The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Spirulina (Arthrospira platensis) priming mitigates cadmium stress in pearl millet (Pennisetum glaucum) by enhancing photosystem efficiency

BMC Plant Biology
Cadmium (Cd) is a highly toxic pollutant that impairs plant growth and photosynthetic performance. While seed priming with Spirulina (Arthrospira platensis) can enhance stress tolerance, its specific role in protecting the photosynthetic machinery from ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Impact of biofilm support media on microbial dynamics, rocket (Eruca vesicaria subsp. sativa) growth, and antioxidative content in aquaponics

BMC Plant Biology
Aquaponics integrates aquaculture and hydroponics into a recirculating system where fish-derived nutrients sustain plant growth. The efficiency of this process relies heavily on the biofilm support media that facilitate microbial activity and nutrient ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
