PROCESS FOR THE PREPARATION OF A GRANULAR MICROBIAL BIOMASS AND ISOLATION OF VALUABLE COMPOUNDS THEREFROM

摘要

A process for the isolation of desired compound(s) from a microbial biomass is diclosed, 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).
