“…The concentration of DIC in the culture medium can be increased by continuous or intermittent CO 2 aeration, as has been demonstrated in many studies (Matsudo et al, 2012;Chen et al, 2016;Duarte et al, 2017;Qiu et al, 2017;Almomani et al, 2019). Bao et al (2012) indicated that CO 2 absorptivity has a positive correlation with pH value and a negative correlation with total carbon concentration.…”

“…In conclusion, in the present study, the optimal DIC concentration, phosphate concentration, and pH conditions for biomass production were demonstrated for two Spirulina strains, which can be used to produce biomass and fix CO 2 on a large scale. Overall, algal strain selection and process optimization of cultivation conditions may be a key area for future development (Duarte et al, 2017).…”

“…Carbon content in algal cells (X cbm ) was determined using an elemental analyzer (Vario EL III, Germany) (da Silva Vaz et al, 2016). M CO2 and M C were the molecular weights of carbon dioxide and carbon, respectively (Duarte et al, 2017).…”

“…Among the different strategies for mitigating CO 2 , biological CO 2 mitigation through microalgae has recently received considerable attention due to their higher CO 2 fixation capability and bioactive substances contained in their biomass (Wang et al, 2008;Yoo et al, 2010;Matsudo et al, 2012;Hancke et al, 2015;Duarte et al, 2017). Several studies have shown that microalgal growth can be improved by CO 2 from the atmosphere or flue gases and they have better CO 2 fixation abilities (10-50 times greater) than terrestrial plants (Chen et al, 2013;Yadav and Sen, 2017).…”

In order to select excellent strains with high CO 2 fixation capability on a large scale, nine Spirulina species were cultivated in columnar photobioreactors with the addition of 10% CO 2. The two species selected (208 and 220) were optimized for pH value, total dissolved inorganic carbon (DIC), and phosphorus content with intermittent CO 2 addition in 4 m 2 indoor raceway ponds. On the basis of biomass accumulation and CO 2 fixation rate in the present study, the optimum pH, DIC, and phosphate concentration were 9.5, 0.1 mol L −1 , and 200 mg L −1 for both strains, respectively. Lastly, the two strains selected were semi-continuously cultivated successfully for CO 2 mitigation in 605 m 2 raceway ponds aerated with food-grade CO 2 purified from a coal chemical flue gas on a large scale. The daily average biomass dry weight of the two stains reached up to 18.7 and 13.2 g m −2 d −1 , respectively, suggesting the two Spirulina strains can be utilized for mass production.

“…Nesta condição não houve diferença significativa na Pmáx, TBmáx e Emáx (p > 0,05) (Tabela 1). Entretanto, Pmáx e a TBmáx, obtidas com C. fusca LEB 111 com adição periódica de MEA, foi 90% e 4% superior, respectivamente, ao encontrado por Duarte et al (2017) (80 mg L -1 d -1 e 146,7 mg L -1 d -1 ), em cultivos com a mesma cepa, em fotobiorreatores tubulares de 2,0 L e injeção de 10% de CO2 comercial.…”

RESUMO -O objetivo do trabalho foi avaliar o cultivo e biofixação de CO2 por Chlorella fusca LEB 111 com adição periódica de monoetanolamina (MEA). Para isso, foram realizados ensaios em batelada alimentada com CO2 e MEA, em fotobiorreatores tubulares verticais de 1,8 L, a 30 °C, 44,8 µmolfótons m -2 s -1 , fotoperíodo 12 h claro/12 h escuro, por 15 d. Assim, foi constatado que a adição periódica de MEA promoveu maior acúmulo de carbono no meio e não reduziu o crescimento.

The present study was aimed to develop a membrane sparger (MS) integrated into a tubular photobioreactor to promote the increase of the carbon dioxide (CO2) fixation by Spirulina sp. LEB 18 cultures. The use of MS for the CO2 supply in Spirulina cultures resulted not only in the increase of DIC concentrations but also in the highest accumulated DIC concentration in the liquid medium (127.4 mg L−1 d−1). The highest values of biomass concentration (1.98 g L−1), biomass productivity (131.8 mg L−1 d−1), carbon in biomass (47.9% w w−1), CO2 fixation rate (231.6 mg L−1 d−1), and CO2 use efficiency (80.5% w w−1) by Spirulina were verified with MS, compared to the culture with conventional sparger for CO2 supply. Spirulina biomass in both culture conditions had high protein contents varying from 64.9 to 69% (w w−1). MS can be considered an innovative system for the supply of carbon for the microalgae cultivation and biomass production. Moreover, the use of membrane system might contribute to increased process efficiency with a reduced cost of biomass production.
