1. 21. Co-occurence and co-metabolism of phototrophic and heterotrophic microbial communities in the Baltic Sea

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Cátia Ifigénia Corujo Chaves; [2017]
   Keywords : microbiology; extracelullar enzymatic activity; amplicon sequencing; 16S and 18S sequencing;

   Abstract : In the marine water column, microbial autotrophs and heterotrophs coexist forming the beginning of the food chain which sustains the whole biological system. Both groups play a vital role in the microbial loop. READ MORE

3. 22. Inhibiting malate metabolism in L. plantarum 299v by introducing lactic acid in ProViva apple drinks

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Madeleine Göransson; [2016]
   Keywords : Microbiology; Product development; Lactic acid; Lactobacillus plantarum 299v; ProViva Apple drink; Preservative; food technology; livsmedelsteknologi; Technology and Engineering;

   Abstract : This master thesis aimed to evaluate the possibilities of inhibition of Lactobacillus plantarum 299v metabolism of malate by introduction of lactic acid in ProViva apple drinks. The malate metabolism of L. READ MORE

4. 23. Biopreservation effects with Wickerhamomyces anomalus after 2 months moist airtight storage of sorghum

   University essay from SLU/Dept. of Microbiology

   Author : Louise Nybogård; [2016]
   Keywords : wickerhamomyces anomalus; sorghum; storage; biocontrol; biopreservation; food loss;

   Abstract : Today one third of all produced food is thrown away and one reason for this is microbial spoilage. Hunger and malnutrition in Africa could be reduced if the food loss is reduced. Wickerhamomyces anomalus is a possible biocontrol agent in food science that has shown antifungal and antibacterial effects on, for example, stored barley. READ MORE

5. 24. The effects of trace elements on the microbial communities of thermophilic biogas production

   University essay from SLU/Dept. of Microbiology

   Author : Robin Hagblom; [2016]
   Keywords : biogas; thermophilic; trace elements; ammonia; SAO; fhs;

   Abstract : The increasing need for alternatives to fossil fuels and traditional waste management systems can be simultaneously addressed by the production of biogas using organic waste as input material. The biogas produced can be used directly for energy production or upgraded to increase methane purity for use in the engines of motor vehicles. READ MORE

6. 25. Weak acids’ microbial and sensorial effect on marinated herring

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

   Author : Jennika Larsson; [2016]
   Keywords : sensorial test; Lactobacillus plantarum; acetic acid; malic acid; citric acid; Marinated herring; lactic acid; applied microbiology; teknisk mikrobiologi; MRS; accelerated test; Technology and Engineering; Agriculture and Food Sciences;

   Abstract : Marinated herring is a food product usually with a sauce containing acetic acid. In this project the weak acids malic acid, citric acid, and lactic acid were evaluated for use in the sauce for marinated herring instead of using acetic acid. The microbial and sensorial effects of the acids were evaluated. READ MORE
