Ethanol production by thermophilic bacteria: metabolic control of end product formation in Thermoanaerobium brockii.

abstract：:From the cell envelope preparation of Sphingomonas paucimobilis two membrane fractions with different densities were separated by sucrose density gradient ultracentrifugation. The high-density fraction contained several major proteins, phospholipids, and glycosphingolipids, which are the only glycolipids of this lipop...
