Abstract

SERPA IBANEZ, Román Felipe  and  CALDERON RODRIGUEZ, Abelardo. Salt stress in three Dunaliella salina teod. strains in Peru. Ecol. apl. [online]. 2005, vol.4, n.1-2, pp.128-133. ISSN 1726-2216.

The effect of different levels of salinity ( 1.5M, 2.5M, 3.5M y 4.5M ) were studied on the growth and chlorophyll and carotenoid pigments contents in four Peruvian strains of Dunaliella salina. The results show a negative correlation between: a) The salinity and the cellular density at concentrations higher than 2.5M and b) The salinity and the pigments content ( mg/l ) . The strain FV-002 showed the higher pigment content both for carotenoids and for chlorophylls.

Keywords : salinity; carotenoids; chlorophylls; cellular density; Dunaliella.
