Impacts of elevated CO2 concentration on biochemical composition, carbonic anhydrase, and nitrate reductase activity of freshwater green algae

, 2005
To investigate the biochemical response of freshwater green algae to elevated CO2 concentrations, Chlorella pyrenoidosa Chick and Chlamydomonas reinhardtii Dang cells were cultured at different CO2 concentrations within the range 3-186 μ mol/L and the ...

Species Dynamics and Gene Expression in Algal Polycultures Under Mixotrophic Cultivation in Outdoor Pilot‐Scale Nordic Conditions

Biotechnology and Bioengineering, EarlyView.
These results demonstrate that mixotrophic conditions drive both microbial community shifts and metabolic reprogramming, underscoring the importance of cultivation strategy and polyculture selection for targeted applications such as nutrient recovery and bioproduct generation.

Combinatorial Metabolic Engineering of Alkane Biosynthesis in the Osmotolerant Yeast Debaryomyces hansenii CBS 767

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Debaryomyces hansenii is a yeast with diverse potential applications like producing oleochemicals from biomass. Yet, combinatorial metabolic engineering in D. hansenii is limited because, like many nonconventional organisms, key genomic data and genetic elements are missing. Here, we report phenotypic characterization, genomic integration loci,

Nitrate reductase and glutamine synthetase activities, nitrate and ammonia assimilation, in the unicellular alga Cyanidium caldarium

, 1981
Nitrogen-limited continuous cultures of Cyanidium caldarium contained induced levels of glutamine synthetase and nitrate reductase when either nitrate or ammonia was the sole nitrogen source. Nitrate reductase occurred in a catalytically active form.

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

BMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

A narrow bandgap Schottky heterojunction Fe2N/CeO2 microneedle triggering sonodynamic reactive oxygen species storm for drug‐resistance‐free skin fungal infection

BMEMat, EarlyView.
Inorganic sonosensitizers suffer from inefficient electron‐hole separation, rapid recombination, and wide bandgaps in anti‐fungal applications. We propose MN@Fe2N/CeO2 to directly eliminate fungi without drug resistance. Combining semiconductor CeO2's advantages with Fe2N's high work function and activity enables efficient Schottky heterojunctions ...

Influence of nitrate-containing arugula juice on nitrate-reducing oral bacteria and periodontopathogens in smokers’ biofilm

Frontiers in Dental Medicine
Green leafy vegetables such as arugula are rich in nitrates that support oral health, yet their effects on oral microbial balance, especially in smokers, remain unclear.
