Diversity of carotenoid synthesis gene clusters from environmental Enterobacteriaceae strains

Article Abstract:

Several new carotenoid synthesis gene clusters from environmental Enterobacteriaceae strains that produce zeaxanthin and derivatives of this compound are isolated from a variety of environmental samples. The expression of the crtEYIB genes with and without idi has confirmed the effect of increasing carotenoid titer by the type II idi gene linked with the carotenoid synthesis gene clusters.

Phage tail-like (high-molecular-weight) bacteriocins of Budvicia aquatica and Pragia fontium (Enterobacteriaceae)

Article Abstract:

Electron microscopic analysis is performed on the contractile phage tail-like bacteriocins of three Pragia fontium strains and one Budvicia aquatica strain. Fonticin and aquaticin are remarkably heat sensitive but trypsin resistant and simultaneous production of contractile and flexible phage tail-like bacteriocins in the Pragia fontium 64613 strain is shown for the first time.

Evolutionary relationships of "Candidatus Riesia spp.," endosymbiotic Enterobacteriaceae living within hematophagous primate lice

Article Abstract:

The molecular characterization of the P-endosymbiont of primate lice, including head and body lice (Pediculus humanus) which was carried out by employing full-cycle rRNA approach, including comparative 16S rRNA gene analysis and the detection of endosymbionts within the host cell by means of fluorescent in situ hybridization is presented.
