Root nodules of plants grown on salt–affected soils: A useful source for isolating salinity tolerant N2–fixing non–rhizobial bacteria

Root nodules of plants grown on salt–affected soils. AoS

Salinity is one of the most significant environmental challenges limiting plant productivity, particularly in arid and semi–arid climates. Soil salinity affects about 800 million hectares of arable lands worldwide. Therefore, there is a need to exploit the

Origin and fate of radionuclides in Swiss soils

Soils profiles from protected recharge fields used for drinking water production were drilled and analysed for radionuclides, such as radiocesium (137Cs), radiostrontium (90Sr) and plutonium (239+240Pu). Inventories and distribution of the radionuclides were compared with an uncultivated

Cs adsorption sites in clay influenced by solution concentration

Since the nuclear crisis at Fukushima, the Cs decontamination works have yielded a large amount of contaminated soil. The urgency of reducing the volume of contaminated soil has become a serious concern with respect to the acceleration

Sequence of the plant beneficial biocontrol agent Pseudomonas fluorescens DSM 8569

Pseudomonas represents an abundant bacterial group that can live in the soil. In this habitat many organisms like fungi, bacteria, plants or insects live together, often intensively interacting in close communities. The composition of these communities is

Assessment of the influence of traffic-related particles in dust

Dust particles present in our daily lives consist of a mixture of materials from different sources, such as soils, traffic-related particles, pavement particles, etc. Due to their low particle size, dust particles can be easily re-suspended and
