Isolation of a mutation resulting in constitutive synthesis of L-fucose catabolic enzymes Open
A ribitol-positive transductant of Escherichia coli K-12, JM2112, was used to facilitate the isolation and identification of mutations affecting the L-fucose catabolic pathway. Analysis of L-fucose-negative mutants of JM2112 enabled us to …

Construction of an improved D-arabinose pathway in Escherichia coli K-12 Open
A ribitol catabolic pathway was transduced into Escherichia coli K-12 in an effort to determine whether the ribitol pathway would confer an advantage to D-arabinose-positive mutants growing on D-arabinose as the sole carbon source. Competi…
