Recycling of Waste Streams of the Biotechnological Poly(hydroxyalkanoate) Production by Haloferax mediterranei on Whey

Figure 2

Scheme of a closed recycling system for reutilization of waste streams from fermentative PHA production process by H. mediterranei based on the feedstock whey. The saline supernatant SSF should be used to partly replace mineral compounds in subsequent fermentation processes, whereas salty (SF) or salt-free (SD) cell debris should be used as nitrogen and phosphate source in order to reduce the required amount of yeast extract.
