The vapor-phase selective oxidation of propylene (H2C CHCH3) to acrolein (H2C CHCHO) was investigated over supported V2O5/Nb2O5 catalysts. The catalysts were synthesized by incipient wetness impregnation of V-isopropoxide/isopropanol solutions and calcination at 450 8C. The catalytic active vanadia component was shown by in situ Raman spectroscopy to be 100% dispersed as surface VOx species on ...

Fungal secretomes contain a wide range of hydrolytic and oxidative enzymes, including cellulases, hemicellulases, pectinases, and lignin-degrading accessory enzymes, that synergistically drive litter decomposition in the environment. While secretome studies of model organisms such as Phanerochaete chrysosporium and Aspergillus species have greatly expanded our knowledge of these enzymes, few ha...

Extremely acidophilic iron-oxidizing Gram-positive bacteria comprise species within the phyla Firmicutes and Actinobacteria. Here, we report the 4.02-Mb draft genome of Acidithrix ferrooxidans Py-F3, which was isolated from a stream draining an abandoned copper mine and proposed as the type species of a new genus of Actinobacteria.

Bacteria in the genus Nitrosospira play vital roles in the nitrogen cycle. Nitrosospira sp. strain APG3 is a psychrotolerant betaproteobacterial ammonia-oxidizing bacterium isolated from freshwater lake sediment. The draft genome revealed that it represents a new species of cluster 0 Nitrosospira, which is presently not represented by described species.

bioleaching is the extraction of metals from their ores through the use of microorganisms. inthis process, the use of native bacteria leads to achieve more yields of metals. so, in the presentstudy, native sulfur-oxidizing bacterium in potentiality of uranium extraction was isolated fromghachin mine in iran and identified by partial gene sequencing. for this purpose, the watersamples were colle...

Solar radiation and nutrient pulses regulate the ecosystem's functioning. However, little is known about how a greater frequency of pulsed nutrients under high ultraviolet radiation (UVR) levels, as expected in the near future, could alter the responses and interaction between primary producers and decomposers. In this report, we demonstrate through a mesocosm study in lake La Caldera (Spain) t...
