“…Saturated fatty acids (SAFAs) and monounsaturated fatty acids (MUFAs) each occurred in significantly lower abundance, constituting 31.3±2.3% and 15.2±5.7%, respectively ( S3 Table ). In terms of distribution and relative abundance, the FAME content of our Dolichospermum strains is thus in good agreement with those previously reported for freshwater representatives of this genus [ 23 , 33 , 69 ] and isolates obtained from the Baltic Sea [ 67 , 70 ]. All Dolichospermum strains exclusively contained higher relative proportions of 14:0, which occurred in trace amount only in the Aphanizomenon and Nodularia strains (<1%) with the exception of Nodularia HEM, where it constituted 2.7% ( S3 Table ).…”

Lipid biomarker signatures as tracers for harmful cyanobacterial blooms in the Baltic Sea

The recent proliferation of harmful cyanobacterial blooms (cyanoHABs) in the Baltic and other marginal seas poses a severe threat for the health of infested ecosystems as e.g. the massive export and decay of cyanobacterial biomass facilitates the spread of bottom water hypoxia. There is evidence that cyanoHABs occurred repeatedly in the Baltic Sea but knowledge of their spatiotemporal distribution and the cyanobacteria that contributed to them is limited. In this study, we examined representatives of the major bloom-forming heterocystous cyanobacteria (i.e. Aphanizomenon, Dolichospermum (formerly Anabaena) and Nodularia) to establish lipid fingerprints that allow tracking these environmentally important diazotrophs in the modern and past Baltic Sea. The distribution of normal and mid-chain branched alkanes, fatty acid methyl esters, bacteriohopanepolyols and heterocyst glycolipids permitted a clear chemotaxonomic separation of the different heterocystous cyanobacteria but also indicated a close phylogenetic relationship between representatives of the genera Aphanizomenon and Dolichospermum. Compared to the discontinuous nature of phytoplankton surveys studies, the distinct lipid profiles reported here will allow obtaining detailed spatiotemporal information on the frequency and intensity of Baltic Sea cyanoHABs as well as their community composition using the time-integrated biomarker signatures recorded in surface and subsurface sediments. As heterocystous cyanobacteria of the genera Aphanizomenon, Dolichospermum and Nodularia are generally known to form massive blooms in many brackish as well as lacustrine systems worldwide, the chemotaxonomic markers introduced in this study may allow investigating cyanoHABs in a great variety of contemporary environments from polar to tropical latitudes.

“…According to their study, three Baltic cyanobacteria strains (Aphanizomenon flos-aquae, Dolichospermum lemmermannii and Nodularia spumigena) in full nutrient levels, as well as phosphorus and nitrogen depleted medium was inoculated and being monitored for 14 days. It was observed a strong negative relationship between lipid content, growth and nutrient availability, resulting in high lipid and pigment production in combination with a limited growth rate in nutrient depleted treatments (Steinhoff et al, 2014). A study carried out on different microalgae found in Mauritian marine water reported that highest amount of lipid was recorded in the Symbiodinium clade C. The presence of biodiesel was detected also by alkaline trans-esterification reaction (Keshini Beetul et al, 2014).…”

“…Since landbased biofuel production competes with conventional food production, a water-based biomass and biofuel production from cyanobacteria offers large potential (Steinhoff et al, 2014). The use of lipids obtained from microalgae biomass has been described as a promising alternative for production of biodiesel to replace petro-diesel (Santos et al, 2014).…”

The experimental design and techniques for biofuel production from different feedstock varies depending on geographical region, water sources (fresh water, sea water, waste water or brackish water) and overall, available species variations. Also the sampling, culture conditions, isolation, purification of cultures, harvesting, fatty acid extraction followed by conversion of extracted lipids to biofuel followed different methods in different studies. Therefore, it is a demand to simplify the techniques, improve the methods, and develop the efficiencies with less laborious inputs but rapid and best outcomes. Biofuel production research should focus not only selecting suitable biomass or obtaining high yield of lipids but also look for economically feasible method along with sufficient and continuous supply of biomass. Considering these, cyanobacteria and microalgae creates a great potential for biofuel production. In this review, we focused on compiling different materials and methods used for different studies and their best outputs towards biofuel production from cyanobacteria and micro-algae.

“…From the biological activity point of view, fatty acids were reported to be anticarcinogenic, antibiotic, antifungal, and antiviral (Burja et al, 2001; El-Baz et al, 2013; Table 1). Among a wide variety of fatty acids, polyunsaturated fatty acids (PUFAs) are of great concern due to their health benefits and an increasing demand in the global market (Steinhoff et al, 2014). The presence of two or more double bonds (methylene-interrupted) in fatty acids (PUFAs) makes them more valuable from nutraceutical point of view.…”

Cyanobacteria and algae having complex photosynthetic systems can channelize absorbed solar energy into other forms of energy for production of food and metabolites. In addition, they are promising biocatalysts and can be used in the field of “white biotechnology” for enhancing the sustainable production of food, metabolites, and green energy sources such as biodiesel. In this review, an endeavor has been made to uncover the significance of various metabolites like phenolics, phytoene/terpenoids, phytols, sterols, free fatty acids, photoprotective compounds (MAAs, scytonemin, carotenoids, polysaccharides, halogenated compounds, etc.), phytohormones, cyanotoxins, biocides (algaecides, herbicides, and insecticides) etc. Apart from this, the importance of these metabolites as antibiotics, immunosuppressant, anticancer, antiviral, anti-inflammatory agent has also been discussed. Metabolites obtained from cyanobacteria and algae have several biotechnological, industrial, pharmaceutical, and cosmetic uses which have also been discussed in this review along with the emerging technology of their harvesting for enhancing the production of compounds like bioethanol, biofuel etc. at commercial level. In later sections, we have discussed genetically modified organisms and metabolite production from them. We have also briefly discussed the concept of bioprocessing highlighting the functioning of companies engaged in metabolites production as well as their cost effectiveness and challenges that are being addressed by these companies.
