Diversity and structure of bacterial chemolithotrophic communities in pine forest and agroecosystem soils
Article Abstract:
The diversity and structure of bacterial chemolithotrophic communities obtained from two sites in a Georgia agroecosystem and an unmanaged pine stand are investigated. The results indicate that lithotrophic populations respond differentially to plant type and land use and the paucity of clone sequences attributed to ammonia-oxidizing bacteria shows that even though ammonia oxidation occurs in the various soils, the relevant populations are small compared to those of facultative lithotrophs.

Analysis of facultative lithotroph distribution and diversity on volcanic deposits by use of the large subunit of ribulose 1,5-bisphosphate carboxylase/oxygenase
Article Abstract:
PCR from facultatively lithographic aerobic CO oxidizing bacteria, sulfide-oxidizing microbial mats and genomic DNA extracts from tephra and ash deposits from Kilauea volcano were used for amplifying the gene coding for the large subunit of ribulose 1,5-bisphosphate carboxylase/oxygenase (RubisCO) (rbcL). Distinct populations of undescribed facultative lithographs among recent volcanic deposits differing in age and successional state are shown by the rbcL sequence data.

Phylogeny of 16S rRNA, ribulose 1,5-bisphosphate carboxylase/oxygenase, and adenosine 5'-phosphosulfate reductase genes from gamma-and alphaproteobacterial symbionts in gutless marine worms (oligochaeta) from Bermuda and Bahamas
Article Abstract:
The diversity of bacterial endosymbionts in Inanidrilus leukodermatus from Bermuda and Inanidrilus makropetalos from Bahamas was studied using comparative sequence analysis of 16S rRNA gene and fluorescence in situ hybridization. The findings show that stable coexistence of multiple endosymbionts is not limited to single species but appears to be a common feature in oligochaete symbioses.
