Abstract

:

The lipid, fatty acid, protein, and carbohydrate contents in cyanobacterial strains and biomass can vary by orders of magnitude. Many publications (thousands of peer-reviewed articles) require more work to extract their precise concentration values (i.e., different units, inaccurate data), which makes them not easily exploitable. For this purpose, tables have been compiled from the literature data, including lipids, fatty acids, proteins, and carbohydrates composition and quantities in cyanobacteria. A lot of data (323) were collected after careful a literature search, according to selected criteria in order to distinguish separately cyanobacteria, and according to categories of genus and species and generate average values of the contents of these cell components. These data are exploited in a first systematic analysis of the content in types of strains. Our database can be a powerful tool for biologists, chemists, and environmental agencies to determine the potential concentration of high-value chemical building blocks directly from low-value bloom biomass, cell cultures, or debris in the sediment, offering the potential to minimize environmental waste and add value to the agro-industrial residues. The database can also support strategies for food manufacturers to develop new products with optimized properties for veterinarian applications.

1. Introduction

Cyanobacteria can form blooms (excessive proliferation) according to changes in the natural environmental conditions (i.e., temperature, light, and nutrients) [1,2]. The leading causes of this increase are the environmental impacts caused by anthropic actions that promote the eutrophication of aquatic ecosystems, combined with climate change, increased water temperature, and the increased atmospheric levels of carbon dioxide [1,3]. As a result, the frequency, distribution, intensity, and duration of these blooms have been increasing worldwide. Among the organisms present in the blooms, cyanobacteria stand out, as they can produce toxic substances, which in large quantities can affect aquatic fauna, causing imbalances in the ecosystem [4,5,6].

On the other hand, non-toxic cyanobacterial species have great potential for biotechnological application. They can be used in several industrial sectors, for example, in the food, energy, and pharmaceutical industries, among others, adding value to a raw material that is still little explored [7,8,9]. The study of different strains of cyanobacteria is important due to the different characteristics that these microorganisms present, in addition to their capacity of producing different primary and secondary metabolites. For example, according to Rodolfi et al. [10], some species can fix carbon dioxide (CO₂) directly and produce cell biomass suitable for an economically viable dense culture of cyanobacteria [11]. Depending on the conditions, strains of Microcystis aeruginosa (i.e., CCIBt 3106, LTPNA 03, LTPNA 01, and LTPNA 05) can produce or not microcystins [12,13,14], and this suggests that without the extra energy cost of synthesizing cyanotoxin, these non-toxic strains could invest in nutrient reserves [13].

The main primary metabolites produced by cyanobacteria are lipids, carbohydrates, and proteins [15]. Lipids are essential chemical compounds in cyanobacteria, which can be used as a source of food, animal feed, and biodiesel [14,16,17]. According to Sinensky [18], the ability to modify the type and amount of cell lipids is one of the reasons that can explain the fact that cyanobacteria manage to survive under diverse and extreme conditions (e.g., extremophile species in Antarctica and hot springs).

The production of carbohydrates In cyanobacteria for industrial applications is a promising area for biotechnology [19]. For example, sucrose and glycogen from cyanobacteria can be considered good sources for the production of biofuels [20,21]. Since these microorganisms are also interesting producers of proteins, they can be used in food as valuable ingredients [22]. For example, cyanobacteria rich in proteins can be used in the food industry as a protein extract, which may have emulsifying or gelling properties [22]. Several studies have analyzed protein concentration in cyanobacteria [13,23,24,25].

Due to the satisfactory concentrations of nutrients in cyanobacteria, studies on the characterization of fatty acids, lipids, carbohydrates, and proteins are abundant. The large number of studies related to cyanobacteria in the molecular, environmental, and biotechnological areas, among others, makes it difficult to search for specific information on the amount of these macronutrients. Thus, the objective was to collect data on these biocompounds to create a database that compiles the important data for different researches.

2. Materials and Methods

Data selection depends on the purpose of the study and data availability [26]. From this premise, data were selected from published research articles using the Google Scholar, Scielo, PubMed, Science Direct, and Web of Science databases. The main inclusion criteria were the impact factor of journals and the publication of articles in the period from 2000 to 2023. The keywords cyanobacteria, lipids, lipid content, fatty acids, carbohydrates, proteins, and biofuel were used for the search (Figure 1). Review articles with consistent and clear data were considered; however, the concentration values were extracted from the original articles.

Independent researchers extracted the necessary information from eligible articles, such as the cyanobacteria genus and species, investigated compounds’ content, collection place, authors, year of publication, and digital object identifier (DOI). The details of the articles included were typed into an Excel spreadsheet (Office 2013, Microsoft, Redmond, WA, USA), contemplating the information mentioned in columns. The studies displayed on the different search platforms, according to the search criteria, were extracted in the “ris” format.

We also researched and compiled the data found in the Platform of National Center for Biotechnology Information (NCBI) of the species and/or genera selected for this review. These data are presented in the Supplementary Material (Table S1).

3. Results

Relevant studies on the concentration of fatty acids, lipids, carbohydrates, and proteins in cyanobacteria were selected, totaling 111 data on fatty acids, 119 on lipids, 60 on carbohydrates, and 33 on proteins (Figure 2). A total of 323 data were analyzed and presented in seven tables, gathering data on fatty acids (Table 1, Table 2, Table 3 and Table 4), lipids (Table 5), carbohydrates (Table 6), and proteins (Table 7). We included articles with consistent or clear data and review articles. The fatty acid structures are presented in the Supplementary Material. Saturated fatty acids have simple structures with only single C–C bonds with a terminal carboxylic group (Table S2), while unsaturated fatty acids have more complex structures containing at least one or more C=C double bonds in the carbon backbone (Tables S3 and S4).

4. Discussion

Cyanobacteria are rich in primary metabolites and have biotechnological potential for energy production and the pharmaceutical and food industries [14,25,93,94]. There are many works in the literature about cyanometabolites. However, some articles need to present the data clearly and concisely. This work proposes setting up a review of the data published in scientific journals making use of important scientific platforms to facilitate finding this information.

Many studies have analyzed how environmental conditions (e.g., temperature, pH, and nitrogen and phosphate levels) can increase the biochemical composition of microalgae and cyanobacteria, mainly fatty acids and lipids [48]. These compounds are essential for cyanobacteria. In cells, lipids are found mainly in the cell membranes, featuring mainly polyunsaturated fatty acids (FAs) in their structure. The unsaturated FAs play an essential role in membrane physiology, and the proportion of unsaturated and saturated FA determines membrane fluidity [95]. Several authors have been quantifying the concentration of fatty acids and lipids in cyanobacteria worldwide [17,27,28,30,36,47,48,96].

Cyanobacteria exhibit high lipid production, as observed in the data collected in Table 5 (119 strains of cyanobacteria). These microorganisms, which can adapt themselves to culture conditions and exhibit high cell growth, are considered ideal lipid sources for pharmaceutical and biofuel production [97]. For example, they produce a wide variety of lipids with antibiotic and antibiofilm activity [98]. Using these compounds in clinical treatments alone or in association with antibiotics can be considered an alternative to current treatments for human diseases. Examples of commercially important lipids produced by cyanobacteria are polyhydroxyalkanoates (PHAs) and polyhydroxybutyrates (PHBs), which are considered a good alternative to synthetic plastics due to their natural origin, optical purity, thermoplasticity, and biodegradability [99].

Cyanobacteria are among the third-generation raw materials that are viable and increasingly studied for use in biodiesel production [100,101]. Large-scale biodiesel production directly depends on the availability of interesting fatty acids in the raw material. Lipids and fatty acids’ total content may depend on the species and strain studied (Table 1, Table 2, Table 3, Table 4 and Table 5), and their content may be altered or induced by different abiotic factors (e.g., pH, mode of operation, photobioreactor configuration, light, and temperature) [102,103].

Some species of cyanobacteria, such as Oscillatoria sp. FW01, can optimize their yield when cultivated under specific conditions. According to the study by Yadav et al. [17], the cultivation of this strain under controlled light and temperature showed a 12% increase in the production of lipids, as well as a 57% increase in that of fatty acids. Thus, the authors considered Oscillatoria sp. FW01 as a raw material to be potentially used for the sustainable production of biodiesel [17].

According to the data gathered in Table 2, it is possible to observe quite a high content of palmitic acid (C16:0) (approximately 36.5%) in the reviewed cyanobacterial species. One of the characteristics of this acid is its small saturated carbon chain with its low oxidation and melting point [104]. These characteristics make this type of acid especially suitable for biodiesel production. The demand for lipids from microorganisms as possible substitutes for fossil fuels has stimulated research into synthetic biofuels. Oliveira et al. [35] investigated the lipid profile of three strains of Amazonian cyanobacteria (Cyanobium sp., Limnothrix sp., and Nostoc sp.), among which Limnotrix sp. showed the best lipid profile and highest amount of C16:0, which are favorable properties for biodiesel production. In addition, it also showed good values of biodiesel quality parameters, i.e., a high oxidative stability (34.9 h) and a cetane number (58.06) above the minimum established by the American Society for Tests and Materials (ASTM).

In the work by Santana-Sánchez et al. [105], the Synechococcus strains were the only ones that exhibited fatty acid profiles mainly composed of C14:0, C16:0, and C16:1 and without polyunsaturated fatty acids. Boutarfa et al. [27] also analyzed the fatty acid profile of the strains of Mastigocladus laminosus (an extremophile found in hot springs), which revealed C16:0 as the main fatty acid (51–53%) and a medium length chain (from C14 to C20). Nostoc sp. MCC41 presents high concentrations of palmitic acid, can grow under mixotrophic conditions, and fixes atmospheric nitrogen [36]. Thanks to these properties, they may represent excellent raw materials for the production of biodiesel.

Carbohydrates are among the leading products of photosynthesis, and in some species of cyanobacteria, their content can reach up to 50% of the dry weight [106]. These compounds are present in the cell wall (structural support) in addition to being stored as an energy source for the cell [97]. A possible biotechnological application of carbohydrates from cyanobacteria is in the area of biofuels, due to the high content of fermentable sugars and low hemicellulose and lignin contents [15,107]. In particular, the feasibility of producing bioethanol from the cyanobacterial biomass depends on the content and composition of the carbohydrates in the cell, both varying and depending on factors such as cultivation conditions and species type. Therefore, the production of carbohydrates by cyanobacteria has become the focus of much research [15,72,73,108] due to their potential application as a substrate for biofuels [109].

Some cultivation conditions favor the accumulation of carbohydrates in cyanobacterial cells, including the limitation of nitrogen in the medium where it is cultivated [72]. In Table 6, where the data referring to the accumulation of total carbohydrates can be found, we can observe a large variability according to the species, i.e., from 15% in Synechococcus sp. [69] up to 70% in Spirulina maxima [70]. However, the best carbohydrate-accumulating species were also grown in nitrogen-poor media (e.g., wastewater-borne cyanobacteria, Arthrospira platensis NIES-39, and Spirulina platensis) [15,21,70]. In other words, some species are able to accumulate carbohydrates more than others, but this capacity can be influenced by the medium in which they are grown.

Another critical question is the demand for food, which is a worrying factor in the world because of the growing population. According to the United Nations, the world population could reach 8.5 billion in 2030 and increase even more to 9.7 billion in 2050, creating a significant challenge related to food production. In this way, the food sector looks for foods or inputs that can add nutritional value and benefit human and animal health. These products are called functional foods, which provide metabolic and nutritional effects on health and essential physiological functions [80,83,107,109].

The search for a healthy diet and lifestyle causes consumers to purchase products that complement their physiological and metabolic needs. As a result, there has been an increase in this food sector, which focuses on consuming carbohydrates, lipids, and proteins. However, food alternatives have been sought as a source of protein, replacing animal sources [80,83,107,110]. Algae and microalgae have emerged as promising alternative sources of macronutrients. However, one of the problems encountered is the high cost of producing biomass, limiting the applications of its use. Due to this problem, research is being carried out on cyanobacteria, mainly due to the ease of their proliferation, generating much biomass.

As the results collected in Table 7 show, cyanobacteria are an excellent source of proteins, either as a food supplement or as an input to increase the concentration of this nutrient in food. Among these microorganisms, Spirulina sp. have stood out due to their excellent properties. They can be applied as biostimulants or biofertilizers, animal feed, or to produce human foods enriched in Spirulina sp., which are already commercially available. In addition, they are used in cosmetics, medicines, and functional foods. These applications, mainly as a source of protein, are possible because they are safe, nutritious, and sustainable raw materials.

For this reason, there is much research into the literature on cyanobacteria, as seen in the above tables. Data related to Spirulina sp. can be compared with those of other species and strains of cyanobacteria, demonstrating that it is still an area to be explored [111]. In addition to those presented, cyanobacteria produce other metabolites that can improve and contribute to a healthy diet, adding value to different products or these raw materials [107,110]. However, as seen in this review article, there are still few reports on the concentrations of proteins in different species and strains of cyanobacteria.

Since proteins have different functions in microorganisms, cyanobacteria show a significant variation in their total content (2.5–66.7%), with an average concentration of 36.9% (Table 7). However, there are still few reports on protein concentration in cyanobacterial biomass. This small overview on protein content demonstrates that this is an area of research still to be explored, mainly by the food industry [77,80,83].

5. Conclusions

The biochemical diversity presented by cyanobacteria has favored the study of these microorganisms in several areas of science. This review is essential to facilitate the consultation and location of data from scientific articles on the composition of cyanobacterial species and strains, including the contents of fatty acids (111), lipids (119), carbohydrates (60), and proteins (33). It was also possible to discuss how these characteristics can be commercially relevant since cyanobacteria have been considered good candidates for several applications; for example, as a source of food supplements for humans and animals and in the production of biofuels.
