A method for the production of a polyhydroxyalkanoate material from one or more non-methane volatile organic compounds (VOCs), comprising: a) providing one or more non-methane VOCs; b) providing one or more first microorganisms capable of oxidizing said one or more VOCs to produce an oxidized compound, wherein said first microorganisms are methane-oxidizing microorganisms, wherein said first microorganisms are capable of using methane as a source of carbon or energy for growth, but do not use said one or more non-methane VOCs as a source of carbon or energy for growth; c) providing one or more second microorganisms capable of incorporating a carbon contained within said oxidized compound into a PHA material, wherein said second microorganisms are PHA-synthesizing microorganisms; d) providing a growth-culture medium that regulates the metabolism of said one or more first microorganisms and said one or more second microorganisms; e) exposing said one or more first microorganisms in said growth-culture medium to said one or more non-methane VOCs, thereby causing or allowing said one or more first microorganisms to convert said one or more non-methane VOCs into said oxidized compound; f) altering the availability of copper to said one or more first microorganisms either by increasing the availability of copper to said one or more first microorganisms, thereby causing said one or more first microorganisms to produce particulate methane monooxygenase (pMMO), or by decreasing the availability of copper to said one or more first microorganisms, thereby causing said one or more first microorganisms to produce soluble methane monooxygenase (sMMO); g) contacting said oxidized compound with said second microorganisms; and h) manipulating said growth-culture medium to cause or allow said one or more second microorganisms to use said carbon contained within said oxidized compound for the production of said PHA material. a) providing one or more non-methane VOCs; b) providing one or more first microorganisms capable of oxidizing said one or more VOCs to produce an oxidized compound, wherein said first microorganisms are methane-oxidizing microorganisms, wherein said first microorganisms are capable of using methane as a source of carbon or energy for growth, but do not use said one or more non-methane VOCs as a source of carbon or energy for growth; c) providing one or more second microorganisms capable of incorporating a carbon contained within said oxidized compound into a PHA material, wherein said second microorganisms are PHA-synthesizing microorganisms; d) providing a growth-culture medium that regulates the metabolism of said one or more first microorganisms and said one or more second microorganisms; e) exposing said one or more first microorganisms in said growth-culture medium to said one or more non-methane VOCs, thereby causing or allowing said one or more first microorganisms to convert said one or more non-methane VOCs into said oxidized compound; f) altering the availability of copper to said one or more first microorganisms either by increasing the availability of copper to said one or more first microorganisms, thereby causing said one or more first microorganisms to produce particulate methane monooxygenase (pMMO), or by decreasing the availability of copper to said one or more first microorganisms, thereby causing said one or more first microorganisms to produce soluble methane monooxygenase (sMMO); g) contacting said oxidized compound with said second microorganisms; and h) manipulating said growth-culture medium to cause or allow said one or more second microorganisms to use said carbon contained within said oxidized compound for the production of said PHA material.
