“…Integrated systems using the CO 2 -enriched gas exit of aerobic cultures to aerate autotrophic microalgae cultures were successfully tested recently [16][17][18], and CO 2 from bioethanol produced from sugarcane fermentation was used for the continuous cultivation of Arthrospira platensis [19][20][21].…”

a b s t r a c tIn this study, we evaluated the effect of growing Dunaliella tertiolecta microalgae using CO 2 from brewing on the production of lipid and carotenoid-rich biomass. An integrated system of microalgae photobioreactors and yeast fermenters was used, thus providing biological CO 2 continuously to the microalgae culture. Yeast cultures were first carried out in fermenters using synthetic medium. With a step-wise increasing glucose concentration from 10 to 60 g L −1 , the CO 2 that came from 24 h yeast cultivation gave the highest biomass formation, carotenoids and lipid contents, and productivities by the microalgae. Reproduction of these experiments using beer fermentation instead of synthetic medium was carried out using different volumes of wort coupled to microalgae cultivations. The values obtained for microalgae cultures when using CO 2 from beer fermentation were 1.10 ± 0.05 g L −1 of biomass, 0.18 ± 0.01 g L −1 day −1 of biomass productivity, 0.58 ± 0.06 day −1 specific growth rate, 4.74 ± 0.59 mg g −1 of carotenoids per biomass dry weight, 0.86 ± 0.06 mg L −1 day −1 of carotenoids productivity, and 135 ± 4 mg g −1 of lipids. These values are almost twice as high as the values observed for control cultivations in which atmospheric CO 2 was used, showing that the integration system of yeast fermenters and microalgae photobioreactors is an interesting alternative to improve biomass formation and product contents. All D. tertiolecta cultures showed the same carotenoids profile, being lutein the major carotenoid (46.7 ± 2.0% of total carotenoids).

“…Microalgae have a chemical composition containing 70–230 g kg −1 lipids, 50–230 g kg −1 carbohydrates and 60–520 g kg −1 proteins on a dry matter basis (DMB), which can vary depending on the genus and species, and on the growing conditions for a particular species. Several factors, including nutrient availability, temperature, pH and light intensity, can affect microalgal chemical composition …”

Potential application of microalga Spirulina platensis as a protein source

et al. 2016

The high protein level of various microalgal species is one of the main reasons to consider them an unconventional source of this compound. Spirulina platensis stands out for being one of the richest protein sources of microbial origin (460-630 g kg , dry matter basis), having similar protein levels when compared to meat and soybeans. The use of S. platensis in food can bring benefits to human health owing to its chemical composition, since it has high levels of vitamins, minerals, phenolics, essential fatty acids, amino acids and pigments. Furthermore, the development of new protein sources to supply the shortage of this nutrient is an urgent need, and protein from S. platensis plays an important role in this scenario. In this sense, extraction processes that allow maximum protein yield and total utilization of biomass is an urgent need, and ultrasonic waves have proven to be an effective extraction technique. The number of scientific papers related to protein fraction from S. platensis is still limited; thus further studies on its functional and technological properties are needed. © 2016 Society of Chemical Industry.

“…bicarbonate is used, it represents 60% of the cost of nutrients (Alava et al, 1997), which is one of the reasons for studying the effects of lowering the concentration of the carbon source and finding alternative sources of this nutrient, such as molasses , residual CO 2 (Ferreira et al, 2012) and synthetic CO 2 (Rosa et al, 2011).…”

-The carbon source is the most expensive nutrient for Spirulina production; effluents from anaerobic digestion contain this nutrient in the form of HCO 3 -. The aim of this study was to assess the growth kinetics, composition and fatty acid profile of Spirulina sp. LEB-18 grown in standard Zarrouk medium (NaHCO 3 16.8 g L -1) and in Zarrouk medium replaced with 20% (v/v) effluent with reduced concentrations of NaHCO 3 (5.3 and 2.8 g L -1 ). The use of effluent and lower concentrations of HCO 3 -was found to be an alternative to reduce the costs of Spirulina production, because there were no significant differences in growth parameters (μ max 0.324 -0.354 d -1 ; P max 0.280 -0.297 g L -1 d -1 ), in the different culture medium used. Lipids ranged between 4.9 and 5.0%; the media with effluent had higher levels of linoleic acid compared to the standard medium.
