Antiviral and immunoregulatory effect of a novel exopolysaccharide from a marine thermotolerant Bacillus licheniformis.
EPS-1 is a novel extracellular polysaccharide produced by a strain of thermotolerant Bacillus licheniformis, isolated from a shallow marine hot spring of Vulcano Island (Italy). In this paper, antiviral and immunomodulatory effects of EPS-1 were evaluated. It was found that EPS-1 treatment impaired HSV-2 replication in human peripheral blood mononuclear cells (PBMC) but not in WISH cells. Since...
متن کاملManagement of chromium induced oxidative stress by marine Bacillus licheniformis
The present study describes management of oxidative stress induced by heavy metal chromium in marine Bacillus licheniformis (NCBI GenBank Accession NumberHM194725). It is identified that the isolate reduces 10-1500 mg/L of Cr (VI) within 24-72 h. Existence of chromium reductase in growth medium implies the possibility of enzymatic reduction of Cr (VI) to Cr (III). Nevertheless, no correlation w...
متن کاملAnti-biofilm activity of an exopolysaccharide from a sponge-associated strain of Bacillus licheniformis
BACKGROUND Secondary metabolites ranging from furanone to exo-polysaccharides have been suggested to have anti-biofilm activity in various recent studies. Among these, Escherichia coli group II capsular polysaccharides were shown to inhibit biofilm formation of a wide range of organisms and more recently marine Vibrio sp. were found to secrete complex exopolysaccharides having the potential for...
متن کاملIsolation and characterization of exopolysaccharide from biofilm producing marine bacteria
Marine bacterial exopolysaccharides are fascinating industrial uses and presence of bioactive compounds. In this present study , Exopolysaccharide producing Micrococcus sp isolated from Arabian Sea and was identified by morphological and biochemical characteristics. Exopolysaccharide characterized by Infra Red spectroscopy and Antibacterial activity done by disc diffusion method with the clinic...
متن کاملLead and Cadmium Bioremoval by Halomonas sp., an Exopolysaccharide-Producing Halophilic Bacterium
Toxic heavy metals, such as lead (Pb) and cadmium (Cd) are widely used in industry and their accumulation in the living tissues may cause serious health problems and ecological hazards. Twenty four moderately halophilic bacteria isolated from saline environments of Iran were used to study their ability to bioremediation of lead and cadmium. Amongst them, a Gram-negative rod shaped bacterium, de...
