New bacteria that was provided from contaminated soils surrounding the coal, aluminum, salt mines and wetland separated, synthesized and characterized. The achievements show that this soils and waters have five disposed bacteria consist of Microbacterium SP, Micrococcaceae Bacterium, Planomicrobium SP, Brevndimonas Aurantiaca and Halomonas SP. Secondly, the result of the potential of remova...

An enrichment culture procedure for isolating members of the genus Acinetobacter from soil and water is described. It involves the use of vigorously aerated mineral media at relative low pH, supplemented with acetate or other suitable carbon source and nitrate as nitrogen source. With this method, virtually all samples of soil and water yielded representatives of this genus. Semiquantitative co...

In Israel with its semi-arid climate, water is a limited resource and yet, in the last two decades about 60% of all of Israel’s water resources are directed for agricultural use. This is feasible due to the capacity to recycle water. Treated wastewater (TWW) has become an important source of irrigation water in Israel and other parts of the world due to the pressures of increasing population an...

Survival and transport of pathogens from manure in the environment depend on a number of complex phenomena. An important question is how the properties of such a complex environment as the soil–manure medium impact the persistence of bacteria within the vadose zone. First, manure can change the partitioning of precipitation water between infiltration (enhanced by solid manure) and surface runof...

Our understanding of the effects of elevated atmospheric CO2, singly and in combination with other environmental changes,on plant-soil interactions is incomplete. Elevated CO2 effects on C4 plants, though smaller than on C3 species, are mediated mostly via decreased stomatal conductance and thus water loss. Therefore, we characterized the interactive effect of elevated CO2 and drought on soil m...

The effects of biochar application to calcareous soils are not well documented. In a laboratory incubation study, a hardwood-based, fast pyrolysis biochar was applied (0, 1, 2, and 10% by weight) to a calcareous soil. Changes in soil chemistry, water content, microbial respiration, and microbial community structure were monitored over a 12-mo period. Increasing the biochar application rate incr...

Groundwater is considered to be of excellent quality because of the soil barrier providing effective isolation of this high quality source water from surface pollutants. This is true for most groundwater resources although we know that many aquifers all over the world are polluted and/or is being polluted [1-4]. Habitats containing only a single kind of microorganism are found only in the labor...
