Anaerobic reduction of hexavalent chromium by subsurface microorganisms.
(1999)
Anaerobic sediments from an aquifer contaminated with landfill leachate were used to study the potential for microbial reduction of Cr(VI) to Cr(III). The lightly colored, sandy sediments slowly reduced Cr(VI) in viable, ...
Discovery, purification and characterization of antifungal proteins and other defense-related compounds from tropical plants.
(1999)
To date, we have screened 164 extracts from over 100 different plant species for antifungal activity against Fusarium chlamydosporum, a saprophytic/pathogenic fungus. Out of these 164 crude extracts, 111 had antifungal ...
The ecology and biogeochemistry of sulfate reduction in the terrestrial subsurface.
(1999)
I believe that the ubiquity and importance of sulfate reduction in subsurface environments is a reflection of the diversity of the hydrological and biogeochemical processes which contribute to the availability of sulfate. ...
A study of the regulation of transcription in Saccharomyces cerevisiae and Escherichia coli.
(1999)
The focus of this work is to determine the molecular mechanisms involved in rRNA synthesis. More specifically, this research determined which component of the RNAP I transcription complex is involved in the down-regulation ...
Development, analysis and use of an expressed sequence tag database from the multicellular asomycete, Aspergillus nidulans.
(1999)
Since these ESTs are a rich resource of expressed gene sequences useful to the large community of fungal researchers, the resulting EST database was made publicly available by submission to GenBank and placement on the ...
Bioenergetic perspectives of syntrophic substrate degradation.
(1999)
The anaerobic bacteria Syntrophomonas wolfei, Syntrophus gentianae, Syntrophus buswellii, and Syntrophus aciditrophicus grown in coculture with a hydrogen-consuming partner degraded butyrate and benzoate to a threshold ...
