Starch-rich biomass can be produced by several methods of starch induction. In <br>the present project the effects of nutrient deficiency (phosphate, nitrate and sulphate) on starch accumulation were investigated in 21 <br>clones (strains) of duckweeds covering 11 species and all 5 genera of the duckweed family encompassing a wide geographic area. The <br>magnitude of change in the starch content after treatment with nutrient deficient medium varied widely within the genera, the different <br>species and different clones of the same species. Highest values, between 40 and 50 %, of starch on dry weight basis of the whole <br>plant biomass were obtained after two weeks of application of phosphate- or nitrogen-lacking nutrient media whereas sulphate deficiency <br>showed minor effects. It is concluded that various clones of the species Landoltia punctata, Lemna minor, and Spirodela intermedia proved <br>to be promising candidates for starch rich biomass production.</p> ER -
