About E85 Fuel

  • It is a high-ethanol blended fuel comprising 80–85 per cent ethanol and 14–19 per cent petrol, specifically designed for use in flex-fuel vehicles.

Recently, scientists at Agharkar Research Institute (ARI), Pune have discovered a new species of Foraminifera and named it Portatrochammina bharatensis.

About Foraminifera

  • It is a group of single-celled organisms that have inhabited the world’s oceans for over 500 million years.
  • The shells have hundreds of tiny holes called foramen, the Latin word for window. 
  • They are among the most abundant and ecologically important organisms in the ocean.

Features of Foraminifera

  • Size: They are generally sand-grain size, measuring between 500 and 50 µm.
  • Habitat: They live in the open ocean, along the coasts, and in estuaries. 
  • Most have shells for protection and either float in the water column (planktonic) or live on the sea floor (benthic). 
  • They construct their intricate shells, called “tests,” from materials they scavenge from their surroundings (agglutinating mineral grains). 
  • Most of foraminifera” ‘crawl around’ using their pseudopodia. 
  • They don’t have a wall around their cell membranes, they are extremely flexible and can change shape.
  • The organism pushes extensions of its cytoplasm called pseudopodia (or false feet) through these holes to gather food.
  • Diet: Foraminifera eat detritus on the sea floor and anything smaller than them: diatoms, bacteria, algae, and even small animals such as tiny copepods.
  • They build complex shells, consisting at their simplest of one chamber (like a vase or tube) to many chambers that coil in elaborate ways.
