  2. 6. Influence of Lactic Acid Fermentation on Enteropathogenic Bacteria. Growth Inhibition in Cereal Gruels and in Human Intestine

    Author : Rose Kingamkono; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; intestinal mucosal permeability; enteropathogenic bacteria; enterotoxins; lactic acid fermentation;

    Abstract : Togwa, a lactic-fermented cereal gruel, is widely consumed in Tanzania as a soft drink or used as a complementary food for young children. Studies were conducted to evaluate the potential of togwa to inhibit growth of common enteropathogenic bacteria and heat-labile (LT) enterotoxin production. READ MORE

  4. 7. Fermented probiotic beverage based on quinoa : Functionality, hygiene, and health effects

    Author : Pamela Rosario Canaviri Paz; Avdelningen för livsmedel och läkemedel; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Quinoa grains; Fermentation; Lactic acid bacteria; Probiotics; Food safety; Starter culture; Polyphenol compounds; Microbiota composition; Functional food; Gut microbiota;

    Abstract : White quinoa grains were used as a source of novel beneficial microorganisms and as a matrix for development of a fermented plant-based drink. Studies on the quinoa grain microbiota were performed by applying spontaneous fermentation to allow isolation of autochthonous Lactiplantibacillus strains with potential to be used as starter cultures.

  5. 8. Industrial challenges in the use of Saccharomyces cerevisiae for ethanolic fermentation of lignocellulosic biomass

    Author : Violeta Sanchez Nogue; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Saccharomyces cerevisiae; Pentose fermentation; Evolutionary engineering; Acetic acid; pH; Short-term adaptation; Resident yeast; Spent sulphite liquor fermentation; Dekkera bruxellensis; Lactobacillus pentosus.;

    Abstract : The sustainable production of ethanol from lignocellulosic biomass requires the combination of efficient hydrolysis and complete fermentation of all the monomeric sugars present in the raw material. The present work was aimed at tackling some of the major challenges that will be encountered in commercial-scale ethanol production using Baker’s yeast, Saccharomyces cerevisiae, the preferred microorganism for the fermentation step.

  6. 9. Modelling and Optimisation of Integrated Biotechnical Processes -Application to the Fermentative Production of Lactic Acid from Wheat Flour

    Author : Christina Åkerberg; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; economy; wheat flour; starch; lactic acid; kinetics; simulation; modelling; optimisation; Kemiteknik och kemisk teknologi;

    Abstract : Biotechnical processes are often integrated to increase productivity and yield. It is difficult to predict the effects of process integration and to find optimum conditions for the process. A valuable tool for the evaluation of a complete process is mathematical modelling. READ MORE

  7. 10. Development of the Steam Pretreatment Process for Production of Ethanol from Lignocellulosic Biomass

    Author : Sanam Monavari; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spruce; Ethanol production; Sugarcane bagasse; SSF; Fermentation; Enzymatic hydrolysis; SO2; Steam pretreatment; Acid catalyst;

    Abstract : At a time when natural petroleum resources are on the verge of depletion, and concern about climate change is increasing, the potential of lignocellulosic material for the production of bioethanol is well recognized. Ethanol can be produced from biomass through enzymatic hydrolysis and fermentation. READ MORE
