Photosynthetic cyanobacteria as future biotechnological hosts; considerations in regards to metabolite toxicity and cofactor redox balance
(Turun yliopisto, 2018-11-02)
There is an increasing global need for developing new sustainable alternatives and technological solutions for replacing oil‐based products currently in use. In response to this demand, photosynthetic cyanobacteria have ...
Dynamic regulation of photosynthesis by chloroplast thioredoxin systems
(Turun yliopisto, 2018-08-08)
Oxygenic photosynthesis is sunlight-energized conversion of CO2 into
carbohydrates using electrons extracted from water. It occurs in
cyanobacteria and in their endosymbiotic evolutionary descendants, the
chloroplasts ...
Composition and phosphorylation-dependent functional interactions of thylakoid protein complexes in Arabidopsis
(Turun yliopisto, 2018-06-15)
In higher plants the thylakoid embedded pigment-protein complexes, photosystem (PS) I and PSII together with their respective light harvesting complex (LHC) antennas work in series to harvest solar energy and convert it ...
Developing synthetic biology strategies for enhancing the efficiency of engineered cyanobacterial expression systems
(Turun yliopisto, 2020-05-08)
Cyanobacteria are unique prokaryotic microbes performing oxygenic photosynthesis. They have inherent capacity of the direct conversion of solar energy, CO2 and water into carbonbased compounds. Scientists’ increasing ...
Molecular approaches for mycotoxin risk reduction
(Turun yliopisto, 2019-06-10)
Mycotoxin contamination in food is a serious concern for human and animal health. Today, we do not know how to detoxify food materials that are contaminated with mycotoxins in ways that retain their edibility. Therefore, ...
SNF1-related protein kinases : activation, responses to osmotic stress, and cuticle formation
(Turun yliopisto, 2019-09-06)
Plants regulate their responses to changing environmental conditions to cope with stresses and survive under natural growth habitats. Growth and stress responses must be strictly balanced to prevent poor survival and ...
The biological role of omega subunit of cyanobacterial RNA polymerase
(Turun yliopisto, 2020-08-18)
ABSTRACT
Cyanobacteria are important primary producers performing oxygenic photosynthesis using CO2 or HCO3- as a carbon source. Active adjustment of gene expression according to environmental cues depends on the RNA ...
Wastewater treatment with algae
(Turun yliopisto, 2020-06-16)
Microalgae have been under investigation as alternatives for wastewater treatment for the last 60 years. However, we are yet to see an algal based process to be trusted as a treatment strategy on a large scale. At present, ...
Evaluating the possibilities and limitations of cyanobacterial hosts for future biotechnological applications
(Turun yliopisto, 2020-06-26)
Carbon neutral solutions and circular economy are a relevant part of a sustainable future. Solutions based on photosynthetic cyanobacteria have potential due to several facts: i) Cyanobacteria can produce target compounds ...
On singlet oxygen, photoinhibition, plastoquinone, and their interconnections
(Turun yliopisto, 2020-12-18)
In oxygenic photosynthesis light is captured in series by two protein complexes: photosystem II and photosystem I (PSI and PSII). Electron transfer from PSII to PSI is mediated by the plastoquinone (PQ) pool. Despite being ...
