Effect of Drying Mode of Bacterial Biomass on the Effectiveness of Extraction and Physicochemical Properties of the Product (Polymer)
Comparative study of different drying modes of bacterial biomass of Cupriavidus eutrophus В10646 was conducted. Different modes differently affect the yield of the product (polymer) and its physicochemical properties (molecular weight distribution and temperature characteristics). High temperatures...

| description | Comparative study of different drying modes of bacterial biomass of Cupriavidus eutrophus В10646 was conducted. Different modes differently affect the yield of the product (polymer) and its physicochemical properties (molecular weight distribution and temperature characteristics). High temperatures caused the polymer degradation and decrease of its molecular weight. Using freeze drying allows to obtain friable biomass with an extended surface which is favorable for extraction process and to preserve the molecular weight characteristics of the polymer |
