“…Although the addition of an external nitrogen source such as NaNO 3 showed a biomass production-promoting effect at low HH concentrations (Figure 4), the low biomass production rates indicate that A. platensis is not capable of adapting under concentrations higher than 10% (v/v). This may be related to the possible inhibitory effect that compounds such as acetic acid and formic acid can generate by increasing their concentration [32,33]. with the difference that higher biomass production rates were obtained in the 5% treatment (1.94 ± 0.06 g/L), while in the treatment with a concentration of 10% (v/v), a production of 0.59 ± 0.02, likewise, no growth was observed in the 15% (v/v) treatment.…”

The proliferation of Sargassum biomass in various coastal areas has led to environmental and socio-economic problems. However, due to their unique composition, these biomasses offer versatile applications, prompting research into their potential in third-generation biorefineries. In this study, the hydrothermal processing of Sargassum sp. was evaluated under specific conditions at 190 °C/50 min and 150 °C/30 min. The resulting hydrolysates (liquid phase) were used as alternative culture media for cultivation. Nine treatments for the cultivation of Arthrospira platensis were assessed, varying the concentration of hydrothermal hydrolysates (HH) at 190 °C/50 min: T1 (5% v/v), T2 (10% v/v), and T3 (15% v/v). T4 (5% v/v), T5 (10% v/v), and T6 (15% v/v), maintaining the same HH conditions, and with the addition of 0.7 g/L NaNO3; and treatments T7, T8, and T9 had concentrations of 5%, 10%, and 15% of HH, respectively, at 150 °C/30 min with the addition of 0.7 g/L NaNO3, respectively. Each treatment was inoculated with 15% (v/v) of A. platensis. Growth kinetics were performed by sampling every three days for 24 days. Quantification of soluble proteins was performed for the best conditions of biomass production. The microalgae demonstrated the ability to grow under mixotrophic medium conditions and to utilize the available carbon sources in the culture medium. Treatment 4 has the highest biomass, with an Xmax (g/L) of 1.94 ± 0.06 and a protein production of 24.17 ± 0.86% (w/w). Therefore, this microalgal biomass can be used in the food matrix according to the biorefinery concept.

“…This phenomenon can occur because in media without dilution and 2x dilution the light used by wild algae to carry out photosynthesis is blocked by media that are too dark. The lack of incoming light intensity results in inhibited growth of wild algae cells in media without dilution and 2x dilution (Jasni et al, 2020).…”

Palm Oil Mill Effluent (POME) is liquid waste produced from palm oil processing. The quantity of POME in Indonesia has increased from year by year. POME is not a toxic material, but it will be very dangerous if it is thrown directly without pre-processing, because it will harm the aquatic ecosystem due to its high content of COD (Chemical Oxygen Demand) and BOD (Biological Oxygen Demand). POME has also a high content of nitrogen (N) and phosphor (P), which make POME can be used as medium for microalgae growth. Therefore, this research is aimed to study pretreatment and to utilize its nutrient content (N, P) for medium of spirulina growth. Pretreatment of POME research was conducted by using two stage of cultivation (Chlamydomonas and Chlorella) and dilution factor (0-4x). The result of this pretreatment was then used for Spirulina growth. Spirulina cultivation was conducted by nutrient addition and without nutrient addition. This research showed that the best performing variation of dilution rate to cultivate Spirulina is 4x dilution. It showed that 4x dilution could reduce COD content until 128.33 mg/L. Besides that, in 4x dilution, microalgae as Chlamydomonas, Chlorella, and Spirulina had the highest growth rate as compared to 2x dilution and without dilution. The best wild algae for pretreatment of POME is Chlorella. Because by using wild algae Chlorella, COD content could be reduced until 128.33 mg/L and achieve the lowest COD content compared with Chlamydomonas. For microalgae growth, addition of nutrient is better than without nutrient, because nutrient could enhance Spirulina photosynthesis.

“…Similarly to other wastewaters, POME may contain inhibitors, such as excessive amounts of residual oil, which can lead to microalgae sedimentation and, consequently, a reduction in treatment efficiency due to biomass losses [85]. For those reasons, pretreatments such as anaerobic digestion of POME may be critical before microalgae cultivation [83], with AD eventually followed by centrifugation for solids [86].…”

Agro-Industrial Wastewaters for Algal Biomass Production, Bio-Based Products, and Biofuels in a Circular Bioeconomy

Recycling bioresources is the only way to sustainably meet a growing world population’s food and energy needs. One of the ways to do so is by using agro-industry wastewater to cultivate microalgae. While the industrial production of microalgae requires large volumes of water, existing agro-industry processes generate large volumes of wastewater with eutrophicating nutrients and organic carbon that must be removed before recycling the water back into the environment. Coupling these two processes can benefit the flourishing microalgal industry, which requires water, and the agro-industry, which could gain extra revenue by converting a waste stream into a bioproduct. Microalgal biomass can be used to produce energy, nutritional biomass, and specialty products. However, there are challenges to establishing stable and circular processes, from microalgae selection and adaptation to pretreating and reclaiming energy from residues. This review discusses the potential of agro-industry residues for microalgal production, with a particular interest in the composition and the use of important primary (raw) and secondary (digestate) effluents generated in large volumes: sugarcane vinasse, palm oil mill effluent, cassava processing waster, abattoir wastewater, dairy processing wastewater, and aquaculture wastewater. It also overviews recent examples of microalgae production in residues and aspects of process integration and possible products, avoiding xenobiotics and heavy metal recycling. As virtually all agro-industries have boilers emitting CO2 that microalgae can use, and many industries could benefit from anaerobic digestion to reclaim energy from the effluents before microalgal cultivation, the use of gaseous effluents is also discussed in the text.
