Growing Chlorella vulgaris into bioreactors set in solar greenhouse, towards biofuel: Nutrient composition

چکیده
Large scale microalgae cultivation actually represents a potential new source of renewable energy in the form of biofuel. Microalgae are individual plant cells which have the ability to photosynthesize and therefore utilize CO2, micronutrients and solar light to multiply and produce carbohydrates, lipids and proteins. Microalgae cultivation has several advantages over land grown crops. The major advantages are 1) a much faster growth rate, 2) the fact that their cultivation does not need the application of insecticides and pesticides and 3) the potential for cultivation in large scale in either open ponds or closed photo‒ bioreactors. As microalgae cultivation removes atmospheric carbon dioxide their cultivation can be potentially scaled up in such a way as to absorb CO2 emissions from fossil fuel burning factories. Additionally, the spent algal mass, after the oil extraction, can be used either as an animal feed, since it contains substantial quantities of proteins, carbohydrates, some remaining oil and various micronutrients, or as an agricultural soil additive-nutrient enhancer. In recent years, several studies have been carried out both on a fundamental and on an applications oriented basis concerning the synergistic cultivation of microalgae for biofuel production with biological CO2sequestration. 1‒5

The unicellular green alga, Chlorella vulgaris UTEX 395, represents a promising biocatalyst for renewable biofuel production due to its relatively rapid growth rate and high lipid accumulation capacity (Guarnieri et al., 2011, 2012; Gerken et al., 2013; Griffiths et al., 2014; Zuniga et al., 2016). Prior analyses have unveiled the global proteome dynamics of C. vulgaris following nitrogen deple...
متن کاملImpact of various media and organic carbon sources on biofuel production potential from Chlorella spp.
In this study, five Chlorella species (Chlorella vulgaris, Chlorella minutissima, Chlorella pyrenoidosa, Chlorella sp.1 and Chlorella sp.2) were grown in various nutrient medium including BG-11, BBM, Fog's medium and M4N medium for the evolution of biomass and lipid production potential. Among the tested medium, BG-11 was found most economical and efficient medium for all Chlorella species. To ...
متن کاملComparing Nutrient Removal from Membrane Filtered and Unfiltered Domestic Wastewater Using Chlorella vulgaris
The nutrient removal efficiency of Chlorella vulgaris cultivated in domestic wastewater was investigated, along with the potential to use membrane filtration as a pre-treatment tool during the wastewater treatment process. Chlorella vulgaris was batch cultivated for 12 days in a bubble column system with two different wastewater treatments. Maximum uptake of 94.18% ammonium (NH₄-N) and 97.69% o...
