1. 6. The Production and Characteristics of an Orange Fleshed Sweet Potato Yogurt

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

   Author : Ariam Kunfu; [2023]
   Keywords : Sweet potato; fermentation; Ghana; yogurt; L. bulgaricus; S. thermophilus; food technology and nutrition; Agriculture and Food Sciences;

   Abstract : Yogurt is an ancient food, used for a better preservation of milk. Milk gets fermented by Streptococcus thermophilicus and Lactobacillus bulgaricus (lactic acid bacteria, LAB) which converts the lactose present in the milk to lactic acid. These probiotics support the microbial population balance of the gastrointestinal tract. READ MORE

3. 7. Activity and stability of urease enzyme molecules for on-site urea measurement in milk

   University essay from Linköpings universitet/Sensor- och aktuatorsystem

   Author : Emma Valtersson; [2022]
   Keywords : Kemisk biologi; urea i mjölk; biosensor;

   Abstract : The nitrogenous metabolite urea is an important biomarker that indicates cows’ nutritional intake. Today, determining the urea concentration from milk samples requires analysis techniques in a lab which is time-consuming and expensive. READ MORE

4. 8. 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

5. 9. Flow of non-starter lactic acid bacteria : from to silage to raw milk to cheese

   University essay from SLU/Department of Molecular Sciences

   Author : John Johansson; [2022]
   Keywords : Non-starter lactic acid bacteria; herbage; silage; raw milk; cheese; Lactiplantibacillus plantarum; Lacticaseibacillus paracasei; Lacticaseibacillus casei;

   Abstract : Modern cheese manufacturing uses a known starter culture of lactic acid bacteria (SLAB) for the fermentation of lactose to lactic acid. There is, however, often a second fermentation in cheese manufacturing by non-starter lactic acid bacteria (NSLAB). READ MORE

6. 10. Comparing different methods of measuring particle size for pharmaceutical excipients

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

   Author : Jiawen Wang; [2022]
   Keywords : particle size; comparison; Malvern analysis; Qicpic analysis; Pharmaceutical technology; Technology and Engineering;

   Abstract : In pharmaceutical science, particle size is one of the most fundamental parameters of materials, but different particle-sizing analysis methods lack a uniform standard for measuring irregular particle size, making it difficult to compare the accuracy and applicability of different particle-sizing analysis methods. Experiments on excipients used in pharmaceuticals are carried out in this paper by laser diffraction analysis (Malvern wet and dry), dynamic image analysis (Qicpic), and microscopic methods (Qicpic, SEM, and light microscopy) to determine the applicability and limitations of each method, as well as to clarify their advantages and disadvantages.
