PCC 6803 (cyanobacterium) was created by means of DNA recombination. In its genome, ORF469, the key DNA fragment controlling the light-independent pathway of chlorophyll biosynthesis was deleted and replaced by erythromycin resistance cassette. The operation resulted in the fact that the content of chlorophyll in mutant cells was fully controlled by illumination and two kinds of cells were harvested, one is high chlorophyll with concentration of 9.427 μg · mg-1 and the other is low chlorophyll with concentration of 0.695 μg ·mg-1. They were subjected to thermal simulation respectively at 300℃ for 100 h. The alkanes biomarkers from pyrolysates were analyzed by GC-MS and main difference between high and low chlorophyll cells was found at their contents of isoprenoid hydrocarbons. Pr/nC17 and Ph/nC18 from pyrolysate of low chlorophyll cells were 0.192 and 0.216 respectively, which were about 1/3 and 1/7 of that from high chlorophyll cells. The展开更多
