  • LIQUID NISIN COMPOSITIONS
    Publication number: 20150335030
    Abstract: The present invention relates to liquid nisin compositions having a high anti-microbial activity. The invention further relates to a method for preparing the liquid nisin compositions as well as their use as a preservative in food products.
    Type: Application

  • PROCESS FOR THE PREPARATION OF A GRANULAR MICROBIAL BIOMASS AND ISOLATION OF A COMPOUND THEREFROM
    Publication number: 20150025260
    Abstract: A process for the isolation of desired compound(s) from a microbial biomass is disclosed, wherein the microbial biomass (which, if necessary, is pretreated to give a dry matter content of from 25 to 80%) is granulated (e.g. by extrusion) and then dried to a dry matter content of at least 80%. The granulation of the biomass to granules significantly eases subsequent drying of the biomass (which can be stored as dried granules) and gives higher yields on extraction of the compound(s).

  • Preparation of microbial polyunsaturated fatty acid containing oil from pasteurised biomass
    Patent number: 6727373
    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 deriverd 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.
