“…Taking in account that approximately 50% of the dry weight of the bacterial cells are proteins, the protein extract that can be recovered from sewage sludge is very promising. Nevertheless, apart from the bacterial cultures, the SCP can also be obtained from other types of biomasses such as microscopic algae, yeast or fungi [ 55 ]. Some examples of SCP production from different streams are shown in Table 5 .…”

“…Regarding legislation for the use of SCP obtained from waste, such as wastewater, the review from Hülsen and colleagues [ 55 ] states that there are several guidelines and regulations around the world with complex and case-dependent situations to commercialize this type of product. The different legislations differ between food for humans and for animals, and in this last category, between pets and livestock.…”

“…There are also differences between food, feed additives, and medical feed. Therefore, the presence of pathogens, xenobiotics, metals, etc., which are present in most of the wastewater streams from municipal WWTPs, causes the production of SCP to be preferentially applied to wastewater streams generated by the food processing industries [ 55 ].…”

Over the last few years, wastewater treatment plants (WWTPs) have been rebranded as water resource recovery facilities (WRRFs), which recognize the resource recovery potential that exists in wastewater streams. WRRFs contribute to a circular economy by not only producing clean water but by recovering valuable resources such as nutrients, energy, and other bio-based materials. To this aim, huge efforts in technological progress have been made to valorize sewage and sewage sludge, transforming them into valuable resources. This review summarizes some of the widely used and effective strategies applied at pilot- and full-scale settings in order to valorize the wastewater treatment process. An overview of the different technologies applied in the water and sludge line is presented, covering a broad range of resources, i.e., water, biomass, energy, nutrients, volatile fatty acids (VFA), polyhydroxyalkanoates (PHA), and exopolymeric substances (EPS). Moreover, guidelines and regulations around the world related to water reuse and resource valorization are reviewed.

“…Production of SCP from processing wastewater improves the wastewater quality by neutralizing materials that are harmful to the environment (Giavasis and Petrotos, 2016;Spalvins et al, 2018a;Saejung and Salasook, 2020), also save the huge amounts required for their disposal (Kosseva, 2009). Substrates in liquid wastes are readily digestible and can easily be converted into biomass (Hülsen et al, 2019).…”

The roles of protein in bodybuilding and the regulation of biological processes are important in sustaining life. A large amount of protein is required by both humans and animals and this cannot be supplied by only conventional sources. This is because of the rapid increase in world population. The present sources of protein will not meet global protein demand in years to come. Scientists explore the production of single-cell protein (SCP), as an alternative source of protein, through the utilization of wastes and low-value materials. SCP can supply high-quality protein containing both essential and non-essential amino acids that can be utilized by humans and animals. Protein from microbial biomass is cheaper than animal proteins because the substrates used in the production are generally cheaper and more readily available. Moreover, the production process does not require arable land and the entire process can be completed within a short time. This article reviewed the process of SCP production. Different raw materials used in the production and variations in growth media preparation methods were discussed. Various sources of fermentation microorganisms and their potential substrate were reviewed. Growth media enrichment using different carbon, nitrogen, and mineral sources was also discussed.

“…A number of single cell ingredients of diverse (bacterial, fungal, algal) origin are also considered to hold much promise as sustainable feed resources for fish and shrimp (Glencross et al, 2020). Microbial or single cell proteins (SCP) can meet the increasing demands for sustainable sources of protein, as they offer greater flexibility with the products and production approaches (Anupama and Ravindra, 2000; Øverland et al, 2010; Matassa et al, 2016; Hulsen et al, 2019; Agboola et al, 2020; Glencross et al, 2020). For instance, bacterial biomass based microbial protein can be produced from agriculture waste (Adeoye et al, 2021); wood‐based biorefinery residue (Smárason et al, 2019; Solberg et al, 2021); waste from ethanol industry, natural and biogas (Ritala et al, 2017); carbon dioxide or flue gases (Sillman et al, 2019); and even from aquaculture waste (Schneider et al, 2006).…”

Progressive growth of aquaculture to meet the increasing demand for seafood is largely dependent on the reliable supply of quality aquafeed ingredients, which are sustainable ecologically, commercially and socially (Kim et al., 2019;Tacon, 2020). Historically, fish meal (FM) has been considered as the ideal protein source for most of the intensively farmed fish. But, given challenges such as stagnating production, price volatility, environmental impact of reduction fisheries, growing scrutiny on the conversion of food grade fish to fish meal
