Abstract
Bottles of medium were inoculated with both strains of Chromatiaceae and Chlorobiaceae (mixed cultures) and immersed at different depths in the marine coastal waters of the Marseilles basin (France). After development, the in vivo absorption characteristics of the cells show the effect of daylight penetration on selective growth of phototrophic sulfur bacteria. With depth, sunlight selects Chlorobiaceae rich in brown carotenoid pigments to the detriment of Chromatiaceae.This publication has 0 references indexed in Scilit:
