摘要： A method for improved anaerobic digestion is presented. The method includes mixing a volume of waste material with water to form a feedstock mixture. The volume of waste material includes an initial amount of biomass and the feedstock mixture includes methanogenic bacteria either naturally present in the waste material or introduced artificially. The method also includes introducing one or more promoter substances to the feedstock mixture. The one or more promoter substances are capable of modifying the methanogenic bacteria. Modifying includes stimulating novel enzyme production in the methanogenic bacteria.

摘要： A method for bioremediation of waters contaminated with hydrocarbons may include: putting the contaminated waters in contact with at least one polyhydroxyalkanoate (PHA); and/or allowing microorganisms, present in the contaminated waters and capable of metabolizing the hydrocarbons, to develop and degrade the hydrocarbons under an aerobic condition.

摘要： The present invention provides a nitrogen treatment method which can suppress the production of nitrate nitrogen to stabilize the concentration of nitrite nitrogen in a nitritation treatment in which ammoniacal nitrogen is biologically oxidized to produce the nitrite nitrogen. A nitrogen treatment method includes a nitrification treatment step of producing nitrite nitrogen by oxidizing ammoniacal nitrogen contained in water to be treated, using microbial sludge, wherein: a volume load of the ammoniacal nitrogen in the nitrification treatment step is set to a high load of 0.3 kg-N/m3·day or more and 5 kg-N/m3·day or less; and in the nitrification treatment step, at least one of a treatment of adjusting a pH of the water to be treated to pH 8 or more and pH 10 or less and a treatment of applying an inactivating operation for sterilizing microorganisms or causing bacteriostasis to the microbial sludge is performed.

摘要： The present invention relates to a process for the treatment of industrial alkaline streams comprising sulfide and carbonate, comprising the steps of: a) providing an industrial alkaline stream comprising sulfide and carbonate; b) supplying the industrial alkaline stream to a bioreactor comprising sulfide oxidizing bacteria and removing sulfide from the industrial alkaline stream by subjecting said stream to sulfide oxidizing bacteria in the presence of oxygen, and supplying a pH adjustment agent to the bioreactor to maintain a pH in the range in the range 8 to 11, to oxidize the sulfide to elemental sulfur, c) withdrawing from the bioreactor a treated industrial alkaline stream comprising elemental sulfur, wherein a portion of the sulfide oxidizing bacteria is removed from the bioreactor and mixed with the industrial alkaline stream prior to supplying the industrial alkaline stream to the bioreactor in step b).

摘要： [Problem] A carrier for retaining anammox bacteria, an anammox bacteria-adhered particle, and a wastewater treatment apparatus are provided that can remarkably reduce the start-up period for obtaining a nitrogen removal speed of 1 kg-N/m3/day.
[Solution] A carrier for retaining anammox bacteria includes carbon particles. The carbon particles are desirably graphite particles, particularly isotropic graphite particles. The carbon particles desirably have a zeta potential of −35 mV to 0 mV and an average particle size of 2 μm to 1000 μm.

摘要： Culture systems and methods of using same. The systems include a housing defining an inner space. The inner space includes a headspace and at least a portion of a reservoir. A surface for immobilizing cells is moveable between the headspace and the reservoir. The systems can be used for coculturing methanotrophs and phototrophs for processing biogas and wastewater, particularly from anaerobic digesters.
