Survival dynamics of cystic fibrosis-related Gram-negative bacterial pathogens (Pseudomonas aeruginosa and Burkholderia cenocepacia) in Dead Sea and Atlantic Ocean waters.

Clinical cystic fibrosis (CF) Pseudomonas aeruginosa (n=6) and Burkholderia cenocepacia (n=4) were inoculated in marine brines from the Dead Sea and the Atlantic Ocean and their survival was monitored over a 1 month duration. In Dead Sea samples, all P. aeruginosa and B.

Genomic adaptations of the halophilic Dead Sea filamentous fungus Eurotium rubrum.

The Dead Sea is one of the most hypersaline habitats on Earth. The fungus Eurotium rubrum (Eurotiomycetes) is among the few species able to survive there. Here we highlight its adaptive strategies, based on genome analysis and transcriptome profiling.

Evolution of genomic diversity and sex at extreme environments: fungal life under hypersaline Dead Sea stress.

We have found that genomic diversity is generally positively correlated with abiotic and biotic stress levels (1-3). However, beyond a high-threshold level of stress, the diversity declines to a few adapted genotypes. The Dead Sea is the harshest planetary hypersaline environment (340 g.
