Two phase microalgae growth in the open system for enhanced lipid productivity

Das, Probir; Aziz, Siti Sarah; Obbard, Jeffrey Philip - In: Renewable Energy 36 (2011) 9, pp. 2524-2528

Enhancement of the intracellular lipid content of Nannochloropsis sp. was first studied in a two phase culture system i.e. 7 days in photoautotrophic mode followed by 3 days in mixotrophic mode in the presence of either glycerol, glucose and sucrose in small scale closed system. During the first...

Simulation of the redistribution and fate of contaminants from soil-injected animal slurry

Amin, M.G. Mostofa; Šimůnek, Jirka; Lægdsmand, Mette - In: Agricultural Water Management 131 (2014) C, pp. 17-29

Spreading of contaminants from land-applied animal slurry may create hazard for both soil and water environments. Both the leaching and persistence of the contaminants is controlled by the redistribution of the contaminants immediately after application, while the redistribution is influenced by...
