ABSTRACT:
A process for producing biopolymers comprises passing nitrogen deficient wastewater through a treatment system comprising micro-organisms which grow aerobically in nitrogen deficient wastewater, and controlling the environment in the treatment system by maintaining a sufficiently stable dissolved oxygen level to thereby encourage the growth and/or activity of micro-organisms which produce the biopolymers, and recovering the biomass produced and the biopolymers.
