Myxococcus xanthus
The Coolest Bacteria
PROOF!!!
Presentation for Mrs.
James' Bio II class
Scientific Stuff
• Name: Myxococcus xanthus
• Classification:
-Actually is rod-shaped (have rounded
ends… so it’s a coccus)
-Chemoorganotrophic (chemohetero,
basically)
-Aerobic (need oxygen)
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
-
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.
Cool Stuff - 2 Mutations
• This mutation has
what is called
Adventurous
Motility (A)
39 seconds
• This mutation has
what is called
Social Motility (S)
12 seconds
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
