- Abstract
Effect of deletion of acid resistant genes of E. coli on the high-pressure carbon dioxide (HPC) resistance was investigated. Genes coding amino acid decarboxylases, such as lysine, arginine, and glutamate decarboxylase, were found to contribute to HPC resistance. Protonophore-treated cells showed hypersensitivity to HPC, confirming that HPC induced cytoplasm acidification and exerted severe damage on cells by intrusion of gaseous carbon dioxide into cytoplasm.
