Genus Pyropia is one of the nutritionally rich marine algae. Among Indian Pyropia species, Pyropia acanthophora has been documented as a new addition with its new variety robusta. Biodiversity assessment revealed that P. acanthophora var. robusta reported only on the central west coast of India during monsoon (June to September). The nutritional composition of the collected samples was evaluated for proximate analysis along with vitamin C, dietary fiber, pigments, minerals, and fatty acid composition. The protein content was in the range of 14.11 ± 0.62 to 18.36 ± 0.90 g (100 g)−1 dry wt. Lipid content ranged from 1.65 ± 0.25 to 2.56 ± 0.40 g (100 g)−1 dry wt., and the concentrations of PUFA among these lipids were found in considerable quantity. Dietary fiber was also obtained in high concentration and ranged from 45.13 ± 1.30 to 63.0 ± 4.40 g (100 g)−1 dry wt. In this study, the level of K, Na, Mg, Fe, I, and P were appreciably high. Thus, the nutritional analysis of P. acanthophora var. robusta confirmed that it has potential to be used as an ingredient for nutritional supplements. © 2017 Springer Science+Business Media Dordrecht

The present study describes production of bio-ethanol from fresh red alga, Kappaphycus alvarezii. It was crushed to expel sap - a biofertilizer - while residual biomass was saccharified at 100°C in 0.9N H 2SO 4. The hydrolysate was repeatedly treated with additional granules to achieve desired reducing sugar concentration. The best yields for saccharification, inclusive of sugar loss in residue, were 26.2% and 30.6% (w/w) at laboratory (250g) and bench (16kg) scales, respectively. The hydrolysate was neutralized with lime and the filtrate was desalted by electrodialysis. Saccharomyces cerevisiae (NCIM 3523) was used for ethanol production from this non-traditional bio-resource. Fermentation at laboratory and bench scales converted ca. 80% of reducing sugar into ethanol in near quantitative selectivity. A petrol vehicle was successfully run with E10 gasoline made from the seaweed-based ethanol. Co-production of ethanol and bio-fertilizer from this seaweed may emerge as a promising alternative to land-based bio-ethanol. © 2011 Elsevier Ltd.

Jatropha is a potential biofuel crop suitable for growth on degraded lands. There is no conflict between food and fuel with the use of this plant. Against this backdrop, the research of our institute has been focused on cultivation on wastelands, where conventional crops cannot thrive. If merely neglected, wastelands are further degraded and eventually become deserts. These barren lands naturally sustain low diversity of flora and fauna and can support only abysmal ecosystem services. Jatropha cultivation has been shown to improve the soil properties of such lands. This article documents different flora and fauna frequently observed in the transformed ecosystem brought about by the resultant land use change. The article also discusses the ecosystem services gained in the process. Thus, economic and climate change benefits result from Jatropha cultivation in wastelands. © 2014 © 2014 Taylor & Francis.
