Nanoparticles containing tungsten and molybdenum in microbial biofilms

Abstract

Article discusses examples of experiments devoted to biotechnology of metals.Nanosized particles of Mo and W were obtained and observed.

Analysis of some aspects of microorganisms application for inorganic and minerals treatment

“…Immobilization of microorganisms and their metal salts in the form of nanoparticles is also of great researchers interest today [9,10]. It is known, that aerobic bacteria of the genus Bacillus widely used in medicine and agriculture are capable of reducing Ag + ions to Ag 0 and accumulate metal nanoparticles of 5-15 nm size [22].…”

“…Each type of bioprocess we have mentioned, may have its work cycle duration different from others. For example, the process of biosorption of heavy metals or nanoprecipitates formation can only take a few minutes [5,9,10]. Biodegradation of oil can last for days and weeks.…”
