Botryococcus braunii is a potential source of renewable energy due to high lipid yield and the ability of hydrocarbon excretion B. braunii 807/2 was successfully grown in outdoor paddle wheel driven raceway ponds for over 5 months. The growth of this alga in tubular photobioreactor (Biocoil) was also successful for up to a month, but was inhibited by high cell sticking to the coils. There was no significant difference in growth rate and biomass productivity between these two systems. The lipid productivity B. braunii culture in the open pond was 0.008 ± 0.004 g.L-1.day-1 at a specific growth r

Abstract:

Botryococcus braunii is a green alga with high long chain hydrocarbon content suitable as a source of biofuel. Due to its external hydrocarbon production, mass cultivation of B. braunii can potentially reduce biofuel production energy and water requirements. However, if the aim is to mass produce biofuel, growing any microalgae with the conventional liquid based cultivation systems are found to be currently not economically viable. The alternative cultivation method is solid growth (biofilm) that can reduce energy and costs associated with harvesting and dewatering process. In the present work

Abstract:

Microalgae are widely viewed as a potential source of renewable biofuels. Microalgae are highly productive and can be cultured in recycled water on margial or non-agricultural land. Despite their advantages, the industrial scale deployment of microalgae faces numerous challenges including relatively little knowledge of the algae themselves and the comparatively expensive infrastructures required for culture. The green microalga, Botryococcus braunii is particularly interesting because it synthesizes long-chain (C30- C40) hydrocarbons that can be converted to liquid fuel by hydrogenation and ca

Abstract:

As the human population and expectations of quality of life continue to increase, with it so does the demand for energy. Until recently, much of this energy has been obtained through the combustion of fossil fuels. As these natural carbon sinks are consumed for energy and transportation, carbon which was once sequestered in the earth’s crust is being released into the atmosphere at an unsustainable rate. Current CO2 levels are the highest on record which has resulted in a decrease in ocean pH having devastating effects on marine ecology. Further high CO2 levels combined with elevated levels of

Dissertação de mest., Biologia Marinha (Ecologia e Conservação Marinha), Faculdade de Ciências e Tecnologia, Univ. do Algarve, 2011<br>Os peixes da família Myctophidae são a principal alternativa ao krill Euphausia superba, a base da típica cadeia trófica antárctica. No Oceano Antárctico, estima-se uma biomassa de mictofídeos entre 70 e 200 milhões de toneladas. Devido às migrações verticais diárias que efectuam entre a superfície e os 1000 m de profundidade, os mictofídeos fornecem energia aos predadores de topo das camadas superficiais, tais como Dissostichus eleginoides (bacalhau-do-Antárct

碩士<br>國立中興大學<br>昆蟲學系所<br>100<br>The frog fly (Phumosia indica Surcouf, 1914) parasitoids the foam nest of tree frog (Polypedates braueri Vogt, 1911) which is a wide distributed specie in Taiwan, and the interaction between these two species becomes an issue of population genetics, phylogeography, and co-evolution. In this study, Taiwan is divided into northern region, middle region, southern region, and eastern region according to previous studies of amphibian in Taiwan. To reveal evolutionary scenarios of P. indica and P. braueri, the foam nest of the P. braueri were collected in these region

Abstract:

Dissertação de mestrado, Engenharia do Ambiente, Faculdade de Ciências e Tecnologia, Universidade do Algarve, 2016<br>With the increase in greenhouse gases (GHG) concentrations on the atmosphere, and the problems associated with it, the interest in the development of microalgae-derived biofuels has grown significantly in recent years. Microalgal biomass presents several advantages over feedstocks commonly used for the production of biofuels. However, current production costs are still too high and uncompetitive when compared to fossil fuels. In order to reduce the production costs of microalga

Abstract:

Algal biofuel has been shown to have great potential to solve the World’s sustainable energy crisis but technologies for large-scale cultivation are still elusive. While photobioreactors meet very high value algal products there is still no technology for producing algae by the millions of tons. Flooded paddy lands of India offer excellent opportunities for co-cultivation of algae with paddy crop provided it meets various sustainability criteria, not to mention very low cost options. This research examines sustainability, technology and climate change challenges to this above concept termed “A
