  1. 1. Assessment of promoter regulation in Pseudomonas putida using GFP and flow cytometry

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Luka Cululejevic; [2022]
    Keywords : applied microbiology; Pseudomonas putida; promoter characterization; aromatic compounds; vanillin; guaiacol; Biology and Life Sciences;

    Abstract : Lignin is found in all biomass and is an abundant natural source of aromatic compounds. It has the potential to serve as a renewable raw material for a variety of chemicals currently derived from fossil fuel sources such as muconic acid, an important platform chemical. Kraft lignin is a waste stream from the pulp and paper industry. READ MORE

  3. 2. Recycling of Textile and Plastic from an Interior Vehicle Component

    University essay from KTH/Fiber- och polymerteknologi

    Author : Esther Wennerstrand; [2021]
    Keywords : Polycarbonate; ABS; poly ethylene terephthalate ; mechanical recycling; chemical recycling; Polykarbonat; ABS; polyetylentereftalat; mekanisk återvinning; kemisk återvinning;

    Abstract : På grund av den rådande klimatförändringen och de globala problem som plast orsakar i miljön blir det allt viktigare att dagens linjära materialanvändning ändras till en cirkulär användning. Inom fordonsindustrin har kravet på ökad tillgänglighet och kvalitet på återvunna material identifierats. READ MORE

  4. 3. Oxidation of cellulose to favour its dissolution in alkaline aqueous solution before regeneration into textile yarn

    University essay from KTH/Kemiteknik

    Author : Martin Orpiszak; [2021]
    Keywords : Cellulose; periodate oxidation; dissolution; regeneration; textile yarn; cellulosa; natriumperjodat oxidation; upplösning; regenerering; textilgarn;

    Abstract : Detta examensarbete är en del av CelluFil-projektet och syftar till att optimera förhållandena för upplösning av cellulosa i vattenlösning av natriumhydroxid följd av regenering i form av ett garn. Tidigare arbeten har visa tatt cellulosa kan lösas i vattenlösning vid -10°C, men sådana förhållanden är inte tillämpliga i industriell skala. READ MORE

  5. 4. Feasibility Study of a Technology for Catalytic Low Pressure Depolymerization of Biomass to Diesel in Thailand

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Kusuma Wongmaha; [2018]
    Keywords : ;

    Abstract : The study has been conducted in collaboration with Swestep AB, a Swedish company that specializes in the conversion of waste to valuable products via the KDV technology. The study explores the possibility of using cassava chips and cassava pulp as a potential feedstock in the production of synthetic diesel and compares the KDV method with fermentation, a conventional method of using cassava chips and cassava pulp in Thailand.

  6. 5. Construction of Gene Libraries from Environmental Isolates for expression in Pseudomonas putida

    University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Author : Helga Helgadóttir; [2018]
    Keywords : applied microbiology; teknisk mikrobiologi; Biology and Life Sciences; Technology and Engineering;

    Abstract : Currently most aromatic compounds used in industry are derived from unsustainable petro-chemical feedstock. However the depolymerization of lignocellulosic biomass generates a wide range of aromatic compounds that could be further valued through microbial conversion with microorgansims such as the bacterium Pseudomonas putida.
