It is known that many soil fungí synthesize brown, large aromatic polymers (fungal melanins), chemically related to soil humic acids (Martin and Haider, 1971; Schnitzer and Neyroud, 1975). Since the chemical constituents (or at least, their degradation products) and the physicochemical properties of fungal melanins are comparable to those of humic acids, it is possible that fungal metabolism ma...
Silver nanoparticles (Ag NPs) are widely used for their antimicrobial activity and consequently the particles will become environmental contaminants. This study evaluated in sand and soil matrices the toxicity of 10nm spherical Ag NPs (1 and 3 mg Ag/L) toward a beneficial soil bacterium, Pseudomonas chlororaphis O6. In sand, both NP doses resulted in loss in bacterial culturability whereas in a...
