Halophiles and Halotolerants: From Industry to Astrobiology

by Keith CowingOctober 4, 2025October 4, 2025

Halophilic and halotolerant microorganisms, as members of the extremophile group, hold significant potential for both industrial applications and astrobiological research.

Micrographs of fresh (a) and 6 day old (b) SD1T cells stained with acridine orange at 1000x magnification (500 nm Ex./526 nm Em.). Bright spots (a) were common among cells. Terminal spores shown in panel B were common in older or nutrient-limited cultures. Scale bars are 5 µm. -- International Journal of Systematic and Evolutionary Microbiology via PubMed

Dethiothermospora halolimnae gen. nov., sp. nov., A Novel Moderately Halophilic, Thermotolerant, Bacterium Isolated From A Brine Lake

by Keith CowingMay 4, 2025May 4, 2025

A novel, strictly anaerobic, slightly alkaliphilic, halotolerant, peptide- and amino acid-utilizing bacterial strain, SD1T, was isolated from a hypersaline lake in Western Australia.
