Biomass growth algae

Improvement of intraparticle mass transfer is the goal of some particle research efforts. One novel approach that has been recently tested is the co-immobilization of algae with bacteria the algae produced oxygen and the bacteria produced the desired product (Chevalier and de la Noue, 1988). Another method used microporous particles entrapped within alginate bead bioparticles to prevent excess biomass growth that could hinder intraparticle mass transfer (Seki et al., 1993). 

Marine algae, 4 species Isochrysis galbana, Skeletonema costatum, Thalassiosira pseudonana, Nitzchia angularis 1000 pg/L algae in 48 h in a biomass-dependent manner when cells increased from 100/mL to 2 million/mL. In absence of alga, up to 33% of fenvalerate added to glass containers was adsorbed to container walls in 48 h Insufficient to produce 50% growth inhibition in 96 h 2... 

At 75 pg As+5/L, growth and biomass in freshwater and marine algae was reduced. 

This work deals with the selection of strains of N2-fixing blue-green algae on the basis of biomass composition, productivity and tolerance to temperature and pH. Outdoor culture of the most adequate strains has been tested in order to derive optimal conditions for growth.
