Abstract: The present disclosures provides isolated or purified compounds, each of which bind to a metal atom. Generally, the compounds are small in size (e.g, molecular weight of less than about 1 kDa) and peptidic in nature, inasmuch as the compounds comprise amino acids. In some embodiments, the compound comprises a structure of Formula I: M1-P1-M2-P2 wherein each of P1 and P2 is a peptide comprising at least two amino acids, M1 is a first metal binding moiety comprising a substituted imidazolone ring, M2 is a second metal binding moiety comprising a substituted oxazolone ring, and wherein M1 and M2 bind to a single metal atom. Also provided are related complexes, conjugates, cells which synthesize the compounds of the present disclosures, substantially homogenous cultures thereof, kits and compositions, and methods of making or using the materials of the present disclosures.

Abstract: A means and method for treating bacterial infection, providing antioxidant activity, and chelating copper using a copper binding compound produced by methanotrophic bacteria is described. The compound, known as methanobactin, is the first of a new class of antibiotics having gram-positive activity. Methanobactin has been sequenced, and its structural formula determined.

Abstract: A Rhodobacter species and variants thereof are provided for odor remediation of anaerobic livestock waste lagoons. Also provided are vector systems and genetically reconstituted Rhodobacter PS9 cells, and related methods for biomass production in anaerobic livestock waste lagoons.

Abstract: An odor collection station for a waste water lagoon with a buoyant housing having a top, open bottom, and opposite side and end walls. The housing having a U-shaped duct with an upper and lower passageway connected by a vertical passageway. Buoyant elements secured to the housing maintain the lower passageway at a level higher than the water surface. Compressed air forced through an inlet port of the lower passageway combines with odors that rise from the lagoon surface and are pumped through the vertical and upper passageway to an outlet port where odor components are contained, measured, and analyzed.

Abstract: The gas sample device structure has a housing with a continuous normally vertical sidewall, closed top and an open bottom. Buoyant elements are secured to the housing to maintain its vertical position in a body of liquid livestock waste. A normally closed compartment is located on the top of the housing. A partition is located within the closed compartment to divide it into first and second subcompartments. An opening is provided in the closed top of the housing to allow gases from liquid manure in the housing to move into the first subcompartment. One or more hollow gas detection tubes are mounted in the second subcompartment and have a first open end in communication with the interior of the first subcompartment to receive gases from within the first compartment. The method of the invention involves placing the housing in a liquid manure lagoon so its buoyancy is maintained by the buoyancy elements, but the lower portion thereof is submerged in the liquid manure.
