Explorative characterization and taxonomy‐aligned comparison of alterations in lipids and other biomolecules in Antarctic bacteria grown at different temperatures
Abstract Temperature significantly impacts bacterial physiology, metabolism and cell chemistry. In this study, we analysed lipids and the total cellular biochemical profile of 74 fast‐growing Antarctic bacteria grown at different temperatures. Fatty acid diversity and temperature‐induced alterations...
