Two brown algae, Pelvetia canaliculata and Laminaria saccharina, from the higher and lower mediolittoral belts respectively, have been tested for their capacity to overcome high-light stress in water and in air (in both fully hydrated and desiccated

The influence of cell wall composition on the bacterial degradation of various constituents of green microalgae was examined during prolonged incubation in the dark with two ubiquitous, aerobic, heterotrophic bacteria ( Pseudomonas oleovorans and Fla

The influence of dodecylbenzene sulfonate (DBS) and Triton X-100 (TX-100) was examined on two species of Chlorella exhibiting conspicuous differences in cell wall composition. Chlorella emersonii has both a classical polysaccharidic wall and a thin t

Non-hydrolysable macromolecules were isolated from the marine green microalga Chlorella marina where they represent ca. 5% by weight of the dry biomass. Such resistant biomacromolecules, termed algaenans, were previously identified in numerous microa

The total carotenoid content during growth of the green alga Botryococcus braunii race B was related to culture volume, biomass dry weight, lipid-depleted biomass and N-content of lipid-depleted biomass. The relative abundance of individual carotenoi

Triazines and derivatives of phenylurea, which are often found in outdoor water samples, induce specific changes in the yield of thein-vivo chlorophyll α-fluorescence of PSII. These changes are correlated quantitatively with the concentration of the

Most Ordovician source rocks consist of accumulation of a colonial marine microorganism, Gloeocapsomorpha prisca (G. prisca) whose nature, ecology and affinity with extant organisms have been in dispute for years. Furthermore, recent studies have sho

The influence of SC 1058, a cinnolinyl compound recently shown to inhibit the formation of exines of pollen grains, was studied in the A and B races of Botryococcus braunii . A pronounced inhibition of the non-hydrolysable biopolymers (PRB A and PRB

Many green microalgae possess a thin trilaminar outer wall (TLS) with a very high resistance to chemical degradation. TLS are known to play an important protective role in living cells. They are also selectively preserved during fossilization and thu

New structures, termed ultralaminae, were recently observed by Transmission Electron Microscopy, usually in high amounts, in a number of kerogens from oil shales and source rocks. Morphological similarities were noted between ultralaminae and the thi
