Select the correct statement. Statement-I: Thermoacidophiles are obligate anaerobes and heterotrophs. Statement-II: They use elemental sulfur and produce hydrogen sulfide.
Options
- AStatement-I is true and Statement-II is false
- BStatement-II is true and Statement-I is false
- CBoth the statement-I and statement-II are false
- DBoth the statement-I and statement-II are true
Correct answer
D. Both the statement-I and statement-II are true
Step-by-step solution
Archaebacteria are most primitive organism which lives in most harsh habitat where no other living organism can survive. Thermoacidophiles are obligate anaerobes and heterotrophs. All species of thermoacidophiles grow at a temperature of 60°C and pH 2. They use elemental sulfur and produce hydrogen sulfide. These are extremophilic microorganisms, belonging to the genus Thermoplasma. Thermoacidophiles live in hot sulphur springs having very high temperatures and highly acidic condition.
