    Abstract: The present invention relates to a method for cultivating a microorganism capable of utilizing an organic feedstock, comprising the steps of: (i) cultivating the microorganism in one or more bioreactors (1); (ii) capturing CO2 from the one or more bioreactors (1) and reducing the CO2 to an organic feedstock in a reduction unit (3); and (iii) feeding at least a part of the organic feedstock from the reduction unit (3) into one or more bioreactors (1).

    Abstract: The present invention is directed to a process for obtaining a lipid from a composition comprising microbial cells, the process comprising: treating the composition comprising microbial cells to a temperature of about 60° C. to about 95° C. at a pH of about 9 to about 11; separating the treated microbial cells into a light phase and a heavy phase; sequentially, in one or more cycles, raising the pH of the concentrated microbial cell composition to 10 or above, followed by lowering the pH of the concentrated microbial cell composition to a pH of less than 6 to lyse the concentrated microbial cell composition, wherein the raising and lowering of the pH also demulsifies the concentrated microbial cell composition; separating the lipid from the demulsified cell composition, and recovering the lipid.

    Abstract: The present invention relates to a process for preparing a granular nylon salt material, wherein an aqueous mixture, comprising at least 65 wt. % of salt components, and at most 35 wt. % of an aqueous medium, the weight percentages (wt. %) being relative to the total weight of the aqueous mixture, is flashed from a pressure vessel via a flash valve into a flash chamber, thereby evaporating the aqueous medium in an amount sufficient to result in a residual moisture content of at most 7.5 wt. %, and forming a granular nylon salt material. The invention also relates to a process for preparing a nylon polymer, comprising direct solid state polymerization of the granular salt material prepared by flash granulation.

    Abstract: A recombinant host capable of producing a steviol glycoside which overexpresses a polypeptide which mediates steviol glycoside transport and which polypeptide comprises the amino acid sequence set forth in SEQ ID NO: 35 or SEQ ID NO: 38 or an amino acid sequence having at least about 50% sequence identity to either thereto. A recombinant host capable of producing a steviol glycoside which has been modified, preferably in its genome, to result in a deficiency in the production of a polypeptide which mediates steviol glycoside transport and which polypeptide comprises the amino acid sequence set forth in SEQ ID NO: 35 or SEQ ID NO: 38 or an amino acid sequence having at least about 50% sequence identity to either thereto.

    Abstract: The invention relates to a foamed composition comprising a thermoplastic copolyester elastomer, wherein the foamed composition has a relative solution viscosity of at least 4.1 as measured according to ISO 1628-5:2015 and wherein the thermoplastic copolyester elastomer comprises hard segments built up from polyester repeating units derived from at least one aliphatic diol and at least one aromatic dicarboxylic acid or an ester thereof and soft segments being polytetramethylene oxide. The invention also relates to a process for preparing the foamed composition.
