Exploring Myxococcus xanthus: The Coolest Bacteria in Nature

DESCRIPTION

Myxococcus xanthus is a remarkable rod-shaped, gram-negative bacterium known for its unique adaptations and ecological role. This aerobic, chemoorganotrophic organism thrives in organic soil and can survive in rocky terrains with specific pH levels. It exhibits two locomotion types, including Type IV pilli and mucus secretion, enabling a gliding motion. This bacterium collaborates with others through social motility to capture prey and forms endospores during food scarcity. Currently, it's being researched for applications in medicine, including the development of the cancer-targeting drug, Taxol.

Presentation Transcript

  1. The Coolest Bacteria Myxococcus xanthus PROOF!!! Presentation for Mrs. James' Bio II class

  2. Scientific Stuff • Name: Myxococcus xanthus • Classification: -Actually is rod-shaped (have rounded ends… so it’s a coccus) -Chemoorganotrophic (chemohetero, basically) -Aerobic (need oxygen)

  3. More Scientific Stuff • Habitat – Organic soil (has to have pH 5- 8) Can also live in rockier terrain • Special Adaptations - 2 types of locomotion 1. Type IV Pilli (used as a hook) 2. Mucus Secretion (helps it move in a 'gliding' fashion) - Has a multi-cellular synchronizing mechanism -Can talk with other cells to work together against a common prey - Can form endospores when food is not available

  4. Last of Science Stuff • Not disease-causing (not harmful to humans) • Gram-negative • Environmental Impact/ Function - Kills lots of bacteria • Cool Stuff – It is used (and still being studied) to kill harmful bacteria and fungi and is used to make antibodies which can fight off yeasts, mold, and enterobacteria.

  5. This mutation has what is called Social Motility (S) Cool Stuff - 2 Mutations • This mutation has what is called Adventurous Motility (A) 39 seconds 12 seconds

  6. More Cool Stuff • Now is being researched to make a medicine called Taxol that can target breast-cancer cells • Genome is 9.14 Mb (not mega-bytes but Mega base which is 1,000,000 base-pairs) Mass of 100,000 Myxococcus Xanthus cells with their visable spores
