Detection of a Planktothrix agardhii Bloom in Portuguese Marine Coastal Waters [PDF]

open access: yesToxins, 2017
Cyanobacteria blooms are frequent in freshwaters and are responsible for water quality deterioration and human intoxication. Although, not a new phenomenon, concern exists on the increasing persistence, scale, and toxicity of these blooms.

Yeasts Killer/Sensitivity Phenotypes and Halotolerance [PDF]

open access: green, 2000
Yeast killer phenotype is not uniformly distributed within certain genera or even within some species. Salt has been described as enhancing killer action, especially in strains that have been isolated from salt environments.

Extreme Osmotolerance and Halotolerance in Food-Relevant Yeasts and the Role of Glycerol-Dependent Cell Individuality [PDF]

open access: goldFrontiers in Microbiology, 2019
Osmotolerance or halotolerance are used to describe resistance to sugars and salt, or only salt, respectively. Here, a comprehensive screen of more than 600 different yeast isolates revealed that osmosensitive species were equally affected by NaCl and ...

Deletion or overexpression of tpx gene alters doubling time and response to stress agents and affects asphaltene biotransformation in Micrococcus sp. IITD107 [PDF]

open access: yesApplied Microbiology and Biotechnology
Thiol peroxidases have been identified as antioxidant enzymes in different organisms. However, there have been only a few reports on deleting or overexpressing its gene to characterize its function.
