Bdellovibrio bacteriovorus

Bdellovibrio Bacteriovorus

By: Drew Skidmore


Structure classification

Structure / Classification

  • Gram negative

  • Curved bacilli

  • Long flagellum

  • A delta proteobacteria

  • Exist independently


Habitat metabolism

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


Adaptations

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


Bdellovibrio bacteriovorus

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
