Application of sugar-cane molasses in the production of lipids by yeast

RESUMO

The possibility of using fat as food and fuel and the production of specific compounds from lipids has led research about micro-organisms capable of conversion carbohydrate into lipids. The microorganisms Candida parakrusei, Hansenula suaveloens and an unidentified yeast "yeast", isolated from sugar-alcohol sector have been studied for lipid productions utilising sugar-cane molasses and molasses supplemented with sodium chloride and calcium panthotenate. This factors stimulated the lipids total productions to the three micro-organisms. The major values was 60,26 per cent; 53,97 per cent and 58,46 per cent to C, parakrusei in NaCl at 0,1 N, H. suaveloens in calcium panthotenate 4ug/mL and yeast "a" in calcium panthotenate 16ug/mL respectively. Furthermore strain "a" achieved the highest values of phospolipids while strain C parakrusei the higest values of sterol and protein. The fatty acid analysis of strains showed predominance of oleic palmitic and linoleic acid
