Abstract
The present invention relates to polymeric particles comprising a biodegradable polymer, and at least one microorganism in a total concentration of at least 108 CFU/g dry weight that is stable for at least 35 weeks at 30° C. and optionally additional carriers and additives as well as to methods for producing polymeric particles and use thereof.
Claims11
A polymeric composition, comprising polymeric particles which contain one or more microorganisms in one or more multicellular aggregates embedded in a self-produced extracellular biogenic matrix, wherein the self-produced extracellular biogenic matrix comprises naphthazarin, and wherein at least one microorganism has a total concentration of at least 108 CFU/g dry weight and storage at 30° C. for 14 weeks resulting in less than 1 log 10 loss CFU/g dry mass.
