“…Nonetheless, there are some useful generalized distinctions that are found with regard to the cellular content of cyanobacteria compared to algae, and plants. Under ideal growth conditions, cyanobacteria tend to be composed of relatively low carbohydrate (10–30%), intermediate lipid (5–10%) and high protein levels (40–79%), in comparison to algae (5–60% carbohydrate, 1–40% lipid, 20–50% protein) and plants (70–80% carbohydrate, 1–15% lipid, 1–10% protein) (Rajeshwari and Rajashekhar 2011; Becker 1994). With regard to carbohydrates, the dominant carbon sinks for cyanobacteria are glycogen and their exopolysaccharide layers.…”

Carbohydrate feedstocks are at the root of bioindustrial production and are needed in greater quantities than ever due to increased prioritization of renewable fuels and reduction of carbon emissions. Cyanobacteria possess a number of features that make them well-suited as an alternative feedstock crop in comparison to traditional, terrestrial plant species. Recent advances in genetic engineering, as well as promising preliminary investigations of cyanobacteria in a number of distinct production regimes have illustrated the potential of these aquatic phototrophs as biosynthetic chasses. Further improvements in strain productivities and design, along with enhanced understanding of photosynthetic metabolism in cyanobacteria may pave the way to translate cyanobacterial theoretical potential into realized application.

“…Some studies reported Spirullina and Nostoc commune contains highest amount of protein and fibre that make it an important component of human diet. Scytonema and Tolypothrix, although its lower protein content in comparison to L. majuscula, Spirullina and Nostoc commune isolated from stream system but it presented almost equal values of protein in ranges than those found for freshwater algae and marine red algae (Ciferri and Tiboni, 1985;Rajeshwari and Rajashekhar, 2011;Gressler et al, 2011), which have been used in a variety of foods throughout the world (Gantar and Svircev, 2008). Thus, Tolypothrix and Scytonema followed by other species examined could be more studied to become an option of fibres source to healthy food industry after proper scientific investigation.…”

Journal homepage: http://www.ijcmas.com Several phototrophic microorganisms, principally cyanobacteria species predominantly sheathed forms occur as biofilms on the exposed surface of stone temples, monument as well as building facades receiving areas. A study was conducted to analyse the potential of six sub-aerial cyanobacteria species belonging to three genera, i.e. Scytonema, Tolypothrix and Westiellopsis which were recorded as the main components in the biofilms isolated from 10 different sub-aerial sites (six building facades, three stone temples and one mortar monument) of Bhubaneswar and Puri, Odisha under laboratory culture conditions. The sub-aerial cyanobacteria strains were morphological characterized and changes in their biochemical constituents were analyzed in terms of total chlorophyll-a, total soluble protein, total carotenoids, total phycobiliproteins including phycocyanin, phycoerythrin and allophycocyanin, total cellular carbohydrate and extracellular polysaccharides in response to different time interval culture in BG-11 media. The analysis showed that maximum amount of total chlorophyll-a in Scytonema hyalinum (8.98µgml-1 ) and minimum in Westiellopsis prolifica (3.78µgml -1 -1 ) and minimum in Scytonema hyalinum (44.9µgml -1 ) whereas, the total extracellular polysaccharides contents were found to be higher in Tolypothrix rechingeri and Scytonema ocellatum on 32 th days growth (64.54µgml -1 and 58.98µgml -1 respectively). Study showed that Qualitative phytochemical screening of sub-aerial cyanobacteria revealed its bioactive phytochemical constituents to be alkaloids, phenol and Flavonoid etc. Acetone, methanol and chloroform are better and more efficient solvent extractors of the bioactive phytochemical constituents which vary from species to species. However, the overall response during the investigation it was observed sub-aerial cyanobacteria are prolific producers of primary and secondary metabolite(s) that may act as the antimicrobial drug resource in addition to their much explored marine and freshwater counterpart. This study is expected to contribute to data base for the drugs discovery as raw material for both biotechnological applications as well as in industrial uses for benefit of future generation.

“…Фенольные соединения представляют собой класс антиоксидантов, которые действуют как терминаторы свободных радикалов. Эти соединения были тщательно изучены в отношении их антиоксидантных свойств не только у фруктов и овощей, но и у цианобактерий (Rajeshwari, Rajashekhar, 2011). Известно, что фенольные соединения водорослей являются потенциальными антиоксидантами для борьбы со свободными радикалами, вредными для организма человека.…”
