The one or more bacterial cells of claim 1, wherein said PHA is poly 3-hydroxybutyrate-co-3-hydroxyvalerate (PHBV), medium-chain-length PHA (mcl-PHA), short-chain-length PHA (scl-PHA), or combinations thereof. 6. The one or more bacterial cells of claim 5, wherein said scl-PHA is polyhydroxybutyrate (PHB). 7. The one or more bacterial cells of claim 1, wherein said PHA is poly 3-hydroxybutyrate-co-3-hydroxyvalerate (PBV). 8. A composition comprising the one or more bacterial cells of claim 1. 9. The composition of claim 8 further comprising one or more strains, wherein said one or more bacterial cells promote the ability of said one or more strains to produce PHA. 10. An isolated microbial consortium comprising the one or more bacterial cells of claim 1. 11. The isolated microbial consortium of claim 10, further comprising one or more strains, wherein said one or more bacterial cells promote the ability of said one or more strains to produce PHA. 12. A composition comprising the isolated microbial consortium of claim 10.
