Finally, we selected one strain on
the basis of its growth and rate of hydrolysis against PCL, whichwas
later on identified as Ralstonia sp. strain MRL-TL. The analysis of
biodegradation was done through scanning electron microscopy
(SEM) and fourier transform infrared (FTIR) spectroscopy after
culturing with the isolated strain, in mineral salt medium. PCLdepolymerase
from strain MRL-TL has also been purified and
characterized.
