“…It has been attempted since the 1980s from bacteria, fungi and yeast and was also reported to be the convenient substitutes for conventional oils because of their ability to accumulate more than 60% lipids resembling the plant and animal oils (Moon et al 1978;Davies 1988;Ratledge and Wilkinson 1989;Nichols et al 1995Nichols et al , 1997Cho Woong and Mo Jun 1999;Shimizu and Ogawa 1999). A similar pattern of distribution of fatty acids and same triacylglycerol (TAG) structure of microbial oils prove them as a feasible and cost-effective source for the production of pharmaceutically and neutraceutically important polyunsaturated fatty acid (PUFA) (Shimizu and Ogawa 1999). A number of microbes from different sources have been studied for production of SCO and PUFA (Bowles et al 1999;Papanikolaou et al 2002;Zhu et al 2002).…”

S . P A T N A Y A K A N D A . S R E E . 2005.Aim: To screen bacterial associates from marine sponges for single cell oil (SCO)/polyunsaturated fatty acid (PUFA) production. Methods and Results: Using Sudan black 'B' staining technique the bacterial associates were screened for cellular lipid accumulation, effect of culture media, incubation period and C : N ratio. Extraction of the bacterial lipids was carried out by Floch's method and fatty acid methyl esters were analysed by GC and GC/MS. Four bacterial associates of 50 isolated from eight marine sponges tested positive for lipid accumulation. Two bacterial associates, viz. Bacillus subtilis (RRL-8) from Aurora globostellata and Pseudomonas spp. (RRL-28) from Heteronema erecta were found to produce total lipids 16AE9 and 31AE7%, respectively, of their dry biomass. Conclusions: Increase in C : N ratio significantly improved lipid production to 33AE4 and 42AE7%. Both the isolates produced c-linolenic acid (18 : 3 x6; 4AE5 and 1AE12% respectively), whereas B. subtilis showed 3AE8% of eicosapentaenoic acid (20 : 5 x3) along with branched chain fatty acids. Significance and Impact of the Study: This is the first report of oleaginous bacterial associates from marine sponges.
