摘要: Disclosed herein are compositions, methods, and systems useful in remediating contaminants, for example environmental contaminants. In many embodiments, the contaminant is selected from atrazine and chlorothalonil, and the remediation is accomplished with a biomaterial. In many embodiments, the biomaterial comprises an enzyme that catalyzes the contaminant remediation and a gel, for example a biogel or sol-gel. In some embodiments, the enzyme is triazine hydrolase (TrzN) for example TrzN from Arthrobacter aurescens TC1. The gel may be in the form of beads, for example alginate beads, and the beads may be coated, for example in chitosan. The disclosed sol-gel may be comprised of tetramethylorthosilicate (TMOS). The disclosed compositions, methods, and systems may increase enzymatic activity and/or protect the enzyme from activity degradation due to pH, temperature, proteolysis, dehydration, etc.

摘要: Compositions and methods are provided for use in controlling souring and corrosion causing prokaryotes, such as SRP, by treating oil and gas field environments or treatment fluids with a newly identified bacterial strain ATCC Accession No. PTA-124262 as a self-propagating whole cell that produces an anti-SRP bacteriocin in situ. In another aspect, the methods use one or more toxic peptides or proteins isolated therefrom in methods to control unwanted prokaryotic growth in these environments.

摘要: Disclosed are a method and apparatus for reusing wastewater. The method for reusing wastewater disclosed herein includes: generating a mixed wastewater by mixing multiple types of wastewater (S20); performing a first purification by passing the mixed wastewater through a flocculation-sedimentation unit (S40); performing a second purification by passing an effluent of the flocculation-sedimentation unit through a membrane bioreactor (MBR) (S60); performing a third purification by passing an effluent of the MBR through a reverse-osmosis membrane unit (S80); and reusing an effluent of the reverse-osmosis membrane unit as cooling water or industrial water (S100).

摘要: The invention relates to a method for microbial remediation of underground water petroleum hydrocarbon contamination by regulating soil buffer capability, which comprises detecting the soil particle size of contaminated site soil, dividing the contaminated site soil into coarse-grained soil and fine-grained soil; dividing the contaminated site soil into high buffer capacity soil and low buffer capacity soil; and adjusting the composition and ratio of a biostimulant solution added to the contaminated site soil based on the classification of the contaminated site soil. The detecting step includes classifying soil with a particle size between 0.075 mm and 60 mm and a mass greater than or equal to 50% of the total mass as coarse-grained soil; and classifying soil with a particle size not greater than 0.075 mm and a mass greater than or equal to 50% as fine-grained soil.

摘要: Provided is a method for treating wastewater, the method being capable, even during low water temperature periods, of efficiently purifying organic wastewater that experiences large temperature differences in a year. A method for treating organic wastewater uses a device including a predetermined reaction tank containing activated sludge and a culture tank and includes the steps of: culturing, in the culture tank, a microorganism contained in the activated sludge, while maintaining a temperature of a content of the culture tank at a temperature that is at least 5° C. lower than a water temperature of the organic wastewater at a start of culturing of the microorganism and not lower than −1° C. and not higher than 10° C.; and then introducing the microorganism into the reaction tank.

摘要: “Biocathode MCL,” designated for its main bacterial constituents (Marinobacter, Chromatiaceae, and Labrenzia), is a stable microbial community enriched from seawater that forms biofilms on the surfaces of electrodes. These biofilms are effective to perform carbon fixation without the need for external electrical power nor sunlight applied thereto.

摘要: Solid, porous, glass-based substrate for storage and delivery of useful microorganisms are described. Materials include one or more microorganisms lyophilized on the substrate, e.g., in the form of a lyophilized biofilm. The materials can be utilized for long-term storage, transport, and deployment of one or more microorganisms, such as consortium of microorganisms at a remediation site.
