In this article, we present an overview on the role of marine pollutants in impairment of DNA integrity in marine gastropods exposed to xenobiotics released from various sources into the coastal ecosystem. We provide an insight into the impact of various types of genotoxic compounds on the physiologic status of marine organisms, with specific focus on DNA integrity. DNA damage in marine gastrop...

Variations on hydrophobicity were monitored in two marine obligate hydrocarbonoclastic bacteria: Alcanivorax borkumensis SK2T and Thalassolituus oleivoras MIL-1T. These strains were inoculated, separately in ONR7a mineral medium with different concentration of sodium acetate. During 10 days measurements of cellular abundance and cellular hydrophobicity (capacity to adhere at polystyrene) were c...

Marine bacteria require a significant amount of NaCl for optimal growth and have quite different physiological character from terrestrial counterparts. For example, marine bacteria possess a unique type ofNADH:quinone reductase, a membrane-boundenzymewhich takes part in the respiratory chain1}. This enzyme requires Na+ for its activity and with its Na+-pumping activity generates sodium-motive f...

background facultative marine fungi could potentially be arsenic tolerant and may be able to remove this highly poisonous metal from the environment. objectives the objective of this work was to explore the degree of tolerance and removal efficiency of two facultative marine fungi. materials and methods facultative marine fungi aspergillus flavus and rhizopus spp. were exposed to 25 mg/l and 50...
