Photic volume in photobioreactors supporting ultrahigh population densities of the photoautotroph Spirulina platensis
Article Abstract:
The spectral absorption and scattering coefficients for algal suspensions in photobioreactors are studied experimentally. The photic zone and light penetration depth in the extremely dense algal suspensions are characterized via attenuation and spectral measurements. Results show that the absorption coefficient of the algal suspensions is strongly dependent on their physiological condition. The data also suggest a photosynthetic role for green light under specific conditions.

Biodegradation of phenols by the alga Ochromonas danica
Article Abstract:
The eukaryotic alga Ochromonas danica grows on phenol as the only carbon source in axenic culture, converting phenols to the respective catechols. These are subsequently degraded by the meta-cleavage pathway. [U-14C]phenol is totally degraded, with 65% of the isotope being converted to 14CO2, 15% remaining in aqueous solution and the rest in the biomass. Analysis of the biomass reveals that the protein, nucleic acid and lipid fractions have 14C.

Diversity and abundance of Bolidophyceae (Heterokonta) in two oceanic regions
Article Abstract:
Research was conducted to determine distribution of algal populations in the Pacific Ocean and the Mediterranean Sea. The data indicate that members of the new class Bolidophyceae constitute a minor component of the overall picoeukaryotic populations.
