Discussion Energy Fuel. It also showed the possibility of using chloroplast DNA data to elucidate those phylogenies which were not yet solved well by traditional methods even in plants other than duckweeds. Cellulosic biofuels feedstock is estimated to be over 1 billion dry tons per year in the United States which could replace 30% of current demand for transportation fuels. Genetics Analysis version 7.0) was used to generate maximum-parsimony and distance trees. In experiments where L. punctata treatment was followed by fresh L. punctata, PO4 concentration was reduced by 65%. This symbiotic relation leads to the fixation of 1.1 t/ha-yr of nitrogen, which is quite high than the fixation rate of nitrogen in legumes. The ability of Azolla to grow on wastewaters, along with their high productivity rate, makes it an attractive feedstock for the production of biofuels. Aquatic weeds have an exceptionally higher reproduction rates and are rich in cellulose and hemicellulose with a very low lignin content that makes them an efficient next generation biofuel crop. The ethanol production from Azolla filiculoides, 11.7 × 103 L/ha-year, is close to that from corn stover (13.3 × 103 L/ha-year), but higher than from miscanthus (2.3 × 103 L/ha-year) and woody plants, such as willow (0.3 × 103 L/ha-year) and poplar (1.3 × 103 L/ha-year). Growth of Azolla in contaminated water results in the removal of total phosphorous and nitrogen with the growth rate of 0.43 t P/ha-yr and 2.6 t N/ha-year, respectively. ; Stasinakis, A.S.; Aloupi, M.

Besides biomass production, starch accumulation is another key consideration for duckweed application in biofuel production. Shrimp survival was. 77–87. Duckweed, a fresh-water aquatic plant, is of interest to the scientific community because of its use in bioremediation, and its potential use as a biofuel. Higher levels of starch accumulation in leaves are usually correlated with a lower growth capacity. Results A. filiculoides and L. punctata can be used as a new generation of feedstock, which can treat different types of wastewater and represent renewable and sustainable feedstock for bioenergy production. Background Renewable biofuels, such as bioethanol, derived from bio-mass is considered to be the most promising alternative to petroleum liquid fuels. Using systematical screening, we determined that the highest biomass and starch percentage of duckweed was obtained after uniconazole application. In both cases, the hydrogen production rates increased exponentially between 12, and 24 h followed by the stationary phase at 24 h, wh, production of metabolites such as acetic acid and, terminated after 48 h.
