Available in PDF, EPUB and Kindle. Book excerpt: A highly instrumented photosynthetic gas exchange system was designed, fabricated and tested for handling the carbon dioxide output and supplying the oxygen requirements of one man. The system designed consists of three major components: (1) a multi-pass light chamber containing thirty-six 96-inch 'Power Groove' fluorescent lamps, (2) a counter-current gas contacting tower, and (3) an instrumentation console for controlling and recording the important parameters. In addition, a centrifuge is provided for the harvesting of algae. Based on the growth rate of the algae, the study demonstrated that this system has the capability of supporting one man.

Available in PDF, EPUB and Kindle. Book excerpt: A continuous culture system was designed to study the use of solar energy for algal growth and photosynthetic gas exchange. Design parameters were calculated to support algal growth and photosynthesis during peak sunlight at a rate sufficient to provide respiratory support for one man. The unique feature of the system was the facility for orienting the panels to face and track the sun. Instrumentation was provided for monitoring the important variables affecting algal growth. Testing with the system spanned a three-year period and two geographical locations. Experimental results provided data on the operating parameters of a large solar-illuminated algal culture system and approximately confirmed the original calculations for algal production rate.

Available in PDF, EPUB and Kindle. Book excerpt: The alga, Chlorella pyrenoidosa 71105, was grown as a continuously diluted culture in a 12-liter, engineering research photosynthetic gas exchanger. In this device, the algal culture surrounded a cylindrical light source having a surface area of 0.1 sq. m. Environmental conditions were kept constant by automatic control. Optimal conditions for algal growth in the gas exchanger were determined experimentally to be: 35,000 foot candles, 2.5% CO2, 0.2% packed cell volume, 0.114 hr to the minus one power dilution factor, and 39 C. Under these conditions, maximum algae yield was 0.754 gm/hr (dry wt) and maximum oxygen production was 1.25 gm/hr, or 0.03 kg per day. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The algae are a diverse group of organisms with forms that range in size from less than a micron in diameter to over ten meters in length. Small {laquo} 1 JLm diam) unicellular forms dominate the open waters of the oceans and large lakes. Large multicellular forms often form a large component of the autotrophic biomass of shallow waters at the periphery of lakes and oceans but have also been found on seamounts in clear open ocean waters at depths up to several hundred meters (Littler and Littler, 1985). Phytoplankton in the sea probably account for more than 50% of global photosynthesis, although there is considerable uncertainty about this estimate. In addition, many symbiotic associations between unicellu lar algae and heterotrophic or autotrophic organisms have been identi fied, and algae can be found in a diverse range of terrestrial environ ments, ranging from polar to desert regions. The most important common biochemical attribute that unites the algae is their ability to split water, producing molecular oxygen during photosynthesis and concomi tantly assimilating carbon dioxide. This attribute is shared with the terres trial plants, cyanobacteria and chloroxybacteria. Although vascular plants are excluded from this review, we employ a broad definition of algae that includes the photosynthetic, oxygenic procaryotes. Measurements of gas exchange are fundamental to most biochemical, physiological and ecological investigations of the algae.

Download or read book Design Study of Gravity independent Photosynthetic Gas Exchanger written by Robert G. Newland and published by . This book was released on 1963 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Photosynthetic Gas Exchanger System utilizing a strain of Chlorella vulgaris algae has been designed and fabricated, and tested for periods up to fourteen days. A maximum oxygen evolution of 1.97 liters per day and carbon dioxide absorption of 1.44 liters per day was achieved during the testing. This capability is provided in a completely closed system which can operate at atmospheric pressures between 7.5 psia and 14.7 psia. The design is capable of gravity independent operation and is adaptable to automatic and semi-automatic operation by regulation of illumination intensity on the algae in response to surrounding chamber oxygen level. The design of the system provides for continuous harvesting of algal cells and maintenance of an adequate nutrient level in the algal solution. The design utilizes a non-wettable, open pore membrane for diffusion of oxygen out of the algal solution and carbon dioxide into solution by partial pressure differences. At the same time, the membrane retains the algal solution within the Photosynthetic Gas Exchanger. The peak power required by the system is 172 watts. The system is mounted on a structure which illustrates a possible subsequent design for flight application. A follow-on program is recommended to perform further development tests to increase the performance of the system and to adapt the system for testing in an orbiting satellite.

This book was released on 2020-06-03 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algae, including cyanobacteria, are in the spotlight today for a number of reasons; firstly it has become abundantly clear over recent years that algae have been neglected in terms of basic research and that knowledge gap is being rapidly closed with the establishment of some surprising discoveries, such as the presence of Near-Infra-Red-Absorbing cyanobacteria and a wealth of natural products; secondly molecular approaches have provided a wealth of approaches to genetically modify algae and produce value-added products; thirdly it has become clear just how important, marine phytoplankton is to global carbon capture and the production of food globally; and fourthly, it has also become clear that algae present unparalleled opportunities to generate biofuels in a sustainable and non-polluting way. This volume presents 15 chapters by world experts on their subjects, ranging from reviews of algal diversity and genetics to in-depth reviews of special algal groups such as diatoms (which account for over 30% of marine carbon capture). Other chapters chart the ways in which this carbon capture occurs or how there are a multiplicity of ways in which algae intercept sun light and deploy this energy for carbon capture. A fascinating aspect here is the way in which sun light is harvested. A special chapter is devoted to the very recent and exciting possibility that algae use coherent light energy transformation to enhance the efficiency of light capture, an aspect of quantum physics that has implications for future developments at several levels and a variety of industries. Just how and why algae use Chlorophyll a as the major light capture pigment is discussed in several chapters. However, attention is also given to those cyanobacteria, which have been found to use the special Near-Infra Red absorbing chlorophylls mentioned above. And attention is also given to those algae that employ phycobiliproteins to fill in the “green window”, i.e., the spectral region from 400 – 650 nm, which is not efficiently covered by chlorophyll and carotenoid pigments. Photoinhibition and photoprotection is the subject area of several chapters and one which it is essential to understand a we work towards greater efficiency of algal photosynthesis. A final chapter is devoted to understanding the molecular basis for coral bleaching, a much-neglected area that is essential in trying to come up with solutions to this very worrying phenomenon, caused by global warming and ocean acidification. This is a book for research scientists, environmentalists, planners in a range of areas including those of marine resources, nutrient control and pollution of water bodies and that growing body of concerned citizens interested in controlling carbon emissions and global warming. Special attention has been given to generating a set of articles that will be read by university students, informed laymen and all those whose wish to understand the rapid changes that have come about in our knowledge of algae over the past decade.
