| Tartalmi kivonat: | In this contribution the results of the following new investigations are presented: 1. Symmetry operations on the partially degraded and fragmented colony of fossil Botryococcus braunii. Quasi-crystalloid biopolymer skeleton and quasi-equivalent highly organized units are observed to be present within the same fragment. Four pentagon biopolymer units were selected from the bordering zone of the two kinds of symmetries and their structure was studied by rotation method. These observations have revealed different relationships between quasi-crystalloid and quasi-equivalent biopolymer system. 2. Colonies were partially dissolved with diluted diethylamine and merkaptoethanol for 30, 60, 90, 120 and 150 days. Then the fragmented organic remnants were investigated with TEM method. This experiment dissolved in the first place the molecular system sensu strictu. Different results were observed when the colonies were partially degraded with concentrated and dilute organic solvents (diethylamine, merkaptoethanol). |
