The present invention relates to a method for preparing a concentrated polysaccharide mass, in particular a method for preparing concentrated glucan or schizophyllan, in particular a method for redispersing glucan or schizophyllan for producing a ready-to-use mass.

Redispersion of schizophyllan

The invention pertains to processes to produce dry biomass of pyripyropene producer organisms, processes to obtain pyripyropenes from such dry biomass, as well as to processes to produce compounds of Formula III and/or Formula IV and/or Formula V from the pyripyropenes obtained from the dry biomass. The invention does further pertain to the dry biomass itself, as well as processes using said dry biomass to obtain pyripyropenes for the production of compounds of Formula III and/or Formula IV and/or Formula V, including processes using said dry biomass to obtain pyripyropenes or compounds of Formula III and/or Formula IV and/or Formula V in order to produce pest control compositions, in particular insecticides, comprising such compounds.

Production of pyripyropenes from dry biomass

The invention relates to a method for isolating 1,5-diaminopentane (DAP) from DAP-containing fermentation broths, to a method for the fermentative production of DAP using said isolating method and to a method for producing DAP-comprising polymers by using the DAP isolated or fermatively produced DAPs according to said methods.
