Acid-loving Archaebacteria, Acidothermus pHabilis, unicellular prokaryote

A. Kingdom Archaebacteria (Domain: Archaea) Common Name: Acid-Loving Microbe Scientific Name: Acidothermus pHabilis Cell Type & Number of Cells: Prokaryote, Unicellular Mode of Nutrition: Autotroph Specific Example of Food Source: Carbon dioxide and hydrogen sulfide from hot springs Mode of Reproduction: Asexual (Binary Fission) Habitat: Hot, acidic water pools Describe Habitat Characteristics: Temperature: 80-90°C (176-194°F), weather is stable and usually humid, sunlight is limited with geothermal energy as the primary light source. Specialization to Habitat: Food Acquisition: Enzymes that break down hydrogen sulfide for energy Highly developed cell membranes resistant to extreme acidity Survival/Defense: Synthesize proteins that stabilize under high temperatures Structural adaptations to prevent cell wall degradation in low pH (illustration of Acid-Loving Microbe in hot and acidic water pools) Mehr sehen
