Special emphasis was placed on elucidating the principles underlying efficient utilization of high photon flux density for maximal productivity of algal-mass. Whereas the rate of mixing exerted little influence on productivity and photosynthetic efficiency in cultures of relatively low algal density, its effect became ever more significant as algal concentration was increased. Maximal mixing-enhanced cell concentrations and productivity of biomass were obtained at the highest light intensity used. At each level of incident light intensity, maximum productivity and photosynthetic efficiency could be achieved only when algal concentration and mixing rates were optimized. The higher the intensity of the light source, the higher became the optimal culture density, highest algal concentrations and productivity of biomass being obtained at the highest light intensity used. The rate of mixing required careful optimization: when too low, maximal productivity resulting from the most efficient utilization of light could not be obtained. Too high a rate of mixing resulted in cell damage and reduced output rate.<\/p>\n<p>Key words   Spirulina platensis  &#8211; mixing rate &#8211; light intensity &#8211; algal density &#8211; photobioreactor &#8211; productivity &#8211; photosynthetic efficiency<\/p>\n<p>Original <a href=\"http:\/\/www.springerlink.com\/content\/p156m5807v465k61\/\">Springer Link source here<\/a><\/p>\n<p><b><span style=\"color:red;\">Nature <a href=\"http:\/\/www.oilgae.com\/ref\/oil\/or\/or.html\">gave us<\/a> oil from algae; perhaps <a href=\"http:\/\/www.oilgae.com\/ref\/story\/story.html\">we should try<\/a> Nature&#8217;s way again<\/span><\/b><\/p>\n<p><b><a href=\"http:\/\/www.oilgae.com\/\">Oilgae &#8211; Oil &amp; Biodiesel from Algae<\/a><\/b><br \/><b><a href=\"http:\/\/www.oilgae.com\/blog\/\">Oilgae Blog<\/a><\/b>; The <b><a href=\"http:\/\/www.oilgae.com\/blog\/dir\/dir.html\">complete list of Oilgae Blog articles<\/a><\/b>.<br \/><b><a href=\"http:\/\/www.oilgae.com\/algae\/oil\/biod\/research\/os\/algos.html\">algOS &#8211; Biodiesel from Algae Open Source<\/a><\/b><\/p>\n<p>About Oilgae &#8211; <b><a href=\"http:\/\/www.oilgae.com\/\">Oilgae &#8211; Oil &amp; Biodiesel from Algae<\/a><\/b> has a focus on biodiesel production from algae while also discussing alternative energy in general.
