METHOD FOR ACQUIRING GRAIN-SHAPED GROWTH OF A MICROORGANISM IN A REACTOR

摘要

The invention relates to a method of acquiring granular growth of a microorganism in a reactor containing a liquid medium. Surprisingly, according to the invention, aerobic microorganisms also can be induced to granular growth by maintaining specific culture conditions. During a first step an oxygen-containing gas is supplied and the reactor contents are kept in turbulence. In a second step, after a short settling period, the top part of the reactor medium is discharged.
