1. Machine learning-assisted image analysis and metabarcoding for monitoring of plankton in the seas surrounding Sweden
Master-uppsats, KTH/Industriell bioteknologiSammanfattning : I miljöövervakningen av haven runt Sverige har manuell mikroskopi av plankton länge varit den huvudsakliga tekniken för att övervaka växtplanktonbestånden och algblomningar. Nya tekniker utvärderas, men det är inte känt hur resultaten från de nyare teknikerna relaterar till varandra. LÄS MER
2. Diatoms from the late Holocene of the western Chukchi Sea, Arctic Ocean: environmental signals and palaeoceanography
Master-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaperSammanfattning : The sediment Core SWERUS-L2-2-PC1 (2PC) retrieved from the Chukchi Sea, Arctic Ocean sits in an oceanographically dynamic location at the Arctic-Pacific Ocean gateway. The 8.3 m-long core was retrieved in Herald Canyon at the marginal ice zone at 57 m depth. LÄS MER
3. Ensjön under 200 år : En stratigrafisk studie om vad bevarade kiselalger i sediment kan berätta om klimat och markanvändning
Kandidat-uppsats, Södertörns högskola/Institutionen för naturvetenskap, miljö och teknikSammanfattning : Since 1750, human emissions of greenhouse gases have created a temperature increase, affecting the whole world. Diatoms, single-celled microscopic algae that lives in waters all over the world, have different environmental preferences such as the water depth at which the thrive, salinity, nutrients, pH-values and more.

4. Uttrycksmönster av kiseltransportörgener hos Chaetoceros affinis med realtids-PCR
Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)Sammanfattning : Diatoms are photosynthetic protists that reside in aquatic environments. A unique feature of diatoms is their cell wall structure made of silica. Silicon is a limiting nutrient for diatoms. The bioavailable form of silicon in aquatic environments is silicic acid. LÄS MER
5. Phaeodactylum tricornutum – Compositional Analysis, Carbohydrate-Active Enzymes and Potential Applications of Residual Algal Biomass from Omega 3 Production
Master-uppsats, KTH/Industriell bioteknologiSammanfattning : Microalgae are gaining more attention for several reasons such as being potential producers of sustainable fuel, for use as health supplements and in skincare. Simris Alg is a Swedish company that produces Omega 3 supplements from a primary producer of these fatty acids - the algal diatom Phaeodactylum tricornutum, which is a sustainable alternative to Omega 3 derived from fish.
