초록

Embodiments of the invention relate generally to methods to generate microorganisms and/or microorganism cultures that exhibit the ability to produce polyhydroxyalkanoates (PHA) from carbon sources at high efficiencies. In several embodiments, preferential expression of, or preferential growth of microorganisms utilizing certain metabolic pathways, enables the high efficiency PHA production from carbon-containing gases or materials. Several embodiments relate to the microorganism cultures, and/or microorganisms isolated therefrom.

1. A method for enhancing polyhydroxyalkanoate (PHA) production in a methanotrophic culture by reducing copper concentrations to effect particulate methane monooxygenase (pMMO) production, the method comprising: (a) contacting a culture of methanotrophic microorganisms with a medium comprising copper, one or more additional nutrients, and a carbon-containing gas that can be metabolized by said culture;(b) incubating said culture in said medium to cause growth of said culture; and(c) inducing a selection pressure on said culture to transform said culture ...
