Project description:The study identified a total of 3169 gene transcripts (98.4% coverage). By comparing the anaerobic versus aerobic H2-oxidizing At. ferrooxidans cultures, a total of 371 DEGs were found. Of these, 168 DEGs were increased significantly during the aerobic growth on H2 (with O2 as the sole electron acceptor), while 203 DEGs increased significantly during anaerobic growth on H2 (with Fe3+ as the sole electron acceptor).
Project description:The deleterious fluoride ions, which released from fluoride in uranium during its bioleaching, strongly influenced microbial growth, energy intake, enzyme activity and relative metabolism. Whole-genome microarrays were used to obtain a comprehensive description of the molecular response by A. ferrooxidans ATCC 23270 at 4.8 mM fluoride stress.
