“…These microorganisms might have beneficial responses to A. cylindrica by exchange of nutrients, excreting growth-promoting compounds, vitamins, and protecting from competitors (Ma et al, 2014;Cho et al, 2015). Paddock et al (2020) suggested that the presence of a complex microbial community in wastewater can enhance wastewater treatment and biomass production.…”

Fruit peels are usually disposed of or treated as fertilizer. The peel, however, contains rich nutrients that can be used as a medium for growing microbes. Conventional culture medium is widely used for growing microbes, but the cost is very high and it is not suitable to produce cyanobacterium-based biofuel, biomass, and in other applications. Therefore, this study explores the potential for using fruit peels as a culture medium for Anabaena cylindrica. The fruit peels were dried, homogenized, and filtered to make different concentrations of fruit peel media (5%, 10% and 20%). For comparison, BG-11 medium acted as a positive control whereas deionized water serves as a negative control in this experiment. Growth of A. cylindrica in different types of media was analyzed after cell counting using a hemacytometer and biomass measuring. The cyanobacterial growth rate and biomass production were recorded in different types of fruit peel media with different concentrations. A. cylindrica have greater biomass yield when growing in 20% papaya peel medium and a higher growth rate when growing in 10% pineapple peel media compared to that growing in the BG-11 medium. In other words, the fruit peel media have more potential in growing cyanobacteria than conventional medium.

“…The use of wastewater as the culture medium for microalgae may reduce the use of commercial fertilizers and at the same time minimize freshwater consumption [95][96][97]. Therefore, the use of microalgae-bacteria consortia in wastewater treatment has been widely studied, revealing that the microbial community plays an important role on the performance of the system [98][99][100]. Because the natural bacterial communities in wastewater effluents are a combination of beneficial and competing species, artificial consortia are preferred to boost microalgal biomass production.…”

“…Because the natural bacterial communities in wastewater effluents are a combination of beneficial and competing species, artificial consortia are preferred to boost microalgal biomass production. For instance, analyses of the microbiome associated with the microalga Chlorella sorokiniana cultivated on anaerobic digestate effluent revealed that the microalgae biomass was correlated negatively with the relative abundance of the genus Pusillimonas [98]. Conversely, a significant improvement on microalgal biomass was observed with an artificial consortium comprised of two Chlorella strains and the bacteria Klebsiella pneumoniae and Acinetobacter calcoaceticus growing in artificial wastewater as well as in raw dairy wastewater [101].…”

Engineered mutualistic consortia of microalgae and bacteria may be a means of assembling a novel combination of metabolic capabilities with potential biotechnological advantages. Microalgae are promising organisms for the sustainable production of metabolites of commercial interest, such as lipids, carbohydrates, pigments, and proteins. Several studies reveal that microalgae growth and cellular storage of these metabolites can be enhanced significantly by co-cultivation with growth-promoting bacteria. This review summarizes the state of the art of microalgae–bacteria consortia for the production of microalgal metabolites. We discuss the current knowledge on microalgae–bacteria mutualism and the mechanisms of bacteria to enhance microalgae metabolism. Furthermore, the potential routes for a microalgae–bacteria biorefinery are outlined in an attempt to overcome the economic failures and negative energy balances of the existing production processes.

“…Hence, considerable efforts have been focused on the mitigation of the negative impacts on the environment of the waste generation, especially on wastewater production, and the worldwide consumption of energy (Chen et al, 2013;Posadas et al, 2017;Alam and Wang, 2019;Maulana et al, 2019). Based on both goals, microalgae cultivation has been evaluated as a potential source of renewable energy (Chiu et al, 2014;Komolafe et al, 2014;Shchegolkova et al, 2018;Alam and Wang, 2019;Nguyen et al, 2019;Zabed et al, 2020) and pollutant removal agent (Caporgno et al, 2015;Novoveská et al, 2016;Gonçalves et al, 2017;Paddock et al, 2020;Shahid et al, 2020;Al-Jabri et al, 2021) in recent years.…”

“…Thus, microalgae in different wastewater streams have been evaluated within wastewater treatment systems because of their efficient removal of nutrients and heavy metals and the generation of biomass through CO2 fixation (Maulana et al, 2019). Researchers (Li et al, 2019;Paddock et al, 2020;Al-Jabri et al, 2021;Hussain et al, 2021) in this area have shown several benefits in its application over traditional wastewater treatment processes such as: ▪ the reduced cost of treating wastewaters because of microalgae biocapability to assimilate pollutants, and uptake nutrients; ▪ the removal of nutrients from the wastewater reduces the effect of eutrophication on water bodies and help to comply with standards regulation for stream discharge; ▪ microalgae biomass could be used as a valuable source for the production of biofuels; ▪ inorganic carbon fixation by the photosynthetic capacity of microalgae can reduce greenhouse gas emissions associated with fossil fuels.…”

Microalgae cultivation integrated into agro-industrial wastewater treatment

The world demands more and more energy due to the continuous population increase. In parallel, high organic and nutrient contents of wastewater streams are generated from anthropogenic activities like urbanization, industrialization, and agricultural practices. The continuous discharge of these wastewater streams into water bodies has been considered responsible for oxygen depletion and eutrophication in the environment. Integrating microalgae cultivation into wastewater treatment can be a promising solution to produce renewable energy while removing pollutants. In contrast to several review articles published about microalgae cultivation on different wastewater streams, the current review is focusing mainly on microalgae-based wastewater treatment on agricultural waste streams. Hence, first of all, the main characteristics of different agricultural streams will be described, then microalgal consortia cultivation, as well as monoculture strains, will be evaluated. Moreover, the photobioreactor systems for agricultural wastewater treatment will also be summarized. Finally, harvesting methods for microalgae recovery will be presented.
