Microbial synthesis of polyhydroxyalkanoate using seaweed-derived crude levulinic acid as co-nutrient

- Seaweed derived crude levulinic acid (SDCLA) as co-substrate with biodiesel waste.
- Highest polymer yield of 1.07 g with 0.35% (w/v) SDCLA + biodiesel waste.
- Incorporation of high levels of 3-hydroxy valerate (81%), altered the polymer.
- The carbon uptake in form of PHA was 57.5% of the total organic carbon consumed.
- Biodegradability of the obtained co-polymer film was faster than the control film.
