Methane oxidation in termite hindguts: Absence of evidence and evidence of absence

Article Abstract:

A study was carried out to resolve the issue of methane oxidation within termite hindguts by experimentation with various representations from the most species-rich termite families. The evidence from the study suggests that methane is not oxidized in the termite hindgut and that methane-oxidizing bacteria are absent, irrespective of the phylogenetic status and feeding guild of the host.

Localization and in situ activities of homoacetogenic bacteria in the highly compartmentalized hindgut of soil-feeding higher termites (Cubitermes spp.)

Article Abstract:

Research was conducted to examine distribution and abundance of hydrogen utilizing baceria and the source of hydrogen in the hindgut of soil-feeding termites. The data show that increased levels of hydrogen partial pressure in the hindgut of termites favor higher populations of the baceria.

The termite group I phylum is highly diverse and widespread in the environment

Article Abstract:

Phylogenetic analysis is conducted to investigate the environmental distribution of major lineages of termite group I (TG-1) bacteria in soils, sediments and intestinal tracts. It is observed that bacteria affiliated with TG-1 phylum form a separate line of descent.
