D-glucaric acid and galactaric acid catabolism by Agrobacterium tumefaciens.

abstract：:PB15 is an Hfr strain of Escherichia coli K-12. It arose from an F' strain carrying a temperature-sensitive F-gal by an event which blocked the detachment of F-gal in the normally reversible integration process. In PB15, the detachment of F-gal by a second mechanism can now be detected: this mechanism results in the e...
