Cyanobacterial Extracellular Vesicles as Protein Carriers: Towards Fish Vaccination. [PDF]
Microb BiotechnolHere, we describe that Synechocystis EVs are stable nanostructures that can induce specific immune responses in fish with additional adjuvant features. It represents a biotechnological breakthrough towards a novel antigen‐carrier platform for sustainable fish‐pathogen control in aquaculture settings. ABSTRACT Fish aquaculture faces significant economic

Cultivation in a Natural Microbial Community Enhances the Industrial Performance of a Genetically Engineered Cyanobacterium for Bioplastic Production. [PDF]
Microb BiotechnolWe developed a hybrid photosynthetic microbiome, in which the native cyanobacterium of a natural microbial consortium was replaced with a genetically engineered Synechocystis strain optimised for polyhydroxybutyrate (PHB) production. The hybrid system demonstrated improved tolerance to abiotic stresses, making it suitable for upscaling.

Differences in photosystem II activity and carbon allocation during photomixotrophic growth in distinct wild-type strains of Synechocystis sp. PCC 6803. [PDF]
Plant JSUMMARY The regulation of photosynthetic electron transport during photomixotrophic growth in cyanobacteria remains incompletely understood. In this study, we characterized four wild‐type strains (WT 1–4) of Synechocystis sp. PCC 6803 and observed distinct strain‐specific differences in photosystem II (PSII) function under photomixotrophic conditions ...

High intrinsic hydrolytic activity of cyanobacterial RNA polymerase compensates for the absence of transcription proofreading factors [PDF]
, 2020 The vast majority of organisms possess transcription elongation factors, the functionally similar bacterial Gre and eukaryotic/archaeal TFIIS/TFS. Their main cellular functions are to proofread errors of transcription and to restart elongation via ...

Engineering Nitrogen Fixation Activity in an Oxygenic Phototroph
mBio, 2018 Biological nitrogen fixation is catalyzed by nitrogenase, a complex metalloenzyme found only in prokaryotes. N2 fixation is energetically highly expensive, and an energy-generating process such as photosynthesis can meet the energy demand of N2 fixation.
