pollution of marine waters is one of the important issues that has a irreparable effects. also, in the organic oil pollutants, due to inappropriate effects on the environment and humans health and ability to create cancer, hydro carbons of polycyclic (pahs) and heavy metals (ni,hg,v) have a particular importance. according to the importance of study of the environ mental contaminants in the fou...

three marine bacteria, pseudomonas putida ptcc 1664, bacillus cereus  pttc 1665 and pseudomonas pseudoalkaligenes ptcc 1666 isolated from the east anzali wetland sediments of the caspian sea, were resistant to heavy metals of cadmium (cd), nickel (ni) and vanadium (v). pseudomonas pseudoalkaligenes ptcc 1666 was found to be resistant to all 3 metals ni, cd, v. heavy metal uptake was determined ...

the aim of this research was to optimize bioremediation of seawater samples spiked with 1000 mg/l crude oil for removal of n-alkanes (c12h26 to c34h70). bioaugmentation experiments were performed at laboratory scale: each bioreactor contained 250 ml dispersed crude-oil-contaminated seawater, indigenous acclimatized microorganism and nitrogen and phosphorus at concentrations based on central com...

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...

programmed cell death, which can be classified into apoptosis, autophagy, and oncosis, based on the cellular signalling pathways involved in the process, plays a critical role in cellular house-keeping. aberrant cell death regulation leads to body malformations, as well as to numerous diseases. here, we describe the effects of cytototoxins isolated from marine organisms on the various programme...

Coastal ecosystems of Bushehr are shallow environments subject to human impacts, including shrimp aquaculture and urban expansion activities. A spatial-temporal study was conducted in order to assess the actual ecological status of the creeks, estuary and marine sites on the basis of their taxonomic composition and density of mesozooplankton. Zooplankton species distribution and abundance data ...
