  1. 1. Concentration of Proteins and Decrease of Salt Content in a Hydrolyzed Fermentation Broth Using Membrane Filtration

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Linnea Sjökvist; [2023]
    Nyckelord :Membrane filtration; ultrafiltration; PHA; polyhydroxyalkanoates; chemical engineering; Technology and Engineering;

    Sammanfattning : Membrane filtration was used to concentrate proteins and decrease the salt concentration in a hydrolyzed fermentation broth. The broth was a by-product from the bacterial production and extraction of polyhydroxyalkanoates (PHA), that can be used to produce biobased plastics. LÄS MER

    Nyckelord :biosurfactant; rhamnolipids; HPLC; HPAEC-PAD; bacteria growth; downstream purification; liquid-liquid extraction; biotechnology; Chemistry;

    Sammanfattning : The main aim of this master project is to find out whether strain Geobacillus 7349 can produce biosurfactant during their growth by extraction and characterization of the product. The other goal is to optimize the cultivation condition of the strain. LÄS MER

  4. 3. Tillsyn av kemiska produkter i detaljhandeln: Kontroll av barnskyddande förslutning och kännbar varningsmärkning på kemiska produkter i Burlövs kommun

    Magister-uppsats, Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Melisa Dracic; [2023]
    Nyckelord :Kemiska produkter; Barnskyddande förslutning; Kännbar varningsmärkning; Tillsyn; Earth and Environmental Sciences;

    Sammanfattning : Each year children and adults are injured in accidents caused by chemicals, usually due to incorrect use of the products. Studies have shown that children are more sensitive to chemical products and injuries that occur during childhood could cause lifelong consequences. LÄS MER

  5. 4. Production of polymers from a papermills wastewater using HTC substrate. : Investigating the viability of using wastewater sludge from Skoghalls’ papermill in combination with filtrate from HTC of sewage sludge to produce biological plastic producing polymers.

    Kandidat-uppsats, Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik

    Författare :Regan George; [2023]
    Nyckelord :PHA; HTC-substrate; Polymer;

    Sammanfattning : Since their conception, plastics have been a dominant product due to the versatility of use, and readily available raw materials. However, the production and consumption of synthetic plastics have continued to increase over the years, leading to a significant rise in plastic waste and its associated environmental impacts, such as the detrimental effects plastic waste has on ecosystems, including the presence of toxic microplastics and risks to marine life, are becoming the focus of criticism.
