Our interest in the microbial breakdown of uranic acids stems from this group’s earlier studies (1,2) on the catabolism of pectin by soft-rot bacteria of the genus Erwinia. In those investigations it had been shown that Erwinia carotovora, when previously grown on pectin, possesses enzymes which can convert pectin to galacturonic acid, and that the galacturonate is further metabolized by galact...

Phenetic data on over 60 heterotrophic, Gram-negative, yellow chromogenic bacteria from plant material were collected and analysed using numerical taxonomic methods. Marker strains representing 42 taxa were included in the analyses. At similarity levels of 80% or above, eight distinct clusters were obtained, the first four of which included yellow chromogens. Custer I contained isolates from gr...
