“…It is of interest due its tolerance to high CO 2 concentrations and the fact that it can grow to high cell density [29]. Just like all other microalgae, it can produce value added by-products that can enable their processes more economical.…”

Blue green algae also called cyanobacteria are considered to be the photosynthetic prokaryotes. Their similarities with both higher plants and simple bacteria have made them ideal model systems for intensive research in varied spheres of biology. Their role in nitrogen fixation is well known but their role as prebiotics to support the growth of probiotic bacteria is an upcoming field of study. Prebiotics includes indigestible carbohydrates mainly oligosaccharides that benefit the host organism by selectively stimulating the growth or activity of one or a limited number of probiotic bacteria in the colon. Spirulina, a cyanobacterium is a photoautotrophic microorganism, widely distributed in nature and is consumed as human food supplement for centuries because of its best known nutritional value. It contains 78% proteins, vitamins, 4-7% lipids, minerals, carbohydrates and some natural pigments. Due to the presence of these phytonutrients, it has corrective properties against several diseases like cancer, hypertension, hypercholesterolemia, diabetes, anaemia etc. Research studies have reported that the extracellular products produced by Spirulina platensis significantly promotes the growth of lactic acid bacteria such as Lactococcus lactis, Streptococcus thermophilus, Lactobacillus casei, Lactobacillus acidophilus, and Lactobacillus bulgaricus. The present paper would focus on the prebiotic efficiency of certain blue green algae on probiotic microorganisms.

“…The flat plate photobioreactors can receive greater sunlight for microalgae growth although there is potential for cell mixing. The microalgae cell density could reach up to 80g/L dry cell weight, significantly higher than the cell density of a pond system, which ranges within several g/L (Hu, 1998). Another design for the photoreactor is the tubular photoreactor, made with a diameter less than 0.1 m to maximize the sunlight harvest by microalgae.…”

“…Collecting empirical data on these parameters is necessary for modeling, defining optimum conditions, and understanding production under various growth conditions. The design and operational factors that influence these parameters include depth of culture, mixing rate (cell light/dark cycling frequency), dilution rate, nutrients, temperature, salinity, and distance of light source from the culture surface in the case of artificially lighted systems 10,27,29,30,[38][39][40][41][42] . Numerical models, such as those developed by Benson et al 7,37,43 and Lohrey and Kochergin 16 are needed to simulate and optimize microalgal production in sugar-mill wastewaters.…”

Sugar-mill wastewaters have potential to support microalgal biomass production for use as a biofuel feedstock (lipid source). Growth kinetics, light dynamics, and lipid production in multispecies-microalgae cultures collected from a sugar-mill pond are reported in this paper. Lipid content of the microalgae collected from the pond water was 14.5 % (w/w). Culturing the same microalgae in a photobioreactor on the pond wastewater supplemented with Gillard's F/2 and CO 2 , and irradiated with 151 to 337 μmol s -1 m -2 artificial light produced cells with lipid contents of 11 % (w/w) at 25 °C, 35 % (w/w) at 31 °C, and 28.6 % (w/w) at 33 °C. The maximum specific growth rates (µ max ) at 25 °C, 31 °C, and 33 °C were 0.64 d -1 , 2.5 d, and 2.7 d -1 , respectively. Under these conditions, cell densities as high as 1020 g cell dry mass (CDM) m -3 were recorded. Total scalar irradiance attenuation coefficient (k 0 ) was 0.275 m -1 in clear water and 30.5 m -1 in the dense culture. The attenuation coefficient of irradiance due to biomass (k B ) was found to be a linear function of cell concentration in this work.
