Mesorhizobium denitrificans sp. nov., a novel denitrifying bacterium isolated from sludge.

A Gram-stain-negative, non-spore-forming, facultative, rod-shaped bacterium (designated LA-28) was isolated from a sludge sample from a wastewater treatment plant in Hanam city, Republic of Korea. On the basis of 16S rRNA gene sequencing, strain LA-28 clustered with species of the genus Mesorhizobium and appeared closely related to M. jarvisii LMG 28313 (96.

Sunglasses, the European directive and the European standard.

Purpose: The Optics and Radiometry Laboratory (ORLAB) provides a testing service for the Australian sunglass industry to assist its compliance with the mandatory Consumer Product Safety Standard. In doing so, a number of sunglasses carrying the CE mark (in effect a claim of compliance with the European Union Personal Protective Equipment Directive) have been tested. Since there is no mandatory testing in Europe (the sunglass industry is deemed self regulating), evaluating their performance will give an insight into compliance with the Directive.
