Jeff Fox, Current Topics and Features Editor of Microbe Magazine, talks with Harald Huber of the Johann Wolfgang Goethe University in Frankfurt, Germany. Huber and his collaborators have looked at the archaeon Ignicoccus hospitalis and found a very unusual cellular envelope architecture, unique among archaea and unlike that of any known bacterium. Among other findings, I. hospitalis generates ATP within the periplasm, and the ATP flows inward towards the cytoplasmic membrane.
