摘要： Methods for producing bioplastics from biogas include techniques for the production of PHB using a dirty biogas (e.g., methane from landfill, digester) as both a power source for the process and as feedstock. Biogas is split into two streams, one for energy to drive the process, another as feedstock. Advantageously, the techniques may be implemented off the power grid with no dependence upon agricultural products for feedstock.

摘要： A method of selection for type II methanotrophs is provided that includes enriching a microbial feedstock using a non-sterile bioreactor with a methane source and a nitrogen source, where the microbial feedstock includes a mixture of Type I and Type II methanotrophic cells, where an inhibited growth of the Type I methanotrophic cells and an enhanced growth of the Type II methanotrophic cells forms. The method further includes exposing intermittently the enriched microbial feedstock to i) nitrate, ii) urea, or i) and ii), where enhanced growth of the Type II methanotrophs is established, and exposing the Type II methanotrophs to an unbalanced growth condition where production of polyhydroxybutyrate is induced.
