The ecological position of micro-algae at the base of the aquatic food web makes them critical components of aquatic ecosystems. Their short generation time also makes them useful biological indicators because they respond quickly to changes in environmental condition, enabling timely identification and assessment of water quality changes. The inclusion of micro-algae as indicators in water resource regulation and management in South Africa has started recently, their more extensive use in biomo...

The presence of huge quantities of nutrients in water bodies heavily promotes the growth of algae. Excess nitrogen and phosphorus in discharged wastewaters can lead to downstream eutrophication thereby damaging the ecosystem. Algae bioremediation involves the use of live algae in the removal of excess dissolved nutrients from wastewater and subsequently diminish the pollution load. It is an alternative economical and sustainable way of treating sewage wastewater compared to conventional treatmen...

As evidence piles up indicating that anthropogenic CO₂ emissions are affecting the world's climate with potentially devastating results for its population, more attention is being directed towards means to reduce the quantities of CO₂ being released. The production of energy through the burning of fossil fuels is the primary cause of these emissions, but is also vital to our current lifestyle and even survival. As such, it is essential that we develop reliable and economically viable renewable...

A novel electrode was constructed and tested in a bio-battery. This configuration consisted of a composite electrode with immobilized bacteria (Escherichia coli K-12) in the anode and a composite electrode with immobilized Carbon Nanoparticles (CNP) and algae (Chlorella vulgaris/Scenedesmus sp.) suspended in the cathode. The composite electrode consisted of three parts: a 304L stainless steel mesh base, an electro-polymerized layer of pyrrole, and an electro-polymerized layer of methylene blue. ...

Nitrogen removal from wastewater by algae provides the additional benefit of producing lipids for biofuel and biomass for anaerobic digestion. As ammonium is the renewable form of nitrogen produced during anaerobic digestion and one of the main nitrogen sources associated with wastewater, experiments focused on the optimization of growth and lipid production when grown on ammonium were evaluated. Scenedesmus sp. 131 and Kirchneriella sp. 92 were grown in a 14:10 light/dark cycle on ammonium, nit...

Climate variability in the North Atlantic has been linked in part to the North Atlantic Oscillation (NAO). The NAO influences marine ecosystems in the northwestern Atlantic and the transport variability of the cold Labrador Current (LC). Understanding historic patterns and predicting future changes in LC transport require long-term and high-resolution climate records that are not available from instrumental data sets. This thesis presents the first century-scale sea surface temperature (SST)reco...

Ecological factors influencing the distribution, survival and growth across wave exposures of different life stages of some intertidal habitat-forming fucoid algae in southern New Zealand and Oregon were examined. Transect and quadrat sampling in southern New Zealand showed changes in patterns of habitat-forming intertidal algae across wave-exposures. Biomass and species richness across exposures varied greatly and was concentrated in the lower tidal zone. On wave-exposed platforms lower tidal ...

Barley protoplasts were shown to be a suitable experimental system for studies on the relative maximum during the decay of luminescence observed in most photosynthetic systems after excitation with far red light and in the presence of O2. The far red induced relative luminescence maximum was shown to be a result of three coinciding events: *Randomization of the S-states of the water splitting system during illumination with far red light. *Extreme oxidation of the PSII acceptor side after excita...

Biofuel production from microalgal biomass offers a clean and sustainable liquid fuel alternative to fossil fuels. In addition, algae cultivation is advantageous over traditional biofuel feedstocks as (i) it does not compete with food production, (ii) it potentially has a much greater areal productivity, (iii) it does not require arable land, and (iv) it can use marginal sources of water not suitable for irrigation or drinking. However, current algae cultivation technologies suffer from (i) low ...

Blue-green algae, historically consumed as a food source in certain native cultures, has more recently been promoted as a nutritional supplement for the general public. Several claims have been made regarding the consumption of blue-green algae. Such claims range from increased physical and mental energy to the treatment of neurological disorders and the enhancement of the immune system. / In order to determine whether the species of blue-green algae Aphanizomenon flos-aqua (AFA) has effects on ...

Three sampling methods were used to determine th biomass (chlorophyll ' a' content and algal biovolume) of sediment-associated algae (SAA = epipelon + plocon) at three sites in Delta Marsh, Canada during a two-year period. I hypothesized that the importance of SAA in wetlands has been substantially underestimated due to sampling bias of the standard lens-paper trapping method towards only motile constituents of the assemblage. In addition to the lens paper method, SAA biomass was measured in i...

Common Carp, (Cyprinus carpio), have long been associated with the degradation of wetlands worldwide. Through their feeding activities they resuspend sediments leading to reductions in the abundance and diversity of submerged macrophytes, and the alteration of water chemistry which can lead to the phytoplankton-dominated state. This study took in Delta Marsh, a freshwater coastal wetland of Lake Manitoba, in Manitoba, Canada. It was the second part of a four-year study in which baseline data wer...

Selenium (Se) is a micronutrient, yet elevated Se can be toxic to aquatic organisms. The range of Se concentrations within which Se uptake goes from insufficient to toxic is very narrow. It is thus important to understand the Se biogeochemical cycle in aquatic systems. In this thesis, the study focuses on changes in Se speciation during uptake by green algae. An optimized method was adopted to quantify and speciate Se in water using flow-injection atomic fluorescence spectroscopy coupled with hi...

As algae-derived biofuel is a promising renewable energy source, it is well-established that micro-algae have the potential to make a significant contribution to transportation fuel demand. Although it has many advantages including high areal productivity, there are many negative factors. One of these factors is the predation of algae by amoebas, protozoans, ciliates and rotifers, particularly in open pond systems. For example, the rotifer Brachionus plicatilis, is able to eat as much as 12,000 ...

Copper ore was extracted from Britannia Mine, British Columbia, Canada, from 1902 until the mine ceased operations in 1974. Rain, snowmelt and groundwater now percolate through the mine tunnels, producing an acidic solution of dissolved metals known as Acid Mine Drainage (AMD). A portion of the AMD from the mine flows into Britannia Creek, which in turn flows into Howe Sound, 50 km north of Vancouver, B.C. This study examined the effects of this effluent on the distribution of intertidal ma...

Intertidal macroalgae endure stresses associated with submerged and emerged conditions on a daily basis. Differences in physiology at high tide, low tide, and during recovery underlie spatial separation of species along the shore. Tidepools provide refugia from physical stresses associated with the low tide, and species with low stress tolerance may be restricted to these habitats. Species that survive emergence employ physiological and morphological strategies to survive exposure to pseudo-ter...

This study examines the relative contribution of algae and vascular plant litter to the food chains of freshwater marshes. Twelve enclosures (5 m diam.) were deployed in a nutrient-poor marsh of the Interlake region of Manitoba. Algae levels in six of the enclosures were increased by fertilizing the water column. In addition, the hardstem bulrush (Scirpus lacustris glaucus (Sm.) Hartm) litter present was replaced with a non-nutritive artificial substrate in half of the fertilized and unfertilize...

Total phosphorus concentrations in the open waters of the Laurentian Great Lakes are currently at or beneath target concentrations set by international agreement. Despite the success of phosphorus loading controls in remediating nearshore eutrophication problems in the past, nuisance growth of Cladophora has recently returned to the lower Great Lakes. This thesis examines soluble reactive phosphorus (SRP) in a northwestern segment of Lake Ontario to assess whether allochthonous or autochthonou...

Large-scale culturing of algae with the aim of production of economically valuable substances is a growing industrial sector. A common problem of such industrial algae cultures is that they are prone to suffer from fungal infections causing growth inhibition of the algae and reduced production of the target substances. Having sensitive and target specific methods for the early detection of these infections are of great economic importance since in later stages infections may be very hard to trea...

Energy shortfall and air pollution are some of the challenges the human kind is facing today. Fossil fuel is still the most widely used fuel, which is a non-renewable resource, increasing excess carbon dioxide into the air. To overcome these issues, and reduce the carbon footprint, a greater development of renewable energy from green and natural resources is required. Compared to fossil energy, renewable energy has the benefit to reduce greenhouse gas emissions. There are different solutions ava...
