Symmetry operations on the quasi-periodic biopolymer structures of the wall of Botryococcus braunii Kütz. I.
Using the two dimensional symmetry operations on the biopolymer structures of the partially degraded colonies of Botryococcus braunii isolated from Upper Pliocene oil shale from Pula, new data were obtained. Connected regular pentagons (biopolymer A and B) and one in oblique position (biopolymer C)...

| Tartalmi kivonat: | Using the two dimensional symmetry operations on the biopolymer structures of the partially degraded colonies of Botryococcus braunii isolated from Upper Pliocene oil shale from Pula, new data were obtained. Connected regular pentagons (biopolymer A and B) and one in oblique position (biopolymer C) were rotated with fivefold and tenfold primary rotation. The fivefold primary rotation resulted the quasi-crystalloid molecular structure of one globular biopolymer unit. At biopolymer C three globular units were observed in the TEM pictures, the fivefold rotation revealed the complete regular pentagon. A great number of secondary points of symmetry appeared, which may be useful for further symmetry operations. |
