What is Bacterial Growth at -15°C in Permafrost about?
Planococcus halocryophilus Or1, a bacterium isolated from Canadian high Arctic permafrost, is able to grow and divide at an unprecedented low temperature of -15°C, and remains metabolically active down to -25°C. To understand its cold adaptation, the authors investigated its genome, cell physiology, and transcriptomes under cold (-15°C) and high salt (18% NaCl) conditions. They found unusual cell envelope features and membrane remodeling favoring saturated fatty acids. Genomic analyses revealed multiple cop
