| Formation of Hydrocarbons by Photobleaching Cyanobacterium, A nacystis nidulans  | | | | Abstract
| The cyanobacterium Anacystis nidulans is bleached when subjected to both light and 0 2 to gether with suitable (pre)treatment o f the cells such as incubation at high (^ 4 8 °C) or low (S 17 °C) temperatures, or in presence o f metabolic inhibitors, or o f substances forming com plexes with divalent cations. Concomitantly degradation o f the intracellular membranes is ob served (G. Schmetterer, G. A. Peschek, Biochem. Physiol. Pflanzen 176, 9 0 —100 (1981)). The same three conditions cause formation o f hydrocarbons, mostly ethane, a characteristic product of lipid peroxidation. Ethane production is unchanged and still light-sensitive even when no more pigments can be detected in the cells. In "white" cells light-dependent 0 2-uptake is also observed. The action spectrum of this process suggests that "completely" bleached cells retain very small amounts of residual chlorophyll, which must be unusually resistant to photooxidation. | | | |
