    Sammanfattning : 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. LÄS MER

  3. 2. Microbial test organisms for sterilization processes in food industry

    Master-uppsats, Lunds universitet/Bioteknik; Lunds universitet/Teknisk mikrobiologi

    Författare :Yasmin Nabila; [2018]
    Nyckelord :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;

    Sammanfattning : 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.

  4. 3. Evaluation of Esterification as a Valorization Route for Oxidized Lignin

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Industriell miljö- och processteknik

    Författare :Johanna Lindmark; [2017]
    Nyckelord :Lignin; Kraft Lignin; Esterification; Peracetic Acid; Oxidized Lignin; Muconic Acid; Vanillic Acid;

    Sammanfattning : 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). LÄS MER

  5. 4. Preventing Microbial Growth on pall-rings when upgrading biogas using absorption with water wash

    Magister-uppsats, Tema vatten i natur och samhälle

    Författare :Anna Håkansson; [2006]
    Nyckelord :Biogas; upgrading; water absorption; microbial growth; water treatment; peracetic acid; UV-light;

    Sammanfattning : For produced biogas to be usable as vehicle fuel it has to be upgraded to a higher energy content. This is accomplished by elevation of the methane concentration through removal of carbon dioxide. Absorption with water wash is the most common upgrading method used in Sweden today. LÄS MER
