Organism Bacteria Spiroplasma melliferum

Method Cryoelectron tomography (CET) and Scaling index based segmentation (SIBS)
Comments "When taking into consideration that the segmented membrane structure is incomplete due to the missing wedge (only ~70% of the total cell surface is clearly visualized), [researchers] estimate that approximately 15% (29/275?100?100/70) of the ribosomes are membrane-associated in [researchers'] case."
