Decolourization of wastewater from a textile plant by a marine Aspergillus niger was studied. The fungus was previously isolated from Gorgan Bay in the Caspian Sea. The kinetics of decolourization was studied by varying energy sources. The best decolourization was achieved when sucrose was used as source of carbon and energy. NH4+ ion was demonstrated to be the best nitrogen source. Color reduc...

This paper focuses on heavy metal distribution patterns in sediments of central Guilan (CG) and east Mazandaran (EM) in the south Caspian Sea coasts, north of Iran. Sediment sub-samples were retrieved from core and surficial samples in different environments of marine and coastal lagoons as well as coastal outcrops. Inductively Coupled Plasma Mass Spectrometry and Atomic Emission Spectrometry (...

Actinomycetes are interesting as a main producer of secondary metabolites and industrial antibiotics from marine environments. A total of 44 strains of actinomycetes were isolated from Caspian Sea sediments at a depth of 5-10 m. Preliminary screening was done using cross-streak method against 2 gram-positive and 4 gram-negative pathogen bacteria. The most potent strains MN2, MN3, MN38, MN39, MN...

North Atlantic climate variability does not only have an influence on North Atlantic ecosystems as described in the previous chapters and by Drinkwater et al. (2003), but influences terrestrial and freshwater ecosystems across the Northern Hemisphere (Ottersen et al. 2001; Mysterud et al. 2003; Stenseth et al. 2002; Straile et al. 2003b). Its impact on freshwater ecosystems has been documented ...
