“…The study included a comparison of paddle wheels with Archimedes screws and propellers; they were all similar in power inputs. Foils placed into the pond to stimulate turbulence increased productivities (see also Laws et al, 1983Laws et al, ,1986Laws et al, ,1988. Productivities were generally lower than in prior studies by this group, about 20 g biomass ash free dry weight/m2/day, possibly due to high respiratory losses.…”

The global warming issue caused mainly by carbon dioxide (CO 2 ) has triggered various efforts to reduce excess amount of CO 2 emitted into the atmosphere. A viable option is to utilize biomass production potential of microalgal consortium in aquatic ecosystem that constantly requires CO 2 to perform photosynthesis. This study aims to provide scientific contributions to the development of environmental studies, particularly of using microalgal consortiums as carbon capture and storage (CCS) agent by engineering their culture conditions. A number of studies analyzing biological reduction of atmospheric CO 2 by using CO 2 absorption capability of terrestrial plants have been facing many difficulties. Compared to various terrestrial plants, microalgae are generally considered photosynthetically more efficient. Exploitation of microalgal capability has numerous advantages, including their faster regeneration time, ability to grow in less space than terrestrial plants, and because the cultivation of microalgae can be done on a small-scale or large-scale operation, under controlled conditions, and is independent to climatic changes. Taking into account long-term advantages, this study is a preliminary study which is expected to be able to provide information and feedback regarding integrated microalgal culture system that may lead to alternative solutions of ecofriendly and sustainable environmental management technology that are capable of mitigating environmental problems caused by CO 2 (as greenhouse gas) emissions. Hence, the results of this research could be implemented by building urban microalgal ponds in efforts to develop sustainable cities in terms of CO 2 emission reduction in urban areas.

“…The enhancement of photosynthesis by flashing light (both the rate and the efficiency) has been known for many years. Richmond and Vonshak (1978) and Laws et al (1983) reported increased growth rates when the stirring speeds of their mass cultures were doubled. They ascribed the increase to a more favorable dark/light cycle with increase turbulence.…”
