“…GLA is also reported in fungi such as Mortierella ramanniana (Hansson & Dosta´lek 1988), Mucor sp. (Shin & Shin 1988), Cunninghamella japonica (Galanina et al 1988), Entomophthora exitalis (Kendrick & Ratledge 1992) as well as in the cyanobacteria, Spirulina (Nichols & Wood 1968;Pelloquin et al 1970;Hudson & Karris 1974;Cohen et al 1992), Synechocystis (Wada & Murata 1990), Microcystis and green alga Scenedesmus (Piorreck et al 1984). Therefore, microalgae seem to be the prospective GLA resource.…”

Pharmaceutically important c-linolenic acid (GLA) was produced (4.1 mg g )1 dry wt) by laboratory grown cyanobacterium Fischerella sp. colonizing Neem (Azadirachta indica) tree bark. GLA isolated from the test cyanobacterium was active against Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25992, Salmonella typhi (local strain), Pseudomonas aeruginosa ATCC 27853 and Enterobacter aerogenes MTCC 2822. The overproduction of GLA was also monitored by altering phosphate and nitrate levels in the nutrient medium. A doubling in phosphate concentration (58 lM) increased GLA level up to 12% over that of control cells while half of this phosphate level reduced GLA synthesis by 8%. In contrast, elevated nitrate concentrations (5 and 10 mM) stimulated biomass yield but not GLA, as the levels approximated to the nitrate-lacking control. The antibacterial potential of GLA from Fischerella sp. grown at varying P or N levels was at variance as evidenced by the diameter of inhibition zones against S. aureus. This variation in inhibition zones reflected differing levels of GLA as ascertained quantitatively by HPLC.

“…Holton et al (1964Holton et al ( , 1968 and Parker et al (1967) analysed a strain of Anacystis, a unicellular cyanobacteria of subsection I, and found an absence of polyunsaturated fatty acids ; this observation was confirmed and extended by Kenyon (1972) and others (Kenyon & Stanier, 1970 ;Kenyon et al, 1972 ;Scheuerbrandt & Bloch, 1962 ;Stanier et al, 1971). The composition of filamentous strains of most genera of subsection III have been studied (Ahlgren et al, 1992 ;Cohen et al, 1993 ;Hudson & Karis, 1974 ;Tedesco & Duerr, 1989) as well as some from subsection IV (Ahlgren et al, 1992 ;Caudales & Wells, 1992 ;Caudales et al, 1995 ;Hudson & Karis, 1974 ;Sallal et al, 1990 ;Sandmann & Boger, 1992 ;Sato & Murata, 1981) and subsection V (Kenyon & Stanier, 1970 ;Kenyon, 1972 ;Kenyon et al, 1972). …”

The cellular fatty acid composition of five of the six genera of unicellular cyanobacteria in subsection II, Pleurocapsales (Dermocarpa, Xenococcus, Dermocarpella, Myxosarcina and the Pleurocapsa assemblage) contained high proportions of saturated straight-chain fatty acids (26-41 % of the total) and unsaturated straight chains (40-67 %). Isomers of 16 :1 were the main monounsaturated acid component (11-59 %). Polyunsaturated acids were present at trace levels (01 % or less) in Xenococcus and Myxosarcina, at concentrations of less than 7 % in Dermocarpa, Dermocarpella, Pleurocapsa and CCMP 1489, and at high concentrations (35 % or more) in Chroococcidiopsis. Chroococcidiopsis was also different in terms of the percentage of 16 :1 isomers (10-12 %) compared to other genera (30-59 %), and in terms of total 16-carbon and 18-carbon fatty acids. In general, the composition and heterogeneity of fatty acids in the order Pleurocapsales was similar to that reported for the unicellular cyanobacteria of subsection I, order Chroococcales.

“…Arthrospira (∼20 g) can provide the required regular doses of vitamin B 12 and 50% of vitamin B 2 (riboflavin), 70% of B 1 (thiamine) and 12% of B 3 (niacin) in humans (Switzer, 1981). It also contains a fair amount of tocopherol (vitamin E), which is almost three times that of pure wheat germ (Hudson and Karis, 1974). The native population of the lake Chad region of Africa uses Spirulina (Arthrospira) as hardened, sun dried mat (Dihé) as a food supplement rich in proteins, minerals, carotenoids, vitamin E, folate and lipids containing essential unsaturated fatty acids (Carcea et al, 2015).…”

Sustainable supply of food and energy without posing any threat to environment is the current demand of our society in view of continuous increase in global human population and depletion of natural resources of energy. Cyanobacteria have recently emerged as potential candidates who can fulfill abovementioned needs due to their ability to efficiently harvest solar energy and convert it into biomass by simple utilization of CO 2 , water and nutrients. During conversion of radiant energy into chemical energy, these biological systems produce oxygen as a by-product. Cyanobacterial biomass can be used for the production of food, energy, biofertilizers, secondary metabolites of nutritional, cosmetics, and medicinal importance. Therefore, cyanobacterial farming is proposed as environment friendly sustainable agricultural practice which can produce biomass of very high value. Additionally, cyanobacterial farming helps in decreasing the level of greenhouse gas, i.e., CO 2 , and it can be also used for removing various contaminants from wastewater and soil. However, utilization of cyanobacteria for resolving the abovementioned problems is subjected to economic viability. In this review, we provide details on different aspects of cyanobacterial system that can help in developing sustainable agricultural practices. We also describe different large-scale cultivation systems for cyanobacterial farming and discuss their merits and demerits in terms of economic profitability.
