    We examined the biodiversity of bacteria associated with oyster-shell waste during a 1-year storage period using 16S ribosomal DNA analysis. Temperature variation and structural changes of oyster shell were observed during storage. Initial and final temperatures were at 16-17 degrees C, but a hi...
  9. Influence of host plant genotype, presence of a pathogen, and coinoculation with Pseudomonas fluorescens strains on the rhizosphere expression of hydrogen cyanide- and 2,4-diacetylphloroglucinol biosynthetic genes in P. fluorescens biocontrol strain CHA0.

    Microbial Ecology 57(2):267 (2009) PMID 19030916

    The production of hydrogen cyanide (HCN) and 2,4-diacetylphloroglucinol (DAPG) is a major factor in the control of soil-borne diseases by Pseudomonas fluorescens CHA0. We investigated the impact of different biotic factors on the expression of HCN-in comparison to DAPG biosynthetic genes in the ...
  10. Southern African biological soil crusts are ubiquitous and highly diverse in drylands, being restricted by rainfall frequency.

    Microbial Ecology 57(2):229 (2009) PMID 18850242

    Biological soil crusts (BSCs) are found in all dryland regions of the world, including the polar regions. They are also known to occur in the southern African region. Although there were a number of case studies on BSCs from that region, we did not know if they are a normal part of the vegetatio...
  11. Identification and genetic characterization of phenol-degrading bacteria from leaf microbial communities.

    Microbial Ecology 57(2):276 (2009) PMID 19034559

    Microbial communities on aerial plant leaves may contribute to the degradation of organic air pollutants such as phenol. Epiphytic bacteria capable of phenol degradation were isolated from the leaves of green ash trees grown at a site rich in airborne pollutants. Bacteria from these communities ...
