The evolution of multicellularity is an example of an evolutionary transition in individuality, in which a group of lower-level biological units (cells, in this case) emerges as a higher-level unit (the multicellular organism) with its own fitness, heritability and individuality. The volvocine green algae are a model system for the transition to multicellularity and for the evolution of cellular differentiation. Some of the developmental changes that collectively make up this transition have occ...

The objective of our design was to create a chemical plant that uses cultivated algae grown on site in order to produce a biofuel as an alternative energy source. Currently there is a push for sustainable energy sources and biologically produced fuels are attractive due to their near net-zero carbon emissions. Algae provides a valuable source of energy due to its growth rate and sustainability. Chemical engineering principles were utilized in design; a supercritical carbon dioxide extractor for ...

<p> After primary and secondary recovery there is still oil remaining in the reservoir, so tertiary recovery is introduced. This is also known as EOR. Enhanced oil recovery has been widely used with different types of polymers. Algae polymer is a new development with its own advantages and limitations. In order to discover the economic potential of algae polymer, this paper focuses on the recovery factor of algae polymer and compares it with other published results.</p>

Microalgae are one of the oldest types of lifeforms on this planet and dead algae are one source for the oil that we extract from the ground. This oil has a major part in the technology advances of humanity, to levels unimaginable not long ago. Unfortunately, this oil is one of the major reasons for the global warming and other environmental issues caused by humans. Therefore, much effort is made on new technologies to decrease the use of fossil oil and other fossil material in favor for so call...

Climate change is progressing rapidly and is causing shifts in ecosystem function, species distributions, biodiversity, and abundances worldwide. In this thesis, I explore the physiological and biomechanical responses of red algae in multiple life history stages to climate change. In Chapter 1, I introduce the looming threat of climate change, and some of the forces driving ocean acidification. I introduce my study system and my study species: rocky intertidal ecosystems and articulated corallin...

Routine monitoring of algae in inland waters in southern Africa is a critical element in assessing the efficacy of eutrophication management options. Several authors have indicated that single point samples are not necessarily representative of conditions throughout the water body and some have suggested remote sensing as a means of overcoming this problem. Remote sensing of algae normally involves deriving the empirical relationship between radiance detected at a sensor, and contact sensed chlo...

Phytohormone auxin plays an important role in regulating plant development. Directional (polar) cell-to-cell auxin transport creates auxin gradients within plant tissues, which trigger a specific developmental response. The vast majority of available data concerns angiosperms. Lower land plants have been much less explored in this regard, but the important auxin-related mechanisms (including polar auxin transport) are already present in mosses. To uncover the origins of auxin action, one must fo...

The goal of the project is to design a plant that is capable of converting an algae feedstock into compressed natural gas (CNG). This product is intended to be sold as a green replacement for CNG produced using traditional methods. In addition to CNG, hydrogen gas is produced; this product will be sold as a biofuel as well. The CNG produced in this process is created by gasifying algae in supercritical water and then reacting the algal matter over an Ru/C catalyst. The resulting gas is then puri...

Ice algae are an important component of the carbon cycle in the Arctic, and can therefore have an impact on climate. I investigate the dynamics of an ice algae bloom by coupling an algae-nutrient model [Lavoie et al., 2005] with a thermodynamic sea ice model [Huwald et al., 2005]. The sea ice component is a more sophisticated model than what has been used in past Arctic ice algae model studies. To validate the model, I simulate an algal bloom at the base of the ice over a season a...

The culture of coccolithophorid algae is an attractive option for sequestration or recycling of CO2 as they can fix carbon by photosynthesis as well as in calcium carbonate scales known as coccoliths. They also produce high amounts of lipids which have a potential application as a renewable fuel. Five species of coccolithophorids (Pleurochrysis carterae, CCMP647, Pleurochrysis sp. CCMP1211, Gephyrocapsa oceanica CS-335/2, Emiliania huxleyi CCMP371, and Emiliania huxleyi CS-369) were screened...

This project involved designing a process that converts algae into compressed natural gas (CNG). The algae enter the process in a water slurry at 2.5% algae by mass. The algae are then converted into methane and other gases at supercritical conditions in a reactor. The gas mixture is then purified by removing the carbon dioxide and hydrogen gases. The sellable products this process produces are CNG and hydrogen. In addition, the carbon dioxide and salts are recycled back to the algae farms. This...

It is the purpose of this study to ascertain what environmental factors might cause morphological changes exhibited by certain algae, also to determine if this variation in morphology is vegetative, reproductive, or artifactual in nature, and to show what effects these changes in morpohology might have on classification of the organisms in question.

The evolution of somatic cells is a key aspect in the evolution of single to multicellular life forms. Our model is based on an empirically tested model of the growth of unicellular Chlamydomonas algae and a suggestion by Koufopanou (1994) that the basic mechanism underlying Chlamydomonas growth and reproduction may better explain the diversity of more complex volvocine algae morphologies. Six strains of Pleodorina starrii investigated in terms of the parameters of the model, yielded data for th...

This thesis reports the rheological properties of algae slurries as a function of cell concentration for three microalgae species: Nannochloris sp.,Chlorella vulgaris, and Phaeodactylum tricornutum. Rheological properties ofalgae slurries have a direct impact on the agitation and pumping power requirements as well as process design for producing algal biofuels. This study measures the rheological properties of eight diff erent concentrations of each species ranging from 0.5 to 80 kg dry biomass/...

Texas – the energy center of the world – is emerging as a pioneer in algae biodiesel research and production. There are a number of reasons for this. Texas is the largest emitter of CO₂ in the country, and efforts are being made to reduce the state's dependence on fossil fuels. Also, algae – robust and promising organisms – need non-arable land, lots of sunlight and brackish/waste water, along with CO₂. Texas has all of these in abundance, plus universities and algae start-ups that are doing cru...

Algae offer as much as 30 times greater biomass productivity than terrestrial plants, and are able to fix carbon and convert it into a number of interesting products. The numerous challenges in algae production and use extend across the entire process chain. They include the selection of suitable algal phyla, cultivation (which takes place either in open ponds or in closed systems), extraction of the biomass from the suspension, through to optimal use of the obtained biomass. The basic suitabili...
