1. 16. Characterisation of free and conjugated protease inhibitors from Solanum tuberosum

   University essay from Uppsala universitet/Institutionen för kemi - BMC

   Author : Kristoffer Lundmark; [2017]
   Keywords : enzyme; trypsin; chymotrypsin; pancrease protease; serine protease inhibitors; SPI; potato tubers; potato; Solanum tuberosum; immobilized; aluminium oxide membranes; inhibitor-enzyme interaction;

   Abstract : The main purpose of the master thesis project is to investigate the influence of selected serine protease inhibitors (SPI) on the catalytic action of the serine proteases chymotrypsin and trypsin, in a conjugated and non-conjugated state. The inhibitors included for this study were extracted from Solanum tuberosum, i.e.common potato. READ MORE

3. 17. Inactivation of the urease enzyme by heat and alkaline pH treatment : retaining urea-nitrogen in urine for fertilizer use

   University essay from SLU/Dept. of Energy and Technology

   Author : Magdalena Geinzer; [2017]
   Keywords : fertilizer; nutrient recycling; source separated urine; urea; urease; urine drying;

   Abstract : Urine, containing nitrogen (N) in the valuable form of urea, has a high fertilizer potential if it is dehydrated and the nutrients are concentrated. However, urea is not only a valuable N source for plants but also for microbiota which possess a highly efficient urease enzyme to degrade urea into volatile ammonia (NH3). READ MORE

4. 18. The regulatory effect of CsrA on cstA, glgCAP and flhDC in an RNase P ts mutant Escherichia coli

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Zeinalabedin Hilow; [2017]
   Keywords : CsrA; CsrB; CsrC; CsrD; GlgCAP; FlhDC; CstA; E. Coli; Glolbal regulator; RNase P; C5; ts; wt;

   Abstract : CsrA is a global post-transcriptional regulatory protein that has a great impact on many physiological pathways in a cell. It regulates central carbon metabolism, motility and biofilm formation as well as virulence, pathogenesis, quorum sensing and the oxidative stress response. READ MORE

   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

6. 20. The effect of mechanical shear in ambient yoghurt

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

   Author : Emilia Magdaleno Morales Henrysson; [2016]
   Keywords : long life yoghurt; stabilizers; viscosity; Yogurt; shear rate; food technology; livsmedelsteknologi; Technology and Engineering; Agriculture and Food Sciences;

   Abstract : Yoghurt is a fermented product form the milk, well known in the world. The fermentation is carried out by Lactic acid bacteria (LAB). The most common are Streptococcus thermophilus and lactobacillus bulgaricus, these bacteria make the milk acid, generating a disturbance in the casein micelles making a solid mass called coagulum.
