The control of temperature and light intensity in microalgae culture in outdoor tanks is difficult. Progress in algal biotechnology and the use of photo-bioreactors, metabolic engineering and other advances supported development of a novel underwater light bank reactor that allows for more effective light utilization by cultured microalgae.
