TiO nanoparticles affect the bacterial community structure and (Savigny, 1826) in an arable soil.

The amount of nanoparticles (NP), such as TiO, has increased substantially in the environment. It is still largely unknown, however, how NP might interact with earthworms and organic material and how this might affect the bacterial community structure and their functionality. Therefore, an arable soil was amended with TiO NP at 0, 150 or 300 mg kg and subjected to different treatments.

Natronobacterium texcoconense sp. nov., a haloalkaliphilic archaeon isolated from soil of a former lake.

A novel haloalkaliphilic archaeon, strain B23(T) was isolated from the former lake Texcoco in Mexico. The strain was Gram-stain-negative, the cells coccoid to ovoid rods, red pigmented and aerobic. Strain B23(T) grew in 1.
