Fine structure of elongate polyhedral bodies (carboxysomes) in two Oscillatoria (Cyanophyceae) isolates.
Polyhedral bodies (carboxysomes) in two Oscillatoria isolates were of two morphological forms. Some were typical polygonal bodies with many straight sides and were approximately 0.2 micron in diameter. Most of the bodies in these isolates were elongate being up to 2.6 microns in length, 33 nm in width and approximately 0.1 micron in depth. Some of the bodies were polygonal with an elongate extension. All of the bodies were limited by a membrane monolayer of approximately 20 A. The function of polyhedral bodies (carboxysomes) is discussed in relation to their observed morphology.
