  1. Bdellovibrio Bacteriovorus By: Drew Skidmore

  2. Structure / Classification • Gram negative • Curved bacilli • Long flagellum • A delta proteobacteria • Exist independently

  3. Habitat / Metabolism • Found in the ocean and fresh water • 6°C to 37°C • Chemoheterotroph • Also found in land habitats and the intestines of mammals • Eat gram negative bacteria that often cause disease in plants, animals, and humans • It is both aerobic and anaerobic but it works faster in an aerobic environment

  4. Adaptations • Two phases of life, attack stage and growth stage • Very small 0.2 to 0.5 micrometers x 0.5 to 1.4 micrometers • Can move 100 cell lengths per second • Grows inside the prey cell and can increase its length up to 20 times • Cell then bursts and the cycle repeats

  5. Wow • Used to fight food borne illness and can destroy 90% of an E. Coli colony in an hour • Moves at a speed that is equivalent to a human running at 600 km/hr • Bore into the prey cell at over 100 rotations per second
