Stable biomass based on yeast cells and lactic acid bacteria and process for its preparation

摘要

Biomass in the form of dry, substantially identical, particles containing at least 92% dry matter and preferably at least 93% dry matter containing per gram: at least 1x10<9>, preferably at least 3x10<9> and still more preferably at least 1x10<10> revivifiable cells of one or more strains of lactic bacteria, at least 5x10<9> and preferably at least 1x10<10> revivifiable cells of one or more yeast strains and less than 5% and preferably less than 3% foreign matter comprising essentially technological aids used during the drying of live cells.
