Extracellular calcification of Braarudosphaera bigelowii deduced from electron microscopic observations of cell surface structure and elemental composition of pentaliths
B. bigelowii has a haptonema, and can use it for adhesion to external substrates.
•
B. bigelowii has a unique cell surface structure called pentalith-substrate.
•
Pentalith-substrate and organic layers probably play some roles in calcification.
•
Pentalith calcification probably takes place extracellularly
•
Pentaliths contain relatively higher amounts of Mg than typical heterococcoliths.
