Diatomaceous shells extracted from benthic phenate diatoms harvested from industrial biofilm processes

摘要

The present invention relates to a process for cultivating benthic pennate diatoms in an industrial biofilm process wherein the benthic penate diatoms are in the water-comprising compartment in at least one Wherein the benthic phenate diatoms form a biofilm on the at least one surface; Harvesting the benthic penate diatoms from the at least one surface; And separating the diatomaceous shells from the organic biomass contained in the brittle penate diatoms.
