L'amidon et le glycogène définissent les deux polysaccharides de réserve les plus répandus dans le monde vivant. L'apparition de l'amidon chez les eucaryotes coïncide avec un événement d'endosymbiose unique qui s'est déroulé il y a 1,6 milliards d'années entre une cyanobactérie et un eucaryote primitif. De cet événement sont apparues trois lignées photosynthétiques : les Chloroplastida (plantes terrestres et algues vertes), les Rhodophyceae (algues rouges et organismes qui en sont dérivés par en...

Today 88 % of the world energy comes from fossil fuels. Greenhouse gas emissions are increasing and the fossil fuels energy sources will decrease at some point. Other alternatives must be found, to substitute and lower the usage of fossil fuels. Biogas is one of these other options. It is a versatile fossil free fuel that can be used for heat, power and fuel for vehicles. Many different substrates have been used for biogas production over the years, and now algae are examined as a substrate. Alg...

A mutualistic symbiosis exists between the alga Sargassum spp. and two shrimp species, L. tenuicornis and L. fucorum. But little is known about how the shrimp locate their host alga. Both visual and chemical cues are potentially available. Visual cues would be presumably restricted at night but chemical cues are potentially available continuously. Additionally, a previous study has looked at both cue variables with results that are mixed. This current research elaborates on the previous study in...

The goal of this study was to determine the significance of dissolved inorganic nitrogen (DIN) and dissolved organic nitrogen (DON) to harmful phytoplankton. Two regions that experience frequent and persistent harmful algal blooms (HABs) were examined, the Eastern Gulf of Mexico and York River, Virginia. Nitrogen uptake by harmful algae in these regions was examined using a combination of stable isotopic (15N) tracer techniques and nutrient bioassays. In the Eastern Gulf of Mexico, kinetic param...

The growth of a locally isolated strain of green algae, Chlorella sp., selected for its promise as a biodiesel feedstock, was studied in wastewater effluent from the municipal wastewater treatment plant in Tallahassee FL. Nutrient concentration and microbial community composition within the effluent were profiled at monthly intervals. Adequate nutrients for algal cultivation were observed along with a dynamic microbial community of zooplankton, green algae, diatoms, and a bacterial community tha...

Across the world, industrialization and the consequent emergence of economies reliant on fossil fuels have inevitably resulted in the adverse condition of atmospheric warming known as the greenhouse effect. Anthropogenic CO2 has been identified as one of the major causes. This research focuses on investigating the possibility of exploiting the natural photosynthetic process in fresh-water South African microalgae in order to reduce CO2 emissions, and in this way to create a more benign environme...

The fitness of any evolutionary unit can be understood in terms of its two basic components: fecundity and viability. The trade-offs between these fitness components drive the evolution of a variety of life-history traits in extant multicellular lineages. Here, I show evidence that the evolution of germ-soma separation and the emergence of individuality at a higher level during the unicellular-multicellular transition are also consequences of these trade-offs. The transition from unicellular to ...

This report evaluates the current economic outlook of producing algal biofuels as a potential replacement for fossil fuels. The proposed design incorporates two new technologies: hydrothermal liquefaction and catalytic hydrothermal gasification. Both of these technologies provide significant advantages over other dewatering, extraction, and residual biomass processing methods that are typically considered in past models. The design also accounts for the maximal recycle of resources in the system...

Gold mine tailings material facilities are characterized by sparse vegetation and an abundance of dust. Mine tailings facilities are examples of extreme geotechnical and geochemical conditions which make it almost impossible for higher plants to establish and grow without rehabilitation intervention. In most cases higher plants such as grasses and trees are the focus areas for rehabilitation, but, having a look at something a little smaller such as biological crusts, it is seen that these micro-...

To test the assumption that there is no spatial structure in small-scale recruitment variability of rocky shore mussels, we examined spatial dependence in the distribution of density of recruits (late plantigrades: 0.5 to 3.5 mm; larger recruits: 3.5 to 10 mm) and adults of the brown mussel Perna perna within local scales (30 lags ranging between 0.35 and 10.5 m) in mid- and upper mussel beds. Spatial heterogeneity was estimated by analyzing scaling properties of semivariograms using a fractal a...

The increasing pollution of the aquatic environment by cadmium is a potentially severe problem and techniques are needed to document the effect of the metal. To investigate the flux of this metal through a laboratory food chain, algae were grown in various cadmium concentrations for subsequent use as contaminated food for mussels. The results showed that in order to make valid deductions, more information about chemical mechanisms and background ecophysiological data is needed, otherwise accumul...

Algae are the most common primary producers in stream ecosystems, contributing as much as 80 % of the total primary production. The production of these ecosystems is strongly influenced by the terrestrial habitats, which are in turn likely to be altered by climate change. In arctic ecosystems, where the effects of climate may be most pronounced, there are important unknowns about how abiotic factors such as light, temperature, nutrients, flow regimes interact to influence stream productivity. Th...

Since many approaches to dealing with algal blooms are inefficient, expensive, or harmful, it was concluded that a biologically-synthesized chemical agent, specifically inhibitory to pre-bloom algal cells, might prove helpful in controlling algal blooms. Fungi were chosen as the biological entities to investigate for such a chemical.

This study had a three-fold purpose. First, it was decided to determine if algae and protozoa were emitted to the air at the Denton sewage treatment plant. The information obtained could be of future importance in the fields of algal and protozoan ecology and public health. Second, it was decided to make a survey of the airborne bacteria at this plant. Some researchers have described bacterial air contamination at similar sewage treatment plants, but the one in Denton has not been studied. Third...

Complex mixtures of biologically active pharmaceutical residues continuously enter aquatic environments via wastewater, where it can affect species through preserved human drug targets or cause unexpected effects in non-target species. Benzodiazepines and antihistamines are two highly consumed groups of pharmaceuticals that have been shown to bioconcentrate in aquatic organisms and induce behavioural alterations affecting individual fitness. Few studies have investigated bioaccumulation and poss...

Integrated algae pond systems (IAPS) combine the use of anaerobic and aerobic bioprocesses to effect wastewater treatment. Although, IAPS as a technology process offers many advantages including efficient and simultaneous N and P removal, no requirement for additional chemicals, O2 generation, CO2 mitigation, and a biomass with potential for valorization, a lack of technological advancement and the need for large land area, has limited the reach of this technology at industrial scale. In mitigat...

Background: The volvocine lineage, containing unicellular Chlamydomonas reinhardtii and differentiated multicellular Volvox carteri, is a powerful model for comparative studies aiming at understanding emergence of multicellularity. Tetrabaena socialis is the simplest multicellular volvocine alga and belongs to the family Tetrabaenaceae that is sister to more complex multicellular volvocine families, Goniaceae and Volvocaceae. Thus, T. socialis is a key species to elucidate the initial steps in t...

A study of the red algal order Gelidiales in British Columbia and northern Washington was conducted. Gelidiales are represented in the study area by four species, Gelidium coulteri, G. purpurascens, G. vagum and Pterocladia caloglossoides, and a key to identify the taxa is provided. Earlier reports of G. crinale, G. pusillum, G. robustum and G. sinicola from British Columbia and northern Washington have been shown to be misidentifications of the other taxa and are excluded from the flora. The oc...

Kootenay Lake receives high phosphorus loads to its south end and low phosphorus loads to its north end. These loading differences, combined with the lake's 105 km long fjord morphology, should result in a regional trophic gradient in the lake. I studied attached algae to assess how well they supplemented nutrient data in providing a more accurate measure of regional water quality differences. Algal abundance, phosphorus storage, production, species composition and distribution were measured at ...

Coralline algae are important components of the coastal marine ecosystem, making it crucial to understand influences on their production and their growth rate in general. A few attempts have been made to quantify coralline growth rate using various methods, however since they have been reported to be slow growers it is difficult to quantify their growth rate accurately. Calcofluor white is an optical brightener that can be used to stain cell walls of plants and has been used to stain articulated...
