| As steroid biosynthesis requires molecular oxygen, fossil steranes have been used to draw inferences about aerobiosis in the early Precambrian. |
| These results strongly suggest that arcA but not crp or etrA plays a substantial role in the bacterial aerobiosis. |
| There are practically no qualitative differences, whether the yeast is in aerobiosis or anaerobiosis, but the quantitative differences are important. |
| The apparent contradiction with other studies reporting that aerobiosis enhances biofilm formation may rely on differences in experimental conditions and on the strain that were used. |
| In addition, the involvement of Crp in aerobiosis was indicated by a significant reduction in cytochrome c synthesis in the crp deletion mutant in the presence of oxygen. |
| Modeling is facilitated by the restriction to steady state conditions and the use of the aerobiosis scale. |
