  • Process for isolating PHA from a PHA-containing bacterial biomass
    Patent number: 11834552
    Abstract: The method isolates polyhydroxyalkanoate (PHA) from a PHA-rich bacterial biomass, to the PHA isolated by the method and to a PHA having specific properties. The method treats an aqueous suspension of the PHA-rich bacterial biomass with a minimal amount of sodium hypochlorite, a methanol wash and extraction of PHA from the biomass with dimethyl carbonate (DMC).
    Type: Grant
    Filed: May 18, 2021
    Date of Patent: December 5, 2023
    Assignee: VENVIROTECH BIOTECHNOLOGY SL
    Inventors: Albert Ferrer Ugalde, Patricia Aymà Maldonado

  • Process for the preparation of glycerol carbonate
    Patent number: 10947211
    Abstract: This invention relates to a process for the preparation of glycerol carbonate from the reaction of glycerol and a dialkylcarbonate, for example dimethyl carbonate, or a cyclic alkylene carbonate. More specifically, the invention relates to a process where the synthesis of glycerol carbonate is conducted in the presence of a homogeneous transesterification catalyst and involves the partial reaction of a glycerol reactant stream and a dialkyl carbonate or cyclic alkylene carbonate reactant stream and an intermediate step of alcohol by-product separation before further reaction in order to improve glycerol conversion and glycerol carbonate selectivity and yield.
