Photobioreactor - Definition, Glossary, Details.

 

A photobioreactor is a bioreactor which incorporates some type of light source. Virtually any translucent container could be called a photobioreactor, however the term is more commonly used to define a closed system, as opposed to an open tank or pond. Because these systems are closed, all essential nutrients must be introduced into the system to allow algae to grow and be cultivated. A pond covered with a greenhouse could be considered a photobioreactor. A photobioreactor can be operated in "batch mode" but it is also possible to introduce a continuous stream of sterilized water containing nutrients, air, and carbon dioxide.Algae can also be grown in a photobioreactor. As the algae grows, excess culture overflows and is harvested. If sufficient care is not taken, continuous bioreactors often collapse very quickly, however once they are successfully started, they can continue operating for long periods. The photobioreactor is designed to provide optimal illumination, mixing, CO2 mass transfer, and nutrients to the phototrophic liquid suspension.

Types of photobioreactor -

  • Tubular Reactors
    • Horizontal
    • Vertical
  • Flat panel reactors
  • Vertical column reactors
  • Bubble column reactors
  • Air lift reactors
  • Stirred tank photobioreactors
  • Immobilized bioreactors

    1. A photobioreactor is a bioreactor which incorporates some type of light source. Virtually any translucent container could be called a photobioreactor, however the term is more often used to define a closed process, as against an open tank or pond. Because these systems are closed, all essential nutrients must be introduced in to the process to permit algae to grow and be cultivated. algae bioreactor design

    Influenza A detection by MDCK cell line

    The influenza A (IA) virus is the principal cause of the outbreaks of flu. A large number of laboratories participate in the worldwide surveillance of influenza virus activity and contribute to the early recognition of newly emerging epidemic strains. Differentiation between influenza A and B viruses and determination of the subtypes of influenza A virus isolates are the first steps in the characterization of influenza viruses. This analysis is traditionally done by hemagglutination inhibition (HI) tests with specific antisera raised in ferrets, chickens, or sheep.
    The diagnosis of Influenza A is largely clinical. Nevertheless, it is necessary to carry out some form of rapid antigenic diagnosis and the culture of respiratory samples to confirm the etiology of the respiratory disease and to determine the antigenic characteristics of the epidemic strains. Although the “gold standard” isolation technique is inoculation in embryonated hens’ eggs, the technical difficulties involved and …
