Interactions microalgues-bactéries en système expérimental bispécifique : effets sur la croissance de Dunaliella sp.
Provedor de dados: 5
Autores: Le Chevanton, Myriam.
The use of algae-bacteria mixed culture has been suggested to improve performance of industrial microalgae culture. The present study aims to investigate impact of selected bacteria on Dunaliella sp. growth. 97 bacteria strains were isolated from a variety of marine microalgae cultures. The diversity of strains revealed members of α-and γ-proteobacteria, Cytophaga-Flavobacterium-Bacteroides and grampositive. A two-phase approach was then implemented to select bacteria that improve Dunaliella sp. growth, using an original high-throughput experimental device. Although a majority of bacteria induced performance reduction for Dunaliella sp., some resulted in significant improvements. In nitrogenlimited batch culture, the Alteromonas sp. bacteria demonstrated a...
