Four bacterial strains that oxidize L-sorbose to 2-keto-L-gulonic acid, a key intermediate in the synthesis of vitamin C, were isolated from soils of geographically distinct locations. All were Gram-negative, facultatively anaerobic, chemoheterotrophic rods. Comparative analysis revealed nearly identical 16S rDNA sequences amongst them (99.7-100% identical) and identified them as members of the...

The recognition of cryptic parasite species has implications for evolutionary and population-based studies of wildlife and human disease. Echinostome trematodes are a widely distributed, species-rich group of internal parasites that infect a wide array of hosts and are agents of disease in amphibians, mammals, and birds. We utilize genetic markers to understand patterns of morphology, host use,...

Lichens are symbiotic associations of fungi with microalgae and/or cyanobacteria. Lichens belonging to the Parmeliaceae family comprise 2700 species of lichens, including the Parmotrema genus which is composed of 300 species. The metabolites of this genus include depsides, depsidones, phenolics, polysaccharides, lipids, diphenylethers and dibenzofurans, which are responsible for the biological ...
