A mixture of facultative microorganisms added to pulp mill aeration stabilization basins is able to reduce sludge in situ over several months. Laboratory work shows that pulp fibers exposed to a cell-free extract prepared from the microorganisms are degraded through consumption of their hemicellulosic fraction. However, the process is quite slow; a controlled field study run for seven months did not lead to mineralization of the sludge.
