Iron-reducing bacteria and iron nanostructures

Iron Reducing Bacteria [IRB] are one of the most applicable microorganisms in various industrial and environmental activities. These bacteria play a main role in the natural iron transformation. They act in a reverse metabolic pathway in contrast to iron oxidizing bacteria. In the anaerobic conditions IRB are capable to use ferric ion as the final electron acceptor and reduce Fe3+ to Fe2+. What makes these bacteria interesting in bionanotechnology is that IRB are able to synthesize iron nanostructures. In this mini review we have a quick look on the diversity, metabolism, and cultivation of IRB. Finally, we discuss iron nano structures which biosynthesized by IRB

overview on the health benefits and production of fermented functional foods

Functional foods have a large and growing global market and are regarded as one of the most actively researched areas of food science. The growth in popularity of functional foods is attributed to the phenomena of consumer health care, increasing health awareness and knowledge in the many benefits of functional foods. Common benefits of functional foods include reduction of disease, health maintenance and prevention of nutrition related diseases. In this review, the current state and challenges for the production of functional foods by the help of bioprocess engineering are investigated. The present review also revisits the commercial impediments to provide insight for future works
