Aquatic plants, Landoltia punctata, and Azolla filiculoides as bio-converters of wastewater to biofuel Academic Article Author's Version Abstract. Spirodela punctata (or Landoltia punctata, common name dotted duckmeat) is a species of duckweed . Plants. Crawford – dotted duckmeat Subordinate Taxa. Landoltia punctata plants take up nitrogen by both roots and fronds. Landoltia punctata (L. punctata), the most investigated representative of the Landoltia genus, showed high phytoremediation capacities along with high growth rates with an annual yield up to 39.2–55 t dw/ha-yr, which is higher than yields of the main bioenergy plants, such as switchgrass (5.2–26 t dw/ha-yr) and miscanthus (5.0–44 t dw/ha-yr) and woody plants, such as poplar (9–15 t dw/ha-yr) … Nutrient starvation and light deprivation effects on starch accumulation in Landoltia punctata cultivated on anaerobically digested dairy manure Kevin Kruger Dep.

Although previous studies indicated that L. punctata possessed the ability to accumulate a high content of starch (3%–75%) [21], the potential of duckweed as a novel bioenergy biomass was not recognized until recently [22]. Aquatic Plants, Landoltia punctata, and Azolla filiculoides as Bio-Converters of Wastewater to Biofuel. The aquatic plants, Azolla filiculoides, and Landoltia punctate, were used as complementing phytoremediators of wastewater containing high levels of phosphate, which simulates the effluents from textile, dyeing, and laundry detergent industries. D.H. Les & D.J. Here, pilot-scale comparisons of three duckweed species (Spirodela polyrhiza K1, Lemna minor K2 and Landoltia punctata K3) in monoculture and polyculture were investigated. 2. Landoltia duckweed is smaller than Spirodela polyrhiza , is more shoe-shaped, does not have a red dot on top, usually has only up to 4 roots, and sometimes has a red margin on the underneath of the leaves. those of the individual authors and contributors and not of the publisher and the editor(s). The aquatic plants, Azolla filiculoides, and Landoltia punctate, were used as complementing phytoremediators of wastewater containing high levels of phosphate, which simulates the effluents from textile, dyeing, and laundry detergent industries.
