Enrichment of mixed methanotrophic cultures producing polyhydroxyalkanoates (PHAs) from various environmental sources.

Methanotrophic bacteria can use atmospheric methane (CH) as a sole carbon source for the growth and production of polyhydroxyalkanoates (PHA). The development of CH bioconversion processes relies heavily on the selection of an efficient methanotrophic culture. This research assessed the effect of selected growth conditions, such as nitrogen sources on the enrichment of methanotrophic cultures from various environments for PHA accumulation.

Recent trends in methane to bioproduct conversion by methanotrophs.

Methane is an abundant and low-cost gas with high global warming potential and its use as a feedstock can help mitigate climate change. Variety of valuable products can be produced from methane by methanotrophs in gas fermentation processes. By using methane as a sole carbon source, methanotrophic bacteria can produce bioplastics, biofuels, feed additives, ectoine and variety of other high-value chemical compounds.

Production of Raw Starch-Digesting Amylolytic Preparation in and Its Application in Biotechnological Synthesis of Lactic Acid and Ethanol.

Sustainable economy drives increasing demand for raw biomass-decomposing enzymes. Microbial expression platforms exploited as cellular factories of such biocatalysts meet requirements of large-volume production. Previously, we developed recombinant strains able to grow on raw starch of different plant origin.
