Exploring omega-3 fatty acids, enzymes and biodiesel producing thraustochytrids from Australian and Indian marine biodiversity

The marine environment harbours a vast diversity of microorganisms, many of which are unique, and have potential to produce commercially useful materials. Therefore, marine biodiversity from Australian and Indian habitat has been explored to produce novel bioactives, and enzymes. Among these, thraustochytrids collected from Indian habitats were shown to be rich in saturated fatty acids (SFAs) and monounsaturated fatty acids (MUFAs), together constituting 51-76 % of total fatty acids (TFA). Indian and Australian thraustochytrids occupy separate positions in the dendrogram, showing significant differences exist in the fatty acid profiles in these two sets of thraustochytrid strains. In general, Australian strains had a higher docosahexaenoic acid (DHA) content than Indian strains with DHA at 17-31 % of TFA. A range of enzyme activities were observed in the strains, with Australian strains showing overall higher levels of enzyme activity, with the exception of one Indian strain (DBTIOC-1). Comparative analysis of the fatty acid profile of 34 strains revealed that Indian thraustochytrids are more suitable for biodiesel production since these strains have higher fatty acids content for biodiesel (FAB, 76 %) production than Australian thraustochytrids, while the Australian strains are more suitable for omega-3 (40 %) production.

Cardiac glycosides isolated from the Indian-snuff, Maquira sclerophylla Ducke

The hydroalcoholic extract of the powdered bark of the Indian-snuff Maquira sclerophylla Ducke was purified by column chromatography in silica-gel and the major cardenolide isolated from preparative TLC was identified by 1H-NMR, 1 2 C-NMR and IR analyses. The spectra showed that the active substance has strophanthidin as aglicone.

Evaluating sustainability of an Indian university

The objective of this research is to verify the adherence between the sustainable activities of an Indian university and the variables recommended by Alshuwaikhat and Abubakar (2008) in a framework that analyzed the contributions made by Higher Education Institutions for Sustainable Development. For such, a field work was conducted in India by the first author of this article to get in-depth data about sustainability at the university analyzed. Besides direct observations and gathering documents, interviews were also conducted with professors/scholars, students and employees. It was ascertained that up to the time in which the research was performed, the university studied was not fully adhering to the framework recommended by Alshuwaikhat and Abubakar (2008). Thus, there are still several opportunities for the university studied to be more sustainable. © 2013 Elsevier Ltd. All rights reserved.
