Physiological ecology of Stenoxybacter acetivorans, an obligate microaerophile in termite guts

Article Abstract:

Molecular and physiological approaches are used for determining the primary location of Stenoxybacter acetivorans cells and identify key genes and gene products involved in acetate utilization and oxygen consumption by Stenoxybacter acetivorans. Respirometric measurements have shown that the [O.sub.2] consumption by Reticulitermes flavipes worker larvae is attributed to their guts and the contribution of Stenoxybacter acetivorans to [O.sub.2] consumption by extracted guts is similar to that obtained for other hindgut bacteria.

New strategies for cultivation and detection of previously uncultured microbes

Article Abstract:

A PCR-based procedure, plate wash PCR, which facilitated the surveillance of isolation plates for the presence and recognition of colonies made up of target organisms, was developed. The results illustrated the power of integrating culture methods with molecular techniques to isolate bacteria from phylogenetic groups under-represented in culture.

Isolation and characterization of soil bacteria that define Terriglobus gen. nov., in the phylum acidobacteria

Article Abstract:

The metabolic properties and potential ecological roles of members of the phylum Acidobacteria are studied by cultivating and characterizing new strains from terrestrial habitats. The results from the physiological and phylogenetic characterization have created a new genus, Terriglobus.
