Oxidation ponds have been used for many years for treatment of domestic wastewater. Nutrients and carbon dioxide produced by the decomposing organic wastes enhance the growth of unicellular algae which, in turn, provide oxygen for the bacterial decom

Three species of bivalve mollusc Crassostrea gigas (Thunberg), Ostrea edulis L., Tapes philippinarum (Adams and Reeve), one species of crustacean, Homarus americanus, and one species of macroscopic algae Gracilariopsis sjostedtii were grown in a pilo

A series of outdoor, continuous-flow seawater cultures (50 l; 0.23 m2) were used to investigate the effects of culture density (kg/m2), nutrient loading (total nitrogen input/day) with both NH4+N and NO3−N, and turnover rate ( flow rate cultu

The rhodophyte Gracilaria tikvahiae and the chlorophyte Ulva sp. were grown under three different nitrogen enrichment regimes producing plants of each species with three different concentrations of tissue nitrogen. Each was then digested in batch-mod

Four aquatic biomass species were anaerobically fermented to methane as part of an evaluation of these biomass as potential energy resources. Two freshwater weeds (Duckweed (Lemna sp.) and Hydrilla verticillata) and two marine algae (Gracilaria ceae

The macroalga Gracilaria tikvahiae (Rhodophyta) was used in a closed system of materials to study methane production and nitrogen recycling. Twenty liter carboys served as digesters. The performance of these digesters mirrors results obtained with tw

Nitrogen-starved plants of the red alga Gracilaria tikvahiae (McLachlan, 1979) assimilate ammonium-nitrogen very rapidly, doubling their total tissue nitrogen content in 8 h or less. Uptake of nitrate-nitrogen is less rapid. Ammonium uptake is initia

The increasing awareness that nitrogen is often a key nutrient controlling algal growth in coastal marine waters has led to a concerted effort to find ways to remove ammonia and nitrate from wastewaters. A novel approach to this problem involves the

Recently, considerable interest has developed concerning the use of biomass as an alternative fuel source. Among the possible substrates, marine plant biomass has frequently been mentioned, primarily due to the fact that such plants do not have compe

The floating freshwater macrophyte Eichhornia crassipes (water hyacinth) was fermented anaerobically to produce 0.4 1 of biogas/g volatile solids at 60% methane with a bioconversion efficiency of 47%. Both the liquid and solid digester residues were
