    Abstract: The bioconversion of gas feedstreams to liquid products by direct contact with a layer of microorganism obtains enhanced productivity through the regular cycling of liquid across a substrate that supports a biolayer of microorganisms while separating the gas and liquid phases. Such processes produce liquid products such as ethanol, butanol and other chemicals from syngas components by contacting CO or a mixture of CO2 and H2 with a highly porous side of an asymmetric membrane under anaerobic conditions and transferring these components into contact with microorganisms contained within bio-pores of the membrane. A periodic laving of liquid from the liquid contact side to and away from the microorganisms can increase nutrient flow to the microorganisms while enhancing the recovery of liquid products.

  • Patent number: 8187462
    Abstract: A process is provided for increasing the production of PHA in a mixed culture biomass. In a first stage of the process, organic material associated with a substrate is converted to volatile fatty acids. In the case of a wastewater treatment process, if the wastewater includes sufficient volatile fatty acids (VFAs) to support the process, then it is unnecessary to convert organic material to VFAs. In a second stage of the process, an anaerobic-aerobic selection process is utilized to select glycogen accumulating organisms that cause these organisms to proliferate and dominate the open mixed culture biomass. By providing relatively high organic loading in the form of VFAs in the anaerobic treatment phase of the selection process, glycogen accumulating organisms having a relatively high level of stored glycogen are produced. In a third stage, the PHA accumulation process is practiced where the glycogen rich organisms are fed VFAs under anaerobic or aerobic conditions or combinations thereof.

  • Publication number: 20120100598
    Abstract: Different bioremediation agents' effectiveness against concentrations of diesel fuel in soil were tested. The purpose of this experiment is to find a quick, clean, and cost-effective alternative to current remediation techniques using new bioremediation techniques. Analysis indicated that the use of a mixture of Linoleic acid and R. rhodochrous generated the greatest, quickest, and longest lasting degradation rate. The mixture provided a 51.23% drop in PAH and data suggests that it will to remediate after the end of the 4th week. In second place came the Linoleic acid with an immediate drop of 36.61% before leveling out in the 2nd week. The bacteria (R. rhodochrous) started slow but moved into a greater rate every week bringing it to an overall 46.65% change. The hypothesis that the mixture of the R. rhodochrous and Linoleic acid would yield the greatest PAH degradation was supported by the data.

    Abstract: A method for processing environmental or industrial samples to remove, reclaim or otherwise reduce the level of chemical species present in the sample that act as redox active species. The redox active species is kept in a waste chamber and is separated from an aqueous bacterial culture that is held in a culture chamber. The waste chamber and the culture chamber are separated by a porous membrane through which electron transfer can occur but through which the aqueous bacterial culture cannot pass. The redox active species substantially remains in the waste chamber and is in non-contact with the aqueous bacterial culture during the process of removal, reduction or reclamation.

  • Patent number: 8153006
    Abstract: A method of treating thin stillage from an ethanol production process that includes in a digester, treating thin stillage from the ethanol production process using anaerobic digestion to produce an ammonia-rich liquid product. During anaerobic digestion of the thin stillage, with a solids/liquids separation system of the digester, the ammonia-rich liquid product may be separated from a mixed liquor to produce a permeate. At least a portion of the permeate from the solids/liquids separation system of the digester may be recycled directly to the ethanol production process. A mesophilic anaerobic digester with a thin stillage COD loading rate of about 3 kg/m3/d to at least about 7.5 kg/m3d. An anaerobic biomass prepared by a method that includes subjecting the biomass to at least one stress event.

  • Publication number: 20120083026
    Abstract: A method and arrangement for removing CO2 from smoke or exhaust gas of a combustion process in a power plant are provided. The exhaust gases comprising CO2 are fed into a tank in which cellular organisms, such as micro algae, are present, converting the CO2 into biomass when nutrients are added. The micro algae and/or the generated biomass have magnetic particles added, which combines with the algae and/or the biomass.

  • Patent number: 8124401
    Abstract: The invention relates to a method and a system for producing biofertilizers, from sludge that are stabilized, dried, and rich in fertilizing matters originating from high load effluent treatment method. Such solution may be integrated into an already existing treatment facility for industrial, municipal, or agronomical organic effluents (100), and is based on recovering the thermal energy created during the treatment steps of such system in bioreactors (120), air suppression units (122), biodrying units (500), drying units (600), and other units. Such recovery of energy creates a synergy that allows the increase of efficacy and yield of bioreactors (120) due to a greater stability from the temperature regulation, thus ensuring an important energy saving for the final drying step in producing biofertilizers.

  • Patent number: 8114659
    Abstract: This apparatus introduces catalysts and fluids into a media to effect remediation of contaminants, improve soil fertility and permeability, control undesirable pests, or create useful chemicals or food. The apparatus generates and releases enzymes, metabolites, and biologically active organisms. Aerobic metabolism of compounds in a media is facilitated through the transfer of fluids, such as air. The apparatus and methods provide an environment for select organisms, including refugia and nutrient substrate. The biodegradable composition of the apparatus is partially transformed by catalytic treatment. Catalysts or remediation agents are produced in-situ, for specific applications that provide a range of retention, activation, activity, and release profiles. The apparatus is placed in contact with media. Catalytic infusion of media by biological consortia, such as fungi, releases exudates that transform or biodegrade materials.

  • Publication number: 20120021499
    Abstract: A method for removing pollutants in pollutants-contaminated soil is disclosed. The method includes following steps. A biodiversity system with microbial biodiversity characterization is used to induce growth and reproduce of at least one dominant synergistic flora for petroleum degradation. Most of the petroleum in the soil can be degraded when the temperature of the biodiversity system is below 30-50° C. The remained petroleum in the soil is than rapidly washed out from the soil through forming a petroleum-in-water emulsion by biosurfactant synthesized by the microorganisms in the biodiversity system.
