Abstract
The present invention discloses a microbial polyunsaturated fatty acid(PUFA)-containing oil with a high triglyceride content and a high oxidative stability. In addition, a method is described for the recovery of such oil from a microbial biomass derived from a pasteurized fermentation broth, wherein the microbial biomass is subjected to extrusion to form granular particles, dried and the oil then extracted from the dried granules using an appropriate solvent.
Claims31
A process for the isolation of one or more compound(s) from a microbial biomass, the process comprising:
- a) culturing microorganisms in a fermentation broth under conditions whereby the microorganisms produce the compound;
- b) pasteurising either the fermentation broth or a microbial biomass derived therefrom;
- and
- c) extracting, isolation or recovering the compound from the microbial biomass.
A process for the isolation of at least one polyunsaturated fatty acid (PUFA) from a microbial biomass, the process comprising:
- a) culturing microorganisms in a fermentation broth under conditions whereby the microorganisms produce the PUFA;
- b) pasteurising either the fermentation broth or a microbial biomass derived therefrom;
- and
- c) extracting, isolating or recovering the PUFA from the microbial biomass.
A composition comprising granular particles, the particles having been formed by granulating a microbial biomass containing at least one polyunsaturated fatty acid (PUFA).
