While the recession of glaciers in Antarctic is global concern under climate change, impact deglaciation on soil microbiomes still limited. Here, samples were collected from permafrost (P), moraine (M) and Deschampsia antarctica rhizosphere (R) soils near Ecology Glacier (Antarctic), their physicochemical properties microbial communities (bacteria, archaea fungi) characterized. Our analyses showed that there significant differences between R P M samples. Specifically, amplicon sequencing 16S rDNA revealed high bacterial richness diversity studied soils, which dominated mainly by phyla Proteobacteria, Actinobacteriota Bacteroidota. In contrast, lower observed archaeal communities, Chenarchaeota (M R) Thermoplasmadota (M). addition, fungal community analysis a R), phylum Ascomycota. observations are consistent with previous reports describing relevant changes during glacial recession, including fewer groups (archaea fungi). However, further studies needed to elucidate contributions formation plant colonization ice-free Antarctica change.

Advanced Optimization of Bioprocess Parameters for Exopolysaccharides Synthesis in Extremophiles

Processes, Journal Year: 2025, Volume and Issue: 13(3), P. 822 - 822

Published: March 11, 2025

Exopolysaccharides (EPSs) represent versatile biopolymers finding diverse applications in food, pharmaceuticals, and bioremediation industries. Extremophiles, thriving under extreme environmental conditions, have emerged as a promising source of novel EPSs with better stability bioactivity. The present work reviews the complex influence various abiotic factors bioprocess parameters such temperature, pH, carbon nitrogen sources, C/N ratios, oxygen transfer dynamics on production from extremophilic microorganisms. Results underline important role temperature for structural functional properties EPSs, synthesis cryoprotective polymers psychrophiles to thermostable thermophiles cold stress. pH has an extensive effect enzymatic activities: optimal neutral slightly acidic conditions exist most strains. Carbon sources determine not only yield but also its features, while ratios regulate balance between biomass polymer biosynthesis. Besides that, limitations—which may happen particularly viscous or saline media—are overtaken by optimized bioreactor configuration stirring strategies. These findings are highly relevant development tailored cultivation enabling maximization EPS yields adaptation comply industrial requirements. This study provides framework enhancing leveraging adaptive traits extremophiles. approach supports sustainable use biopolymers, advances fermentation processes, helps uncover underlying mechanisms involved.

Unveiling the structure-emulsifying function relationship of truncated recombinant forms of the SA01-OmpA protein opens up a new vista in bioemulsifiers

Microbiology Spectrum, Journal Year: 2024, Volume and Issue: 12(2)

Published: Jan. 11, 2024

The emulsifying ability of SA01-OmpA (outer membrane protein A from Acinetobacter sp. SA01) was found to be constrained by challenges like low production efficiency and high costs associated with recovery E. coli inclusion bodies, as described in our previous study. present study sought benefit the advantages targeted truncating protein, taking into account reduced propensity expression bodies cytotoxicity. Here, structure activity relationship two truncated recombinant forms unraveled through a hybrid approach based on experimental data computational methodologies, representing an innovative bioemulsifier advantageous activity. variants were cloned heterologously expressed host cells subsequently purified. results showed increased N-terminally (NT-OmpA) compared full-length SA01-OmpA. Molecular dynamics (MD) simulations analysis demonstrated direct correlation between C-terminally (CT-OmpA) its bodies. Analysis structure-activity revealed that, deletion β-barrel portion N-terminal NT-OmpA while lowering Contrary not cytotoxic, according MTT assay, FCM analysis, AO/EB staining. findings this extensive advance knowledge at molecular level well design development efficient bioemulsifiers.IMPORTANCEPrevious research (Shahryari et al. 2021, mSystems 6: e01175-20) introduced characterized multifaceted variety functions, including maintaining cellular homeostasis under oxidative stress conditions, biofilm formation, outer vesicles (OMV) biogenesis, beneficial capacity. By current presents unique method for developing protein-type bioemulsifiers. indicate that has potential fully replace novel significant This opens up new frontier bioemulsifiers, shedding light possible forms.
