title: Variability of cultural and morphological traits of Dunaliella salina Teod. from different habitats
abstract: Deficiency of nitrogen and phosphorus induced beta-carotene accumulation in the cells of 35 clonal cultures of D.&#13;\nsalina isolated from 6 habitats in Ukraine and 1 in Russia. Nitrate and phosphate re-supplied into the medium&#13;\ndecreased cellular beta-carotene content and cell size. Repeated passage into the medium without nutrients&#13;\nrecovered inducible beta-carotene level; the dimensional characteristics of the cells recovered partly. Isolates from&#13;\ndifferent habitats (except
