Production of biosurfactants by the resting cells of Pseudomonas aeruginosa CFTR-6.

A resting cell system was used for the production of
glycolipids by ........... aerugin~a CFTR-6. In this, the
growth phase was separated from the production phase to overcome
the inhibition of glycolipid production by inorganic phosphate.
It was shown that when the cells were transferred after the
growth phase into a medium devoid of phosphate, glycolipid
production was increased nearly twofold. The maximum glycolipid
concentration was attained much more rapidly than the
conventional batch fermentation system, thus increasing the
productivity.
