Gram-positive bacterium was isolated from a marine soil sample collected from
Porbandar, Gujarat, India and identified as Rhodococcus pyridinivorans (OK036732)
using 16S rRNA sequencing. The present study evaluates the ability of R. pyridinivorans
to utilize various natural waste carbon sources for biosurfactant production and
hydrocarbon biodegradation.
Among the tested substrates, orange peel proved to be the most effective, yielding
1.25 g/L of biosurfactant with an emulsification activity of 69.62% against the
tested hydrocarbon. Biodegradation studies indicate that the biosurfactant produced
by R. pyridinivorans holds significant promise as an environmental friendly and
biodegradable alternative.
