  dolphin is specially found and protected in lower ganga which flows in bhagalpur district bihar.
  I am adding few more information.

  Vikramshila Gangetic Dolphin Sanctuary is located in Bhagalpur District of Bihar, India. The sanctuary is a 50 km stretch of the Ganges River from Sultanganj to Kahalgaon. Designated in 1991, it is the only protected area for the endangered Gangetic dolphins in Asia. Once found in abundance, only a few hundred remain, of which half are found here.

  The Gangetic dolphins have been declared as the National Aquatic Animal of India.[1] This decision was taken in the first meeting of the National Ganga River Basin Authority (NGRBA) chaired by Prime Minister Dr. Manmohan Singh on Monday, 5 October 2009.[2][3]

  THREATS ;;;;;

  Multiple dams and barriers disrupting free movement of the dolphins.

  Pollution by fertilisers, pesticides and industrial and domestic effluents, which are responsible for the death of many fish and are likely to have a negative effect on dolphin population.

  Killing of the animals for their meat or oil (used as catfish bait), and accidental entanglement in fishing nets.

  CONSERVATION;;;;;;;

  There are various conservation works going on the Sanctuary Area. Noted works are:
  The Vikramshila Biodiversity Research and Education Centre (VBREC), led by Dr. Sunil Chaudhary, together with the Whale and Dolphin Conservation Society (WDCS), the Environmental Biology Laboratory of Patna University, and T.M. Bhagalpur University, has initiated a project to improve the conservation value of Vikramshila Gangetic Dolphin Sanctuary.

  Aaranyak, a registered conservation NGO working in North East India since 1989, has initiated a project entitled “Conservation of Gangetic dolphin in Brahmaputra river system, India” in collaboration with Dibrugarh University (Assam). The project aims to evaluate the conservation status of the Ganges River dolphin throughout the entire Brahmaputra river system by carrying out research into the species’ population status, distribution, habitat preferences and threats.
  WWF India also had started The Dolphin Conservation Programme to conserve the habitat of the Ganges River Dolphin and secure a future for the endangered species.

  National Microbe

  Lactobacillus delbrueckii subspecies bulgaricus (until 1984 known as Lactobacillus bulgaricus) is one of several bacteria used for the production of yogurt. It is also found in other naturally fermented products. First identified in 1905 by the Bulgarian doctor Stamen Grigorov, the bacterium feeds on lactose to produce lactic acid, which is used to preserve milk.

  It is a Gram-positive rod that may appear long and filamentous. It is non-motile and does not form spores. It is regarded as aciduric or acidophilic, since it requires a low pH (around 5.4–4.6) to grow effectively. The bacterium has complex nutritional requirements

  Kingdom: Bacteria
  Division: Firmicutes
  Class: Bacilli
  Order: Lactobacillales
  Family: Lactobacillaceae
  Genus: Lactobacillus
  Species: L. delbrueckii
  Subspecies: L. d. bulgaricus

  Trinomial name: Lactobacillus delbrueckii subsp.bulgaricus

  Additional Info:

  The main difference between gram negative and gram positive bacteria has to do with the arrangement of the outer portions of the cell.

  In general, gram positive bacteria tend to persist in dry environments better and are often found on places like the skin and in dust.

  Gram negative bacteria, on the other hand, are killed more quickly by drying but thrive in aqueous environments. Gram negative bacteria also tend to grow better in the presence of toxic chemicals (such as chlorine), a feat thought to be enabled by their two cell membranes.
  Gram positive and gram negative refers to how a bacteria reacts to a gram stain. If it takes the initial stain, it will be purple/bluish and be considered gram positive. If it doesn’t take the initial stain, it will be pink and gram negative.

  The difference is the outer casing of the bacteria.

  A gram positive bacteria will have a thick layer of peptidoglycan (a sugar-protein shell) that the stain can penetrate.

  A gram negative bacteria has an outer membrane covering a thin layer of peptidoglycan on the outside. The outer membrane prevents the initial stain from penetrating.
