In this study, we reported the morphogenetic analysis and genome sequence by genomic analysis of the newly isolated staphylococcal phage SMSAP5 from soil of slaughterhouses for cattle. Based on transmission electron microscopy evident morphology, phage SMSAP5 belonged to the Siphoviridae family. Phage SMSAP5 had a double-stranded DNA genome with a length of 45,552 bp and 33 % G+C content. Bioin...

Hochiminh City environs have more than 45,000 ha of coastal plain soils which to be continued to the South by the great mangrove forest in Camau peninsula. How to protect and afforest mangroves successfully on these soils when using them also for aquaculture (shrimp, fish, crab, mollusc, etc.)? An answer to this question is now urgently needed. Dealing with the study on soil genesis/ geography ...

A commercial scale biochar field trial was established on a farm in Québec, Canada in May 2008. A very fine, commercially available biochar from fast pyrolysis of wood waste was applied as received from the manufacturer using standard farm machinery. The target application rate was 5.6 t/ha, but an estimated 30% of the material was wind-blown and lost during handling, transport to the field, so...

Multitrophic communities that maintain the functionality of the extreme Antarctic terrestrial ecosystems, while the simplest of any natural community, are still challenging our knowledge about the limits to life on earth. In this study, we describe and interpret the linkage between the diversity of different trophic level communities to the geological morphology and soil geochemistry in the rem...

Bioremediation is a potentially cost-effective, in situ method for cleaning up NAPL-contaminated sites. The ability of microorganisms to access and degrade NAPL constituents is highly dependent on the heterogeneity of the soil and the morphology of the NAPL source. Soil heterogeneities can result in preferential pathways of air and water flow through the subsurface. Intermediate-scale studies w...

A new, multi-tracer method is used to track erosion, translocation, and redeposition of sediment in a small watershed, thus allowing for the first time a complete, spatially distributed, sediment balance to be made as a function of landscape position. A 0·68 ha watershed near Coshocton, Ohio, USA was divided into six morphological units, each tagged with one of six rare earth element oxides. Se...

A three-dimensional, nonhydrostatic, nested grid version of the Colorado State University Regional Atmospheric Modeling System (RAMS) was used to perform simulations of an actual dryline that was observed as part of the COPS-91 field experiment on 15 May 1991. A control run designed to reproduce the observed conditions as accurately as possible was generated and verified against standard Nation...

The effectiveness of magnesium as a substitute material in enzyme-mediated calcite precipitation was evaluated. Magnesium sulfate was added to the injecting solution composed of urea, urease, and calcium chloride. The effect of the substitution on the amount of precipitated materials was evaluated through precipitation tests. X-ray powder diffraction and scanning electron microscopy analyses we...

Riparian forests can provide an important service for aquatic ecosystems by sequestering hillslopederived sediments. However, the width of a riparian buffer zone required to filter sediments is not yet wellunderstood. Here are used two complementary tracers to measure sediment retention. The 137Cs technique and the soil carbon isotopic ratios (delta13C) are utilized to investigate sediment depo...

A novel black yeast-like fungus, Exophiala crusticola, is described based on two closely related isolates from biological soil crust (BSC) samples collected on the Colorado Plateau (Utah) and in the Great Basin desert (Oregon), USA. Their morphology places them in the anamorphic genus Exophiala, having affinities to the family Herpotrichiellaceae (Ascomycota). Phylogenetic analysis of their D1/...
