Tube morphology

IMG_3705.JPG
Three organisms inoculated in TSB to look at tube morphology. From left to right:
Staphylococcus aureus: flocculent growth/turbid, growth throughout the tube.
Mycobacterium smegmatis: pellicle, growth at the top of the tube. M. smegmatis tends to stick to the tube and grow up the side.
Bacillus subtilus: sediment, organism settles to the bottom.
All organisms grown for 24-48 hrs except for M. smegmatis which was grown for 96 hrs.

  1. Correction: S. aureus is fine turbidity not flocculent. Flocculent would look more like flakes throughout the tube.....almost like a snow globe. Apologies.
