| Abstract: | Cells of Nostoc muscorum and Rhodopseudomonas spherodes have been subjected to thermal alteration over varying periods of time. Experiments were conducted using both unextracted and extracted cells in the absence and presence of montmorillonite. The isoprenoid hydrocarbons produced in these experiments have been examined. The major hydrocarbons produced were phytane and five isomeric phytenes. Phytane was observed to form faster from the unextracted cells than from the extracted cells. Montmorillonite increased the amount of phytane formed from the unextracted cells of Nostoc muscorum but not from the cells of Rhodopseudomonas spheroides. No phytadienes, pristane or pristenes were detected in the products of any of these experiments. |
