Bacterial diversity in a deep-subsurface clay environment
Article Abstract:
A deep clay sediment in a 20 meter-long core from a 224 meter-deep mine gallery in the Belgian Boom clay formation shows a decrease in bacterial densities with increasing distance of the sediment from the mine gallery. However, both PCR experiments and phylogenetic analysis reveal that small contamination by active bacteria during sampling make the analysis of environments which contain only a few poorly active bacteria difficult. Some of the bacteria may derive from cells trapped during sedimentation because the porosity of the Boom clay is less than the expected bacterial size.

Protozoa in subsurface sediments from sites contaminated with aviation gasoline or jet fuel
Article Abstract:
Samples were collectedfrom the surface to below the water table in an aviation gasoline and jet fuel spill polluted site. This was done in order to determine if existing protozoan populations can significantly affect its microbial community. Fuel carbon in sediments and soil microbial activity were measured by gas chromatography and assaying dehydrogenase activity, respectively. It was found that the bacterial community that was degrading the fuel could be significantly reduced by the abundance of protozoa in the biotreatment area.

Development of fungal inocula for bioaugmentation of contaminated soils
Article Abstract:
Pelleted fungal inocula are useful in bioaugmentation of soils containing hazardous organic substances. The inocula are sensitive to growth suppression by substances such as pentachlorophenol that contaminate the soil. The fungal inocula have a pelleted core with a nutrient source, a binder, a carrier and a lubricant entrapped in a layer of fungal mycelia. The pelleted fungal inocula are low in moisture content and are capable of resisting attack from indigenous soil bacteria and fungi.
