“…F v /F m ( Figure 2B ) and Y (II) ( Figure 2C ) had similar trends to ETR, which were all positively correlated with microalgal growth curves ( Cheng et al, 2019 ; Xu et al, 2021 ). Hence, the photosynthetic fluorescence parameters ETR, F v /F m , and Y (II) can be used to quickly evaluate the final relative value of microalgal concentration in wastewater ( Wang et al, 2022 ). Rapid evaluation of the relative values of microalgal concentration under different experimental conditions is very important for selecting the best culture conditions and for subsequent large-scale applications ( Uysal and Ekinci, 2021 ).…”

“…Exploring the cultivation of Chlorella sp. in BWW, Wang et al (2022) obtained not only the maximum biomass concentration of 2.03 g L −1 but also the maximum lipid, carbohydrate, and protein contents of 36.19%, 36.51%, and 19.77%, respectively, with the maximum removal of NH 4 + -N, COD, TN, and TP reaching 94.38%, 88.52%, 96.71%, and 98.68%, respectively. Previous studies have reported the production of methane ( Chen et al, 2016 ) and hydrogen ( Shi et al, 2010 ) by anaerobic fermentation of BWW, but the production of biogas by anaerobic fermentation of BWW–BWG mixtures has not been studied.…”

Digestates from different anaerobic digesters are promising substrates for microalgal culture, leading to effective wastewater treatment and the production of microalgal biomass. However, further detailed research is needed before they can be used on a large scale. The aims of this study were to investigate the culture of Chlorella sp. in DigestateM from anaerobic fermentation of brewer’s grains and brewery wastewater (BWW) and to explore the potential use of the biomass produced under different experimental conditions, including diverse cultivation modes and dilution ratios. Cultivation in DigestateM initiated from 10% (v/v) loading, with 20% BWW, obtained maximum biomass production, reaching 1.36 g L−1 that was 0.27g L−1 higher than 1.09 g L−1 of BG11. In terms of DigestateM remediation, the maximum removal of ammonia nitrogen (NH4+-N), chemical oxygen demand, total nitrogen, and total phosphorus reached 98.20%, 89.98%, 86.98%, and 71.86%, respectively. The maximum lipid, carbohydrate, and protein contents were 41.60%, 32.44%, and 27.72%, respectively. The growth of Chlorella sp. may be inhibited when the Y(II)–Fv/Fm ratio is less than 0.4.

This paper aims to assess the potential of basidiomycete fungi to mycoremediate brewery wastewater and generate a bioactive molecule (β-glucan) for industrial applications. MethodsSix basidiomycete fungi, Ganoderma applanatum, Ganoderma lipsiense, Pleurotus ostreatus, Pycnoporus sanguineus, Lentinula edodes, and Oudemansiela canarii were grown in submerged fermentation using brewery wastewater (BW). β-glucan production, biomass concentration, reducing sugar content, and pH were evaluated and the fungus with the highest β-glucan production was subjected to a kinetic study of β-glucan production. ResultsResults showed that BW has important nutrients for fungi growth and all species had high biomass production. The highest production of β-glucans was for G. lipsiense (23.87%) and its kinetic study showed the highest production of β-glucans at 14 days and the greatest increase in biomass at 21 days. There was a correlation between the production of β-glucans and the consumption of BW substrate and a decrease in chemical oxygen demand (81% at 21 days), nitrate (<3.00 mg L -1 ), total phosphorus (66.326 mg L -1 ), and total dissolved solids (634.1 mg L -1 ). ConclusionThis study highlighted a sustainable use of BW for its remediation besides fungal biomass production as a source of a high-value product for the biotechnology industry, opening prospects in the circular bioeconomy.

“…Organic wastes are carbon-rich and microalgae have grown on them successfully, previously [148,149]. To remove carbon, nitrogen and phosphorus from waste waters, different algae have been used and their growth assessed on agricultural, brewery, and industrial effluents, with promising results in terms of growth and nutrient removal [150][151][152][153]. Scenedesmus obliquus removed ammonia and nitrogen from municipal wastewater effectively previously [150].…”

Microalgae are a rich resource of lipids, proteins, carbohydrates and pigments with nutritional and health benefits. They increasingly find use as ingredients in functional foods and feeds as well as in cosmetics and agricultural products including biostimulants. One of their distinct advantages is their ability to grow on wastewaters and other waste streams, and they are considered an environmentally friendly and cheap method to recover nutrients and remove pollutants from the environment. However, there are limits concerning their applications if grown on certain waste streams. Within, we collate an overview of existing algal applications and current market scenarios for microalgal products as foods and feeds along with relevant legislative requirements concerning their use in Europe and the United States. Microalgal compounds of interest and their extraction and processing methodologies are summarized, and the benefits and caveats of microalgae cultivated in various waste streams and their applications are discussed.
