  1. 1. Production, Purification, and Characterization of wood substrates and Galactose oxidase enzyme

    University essay from KTH/Industriell bioteknologi

    Author : Rakhesh Pongalikonnar Ranganathan; [2023]
    Keywords : Peracetic acid treatment; Galactose oxidase; Pichia pastoris; Biomass recalcitrance; Enzymatic upgrading; Perättiksyrabehandling; Galaktosoxidas; Pichia pastoris; Motsträvighet i biomassa; Enzymatisk uppgradering;

    Abstract : Trä är den bästa förnyelsebara källan för att producera många produkter på grund av dess biokompatibla och biologiskt nedbrytbara natur. Träets biomassa har en motstridig natur mot enzymatisk uppgradering. READ MORE

  3. 2. Produktion av biofilm med MRSA, MRSP eller Campylobacter jejuni, samt hur olika desinfektionsmedel påverkar den

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Moa Therése Viklund; [2022]
    Keywords : biofilm; destruktion av biofilm; Campylobacter jejuni; stafylokocker; MRSA; MRSP; desinfektion; rengöring; peroxymonosulfat buffrade syror; perättiksyra; väteperoxid; hypoklorsyra; etanol;

    Abstract : I denna studie ingick såväl produktion av biofilm i en statisk modell med mikrotiterplattor där biofilmen fick växa ostört i 5 dagar i inkubationsskåp i 30 °C, samt en mer dynamisk modell. I den dynamiska modellen ingick vattenledningsrör där buljong och bakterier växt i inkubationsskåp i 30 °C i 5 dagar för att sedan stå i rumstemperatur i ytterligare 5 dagar med daglig skakning i en timme, samt att buljong byttes ut vid dag 5 och nya bakterier tillsattes dag 7.

    Keywords : Norway spruce bark; bark biorefinery; extractives; cellulose; lignin; non-cellulose; polysaccharides; soxhlet extraction; hot-water extraction; organosolv extraction; PAA; delignification; carbohydrate analysis; 2D HSQC-NMR and FTIR; Granbark; bark bioraffinaderi; lignin; organosolv extraktion; hot-water extraktion;

    Abstract : Spruce Bark contains several fundamental main substances; lignin, non-cellulose polysaccharides, cellulose and extractives. This undergraduate study focuses on developing a process to extract each of these components from spruce bark using a biorefinery concept, with a main focus on extracting lignin without degradation.

  5. 4. Microbial test organisms for sterilization processes in food industry

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

    Author : Yasmin Nabila; [2018]
    Keywords : Aseptic processing and packaging; validation; test organisms; Aspergillus brasiliensis; Bacillus atrophaeus; Bacillus subtilis; sterilization; disinfection; applied microbiology; teknisk mikrobiologi; Technology and Engineering; Agriculture and Food Sciences;

    Abstract : The importance of sterilization processes has been a major topic in the food manufacturing industry since it preserves the quality and provides longer shelf-life by preventing microbiological recontamination of products. Aseptic packaging is an alternative technique to pack commercially sterile products into containers with a very low recontamination rate, thus, the entire production chain must be designed according to the aseptic condition, including the packaging material, the filling machines, and the surrounding area where the process takes place.

  6. 5. Evaluation of Esterification as a Valorization Route for Oxidized Lignin

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Johanna Lindmark; [2017]
    Keywords : Lignin; Kraft Lignin; Esterification; Peracetic Acid; Oxidized Lignin; Muconic Acid; Vanillic Acid;

    Abstract : RISE Bioeconomy is working with the biorefinery concept. That is, for the company, to utilize all wood derivatives in effective processes, resulting in unique products. RISE Bioeconomy is investigating the possibilities of producing holocellulose through an oxidative delignification process of wood, using peracetic acid (PAA). READ MORE
