The present invention pertains to a method for the efficient production of carotenoids. In particular, the present invention is directed to a method for producing carotenoid and carotenoid-containing cells, especially astaxanthin and astaxanthin-containing cells, by generating mutant microorganisms belonging to the photoautotrophic algae of the Class Chlorophyceae and culturing same. The present invention further relates to methods of generating microorganisms producing high yields of carotenoids, in particular astaxanthin, products containing said microorganisms or said carotenoids, and the use of said carotenoids produced by the microorganisms according to the present invention and deposited mutant strains generated from said microorganisms.

The disclosed invention relates to a countercurrent process for the continuous esterification of C(fatty) acids with Cmonoalkanols, Cdi- or trialkanols or mixtures thereof in the liquid phase in the presence of heterogeneous catalysts in a preliminary reactor () and in a reaction column (), characterized in that the reaction column () is preceded by the preliminary reactor () and a separation unit () for the purpose of reducing the viscosity of the reaction mixture and removing the water of reaction from the system via a separation unit () to displace the reaction equilibrium before the reaction column (). A further aspect of the invention concerns feeding nitrogen in at the lowermost plate of the reaction column () in order to increase the vapor load in the lower part of the reaction column.
