Question

К автотрофным бактериям НЕ относится: а) железобактерия б) бактерия ботулизма в) серобактерия г) водородная бактерия

Answer 1

Железобактерия, серобактерия и водородная бактерия являются автотрофными, так как они могут синтезировать энергию из неорганических соединений. Значит, правильный ответ - бактерия ботулизма.

Answer 2

Autotrophic Bacteria

Autotrophic bacteria are organisms that can produce their own food from inorganic substances. They do not require organic compounds as a source of carbon. Let's determine which of the given options does not belong to the group of autotrophic bacteria.

The bacterium that does not belong to the group of autotrophic bacteria is: a) железобактерия

Explanation

- железобактерия: Iron bacteria are a group of bacteria that derive the energy they need to live and multiply by oxidizing dissolved ferrous iron. They are not autotrophic and do not produce their own food from inorganic substances.

- бактерия ботулизма: The bacterium that causes botulism, Clostridium botulinum, is not an autotrophic bacterium. It is a rod-shaped, anaerobic, spore-forming bacterium that produces the botulinum toxin, which is one of the most potent neurotoxins known.

- серобактерия: This term is not specific enough to determine the exact bacterium referred to. However, if it refers to sulfur bacteria, they are known to be autotrophic, using inorganic compounds as a source of energy.

- водородная бактерия: Hydrogen bacteria, or hydrogen-oxidizing bacteria, are a group of autotrophic bacteria that use molecular hydrogen as an electron donor and molecular oxygen as an electron acceptor to generate energy.

Therefore, the bacterium that does not belong to the group of autotrophic bacteria is железобактерия.
