Question: Nitratireductor indicus is a Gram-negative, oxidase- and catalase-positive mobile bacteria from the genus of Nitratireductor which was isolated from deep-sea water of which is the third largest of the world's oceanic divisions, covering 70,560,000 km2 (approximately 20% of the water on the Earth's surface), and  bounded by Asia on the north, on the west by Africa, on the east by Australia, and on the south by the Southern Ocean or, depending on definition, by Antarctica?

Context paragraphs:
Nitratireductor basaltis: Nitratireductor basaltis is a Gram-negative, oxidase- and catalase-positive bacteria from the genus of Nitratireductor which was isolated from black sand from the Soesoggak beach on the Jeju Island in South Korea.

Nitratireductor pacificus: Nitratireductor pacificus is a Gram-negative and motile bacteria from the genus of Nitratireductor which was isolated from enriched sediment from the Pacific Ocean.

Nitratireductor kimnyeongensis: Nitratireductor kimnyeongensis is a Gram-negative, aerobic, oxidase- and catalase-positive bacteria from the genus of Nitratireductor which was isolated from the Kimnyeong Beach in Jeju from the Republic of Korea.

Nitratireductor indicus: Nitratireductor indicus is a Gram-negative, oxidase- and catalase-positive mobile bacteria from the genus of Nitratireductor which was isolated from deep-sea water of the Indian Ocean.

Psychrobacter nivimaris: Psychrobacter nivimaris is a Gram-negative, oxidase- and catalase-positive, aerobic, nonmotile bacterium of the genus "Psychrobacter", which was isolated from the Southern Ocean.

Sea: A sea is a large body of salt water that is surrounded in whole or in part by land.  More broadly, "the sea" is the interconnected system of Earth's salty, oceanic waters—considered as one global ocean or as several principal oceanic divisions.  The sea moderates Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle.  Although the sea has been traveled and explored since prehistory, the modern scientific study of the sea—oceanography—dates broadly to the British "Challenger" expedition of the 1870s.  The sea is conventionally divided into up to five large oceanic sections—including the International Hydrographic Organization's four named oceans (the Atlantic, Pacific, Indian, and Arctic) and the Southern Ocean; smaller, second-order sections, such as the Mediterranean, are known as "seas".

Hoff crab: The "Hoff crab" is a species of deep-sea squat lobster in the family Kiwaidae, which lives on hydrothermal vents near Antarctica.  The crustacean was given its nickname in 2010 by UK deep-sea scientists aboard the RRS "James Cook", owing to resemblance between its dense covering of setae on the ventral surface of the exoskeleton and the hairy chest of the actor David Hasselhoff.  The 2010 expedition to explore hydrothermal vents on the East Scotia Ridge was the second of three expeditions to the Southern Ocean by the UK led research consortium, ChEsSo (Chemosynthetic Ecosystems of the Southern Ocean).

Indian Ocean: The Indian Ocean is the third largest of the world's oceanic divisions, covering 70,560,000 km2 (approximately 20% of the water on the Earth's surface).  It is bounded by Asia on the north, on the west by Africa, on the east by Australia, and on the south by the Southern Ocean or, depending on definition, by Antarctica.  It is named after the Indian subcontinent.  The Indian Ocean is known as "Ratnākara" (Sanskrit: रत्नाकर ), ""the mine of gems"" in ancient Sanskrit literature, and as "Hind Mahāsāgar" (Hindi: हिन्द महासागर ), in Hindi.

Pacific Ocean: The Pacific Ocean is the largest and deepest of Earth's oceanic divisions.  It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south and is bounded by Asia and Australia in the west and the Americas in the east.

Martelella mediterranea: Martelella mediterranea is a Gram-negative, oxidase- and catalase-positive, strictly aerobic, non-spore-forming, non-motile bacteria from the genus of Martelella which was isolated from water sample from the Lake Martel on Mallorca in Spain.
