  • Biological agent for enrichment of anaerobic digestion reactors, method of preparing such biological agent and bio-augmentation process with said agent
    Patent number: 11293036
    Abstract: Biological agent for bio-augmentation of an anaerobic digestion reactor, named first anaerobic digestion reactor, comprising a mixture of microorganisms including at least 10% of relative abundance in said mixture, of a unique Cloacimonetes sp. This agent is prepared by enrichment of a biological sample in a separate reactor fed with carbohydrate-rich substrate and oxygenated gas. Said agent comprising this unique Cloacimonetes sp. is able to restore and stabilize the biogas production of an anaerobic digestion reactor after acidosis, in a very short time.
    Type: Grant

  • Process for controlling and monitoring the production of biogas
    Publication number: 20130022959
    Abstract: The present invention relates to a process for online and direct control of production of biogas in an anaerobic digester comprising the steps of: a) feeding the anaerobic digester with organic substrate, b) extracting a sample of biogas from the headspace of the anaerobic digester, c) analyzing the composition of the sample of biogas and detecting the quantity of one or more volatile fatty acids in said sample of biogas, d) controlling feeding of the anaerobic digester in view of the quantity of the one or more volatile fatty acids detected in said sample of biogas.
