Abstract:
1. A method for producing a polyhydroxyalkanoate (PHA) in a culture of methanotrophic microorganisms, the method comprising: a) providing a gas comprising methane and one or more non-methane substances; b) providing a culture of methanotrophic microorganisms; c) providing a microorganism culture medium comprising at least a first essential nutrient and a second essential nutrient; d) exposing said culture to said gas; e) controlling the concentration of said first essential nutrient in said culture medium to a concentration sufficient to induce said methanotrophic microorganisms to produce particulate methane monooxygenase (pMMO) or soluble methane monooxygenase (sMMO); and f) controlling the concentration of said second essential nutrient, wherein said control of said second essential nutrient causes said methanotrophic microorganisms to produce said PHA.
