Calcium chloride (CaCl2) is an inorganic chemical from the group, and it widely used as one of snow removal agents on road in winter. Laboratory experiments were conducted to examine effects salt (NaCl) soil organisms (a animal, microorganisms, plankton). The dwelling Armadillidium vulgare died high concentration calcium treatment. longer processing time A. at chloride, lower survival rate. 16%...

Tillage practices on soils are effective for enhancing the soil’s structure and other physicochemical components. The present study was undertaken to investigate whether tilling of oil-contaminated can improve remediation efficiency soil. In study, activities principally carried out by just turning mixing in experimental bowls. Top soil obtained as pooled thoroughly mixed with spent engine oil ...

Defined media permitting extensive growth of representative pink radio-resistant tetracocci (Micrococcus radiodurans, Micrococcus roseus, and Micrococcus radiophilus) and two controls (an ultraviolet-sensitive mutant of M. radiodurans and Micrococcus luteus) are described. Availability of Fe (especially Fe3+) proved essential for good growth, as evidenced by (i) favorable effects of hydroxamic ...

The bacterial infection is an important economic and limiting factor in intensive fish production. The present study focuses on investigation of the bacterial population associated with farmed common carp fingerlings, its environment and limnological quality of pond, during winter and summer season. It was found that the bacterial count in the pond sediment (6.40 cfu x 10(4)) was about 10 times...

BACKGROUND Phlebotomine sand flies are the vectors of the leishmaniases, parasitic diseases caused by Leishmania spp. Little is known about the prevalence and diversity of sand fly microflora colonizing the midgut or the cuticle. Particularly, there is little information on the fungal diversity. This information is important for development of vector control strategies. METHODOLOGY/PRINCIPAL ...

The structural genes encoding the two essential components A and B of hexaprenyl diphosphate synthase, which produce the precursor of the prenyl side chain of menaquinone-6, were cloned from Micrococcus luteus B-P 26.
