Influences of phosphate on the growth and nodulation characteristics of Rhizobium trifolii

Creator:: Leung, Kam-tin
Abstract:: Nodulation success by two indigenous Rhizobium trifolii serogroups, 6 and 36, on subterranean clover (Trifolium subterraneum L.) was affected by the addition of phosphate to Abiqua soil (Ultic Haploxeroll). To understand the impact of phosphorus nutrition on the survival and nodulation characteristics of the two serogroups, studies were carried out...

Characteristics of bradyrhizobium sp. recovered from Oregon soils

Creator:: Cheng, Hsin-hua
Abstract:: Although the biology of Bradyrhizobium has been studied for almost one hundred years, virtually nothing is known about the ecology and genetic variation in natural soil populations of this genus. The majority of information has been obtained from studies of one species, Bradyrhizobium japonicum, and the diversity within soil populations...

Community profiles of ammonia oxidizers across high-elevation forest-to-meadow transects

Creator:: Mintie, Ann
Abstract:: In recent years considerable interest has been shown in the diversity of ammonia-oxidizing bacteria in soil communities. The majority of the research has been carried out in Northern Europe where soils have received high atmospheric inputs of nitrogen over the past two centuries. In contrast, although much work has been...

Symbiotic and saprophytic characteristics of a soil population of Rhizobium leguminosarum bv. trifolii

Creator:: Yap, Kathryn H. M.
Abstract:: Although much has been learned about the comparative nodulating behavior of simple mixtures of rhizobial strains under non-soil situations, it is unclear how these findings relate to the factors influencing nodulation success by the complex mixtures of strains found within soil-borne rhizobial populations. Information on the structure and physiological behavior...

Metabolism of dichloroethenes by the butane-oxidizing bacterium 'Pseudomonas butanovora'

Creator:: Doughty, David M.
Abstract:: Reductive dechlorination of chlorinated ethenes is dependent upon suitable substrates promoting microbial activity and creating anaerobic conditions. At the periphery of active reductive dechlorinating zones combinations of lesser chlorinated ethenes should exist along with end products of the anaerobic metabolism that is driving reductive dechlorination. Potential end-products of anaerobic metabolism...

Transcriptome profiling of Nitrosomonas europaea grown singly and in co-culture with Nitrobacter winogradskyi

Creator:: Pérez, José
Abstract:: In most environments, ammonia (NH₃) is oxidized to nitrate (NO₃⁻) via the intermediate nitrite (NO₂⁻). This is a microbe-driven process involving phylogenetically distinct types of microorganisms, namely, ammonia-oxidizing bacteria (AOB) and Thaumarchaea (AOA), and nitrite-oxidizing bacteria (NOB). Nitrosomonas europaea and Nitrobacter winogradskyi are the best studied AOB and NOB, respectively,...
