1. 1. SOIL GROSS NITROGEN MINERALISATION AND FOREST GROWTH IN FOUR HEMIBOREAL FOREST STANDS IN SOUTHWEST SWEDEN

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Linnéa Eriksson; [2023-04-20]
   Keywords : soil C:N; forest production; 15N isotope dilution; gross N mineralisation; ammonium; soil carbon; soil nitrogen; root exudates; stoichiometric decomposition; boreal forests; priming; microbial C limitation;

   Abstract : Boreal and temperate forests together make up the largest terrestrial net C sink in the world. They take up carbon dioxide (CO2) from the atmosphere and store it in plant biomass and soil as they grow, making them crucial in mitigating global climate change. READ MORE

3. 2. Method development of flow cytometry analysis of yeast and lactic acid bacteria viability for alcohol fermentation

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

   Author : Megha Komahan; [2023]
   Keywords : Flow cytometry; yeast; lactic acid bacteria; fermentation; cell viability; applied microbiology; Technology and Engineering;

   Abstract : The usage of yeast in conventional brewing techniques involving alcoholic fermentation is an age-old process. Analyzing the viability and obtaining physiological information regarding the microbial diversity of the fermentation samples plays a pivotal role in obtaining real-time information as well as developing a more efficient process design.

4. 3. Effects of recirculating water treatment sludge

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Sofia Mile; [2023]
   Keywords : Chemical Engineering; Water and Environmental Engineering; Water Treatment; Coagulation Flocculation; Sludge Recirculation; Technology and Engineering;

   Abstract : Drinking water is crucial in our everyday life. As with many other processes, it is important to produce water of drinking quality in a sustainable manner. This can occur by e.g. READ MORE

5. 4. The potential nitrous oxide emissions in a permanent grassland chronosequence

   University essay from SLU/Dept. of Forest Mycology and Plant Pathology

   Author : Sandra Lillsjö Kronblad; [2023]
   Keywords : nitrous oxide emission; permanent grasslands; denitrification; nitrous; reen house gas; agriculture;

   Abstract : As a part of a larger project (Belowground biodiversity of grasslands – conservation needs and potential to promote sustainable agriculture), this study aims to investigate potential nitrous oxide (N2O) emissions and microbial gene abundances needed for the production (nirS and nirK) and reduction (nosZI and nosZII) of nitrous oxide in soil of permanent grasslands of various age. Thegrasslands have at different times been converted to permanent grasslands and are of interest because of the possibility to shed more light about the passage of time’s affects on the soil microbialcommunities and their activity.

6. 5. Review of pH recommendations for soilless cultivation systems

   University essay from SLU/Dept. of Crop Production Ecology

   Author : Elric Fabricius; [2023]
   Keywords : soilless cultivation; hydroponics; aeroponics; NFT; nutrient film technique; DWC; deep water culture; pH; nutrient solution; speciation; availability; biomass production;

   Abstract : Our human population is growing, and with that, so is our demand for food, food that today still is not a guarantee for all of us. To help increase global food security, the diversification of our food production through the implementation of soilless, hydroponic cultivation systems has been suggested. READ MORE
