Immunoglobulin is a highly diverse autologous molecule able to influence immunity in different physiological and diseased situations. Its effect may be visible both in terms of development and function of B and T lymphocytes. Polyclonal immunoglobulin may be used as therapy in many diseases in different circumstances such as primary and secondary hypogammaglobulinemia, recurrent infections, pol...

The current global economy relies on fossil fuels, therefore air pollution concentration rises every day. With a growing population and industrial development, comes an increase in energy demand, need for greater sanitary infrastructure, and an urge for minimal ecosystem damage. Many successful articles about biological hydrogen production were recently approved by major international journals,...

Twenty isolates of Penicillium oxalicum produced secalonic acid as their major secondary metabolite. Fermentation conditions were determined for toxin production in grain and liquid media. The 50% lethal dose value for mice ranged from 26.5 to 51.7 mg/kg dependent on animal strain and sex, males being more susceptible than females. Secalonic acid was nontoxic and nonteratogenic to the chicken e...

Hydrogen is a clean and efficient fuel, considered as a potential and more sustainable energy substitute for fossil fuels. Biological hydrogen production stands out as an eco friendly process carried out under mild operating conditions with renewable resources. In the current work laboratory scale production of hydrogen using phototrophic purple non-sulphur bacteria Rhodobacter sphaeroides, ana...

Sulfur-/sulfate-reducing bacteria (SRB) have been used for remediation of metalcontaminated ground water and soil through the precipitation of metal sulfides. These metal sulfides range from 3 nm to 3 μm in diameter. Of specific interest to this research are zinc sulfide nanoparticles (ZnS NPs) produced by SRBs with a diameter of ~3 nm. These ZnS NPs can be used as catalysts to grow nano-wires,...
